Hello Everyone! I have started a second channel called "Roar!" where I take on challenges and push myself out of my comfort zone. You can check it out here: th-cam.com/users/roarrawr
Today it was -20 in Ottawa. That's about when the snow underfoot starts to creak. At -45 (my coldest outdoor adventure) the snow has a high soprano squeak. For me, it's only really cold when you hear the snow creak. We're kind of like Shetlanders that way, there isn't bad weather only bad clothing.
Here in the States I notice that change in the way that snow forms into flakes and squeaks under foot right around 0°F, so yeah, that fits your observations, too. I love the way light shimmers off of fresh accumulations of these larger flakes as one walks past.
Looking forward to this one...I can remember taking a physics class and the professor mentioning how cold temps affect sound waves...always wondered how that would affect singers.
Another feature of snow is the sound it makes when you walk on it. Above -15C, there usually isn't much sound, but as it gets colder, it squeaks. I love walking about in the winter, listening to the sounds. This video was delightful.
Exceptional video, Beth!!! I think going down your "Beth Chats" playlist is going to be intoxicating!! BTW, the quite after freshly fallen snow, one of my favorite 'sounds'...❄
Thank you for this wonderful theory based input, Beth. As a music teacher myself, teaching children and young adults at school here in Germany, your content is a great inspiration for my own lessons and for picking up topics I haven't thought of before. Thank you for this fantastic content!
I thought you were going to analyze the ice sounds recorded by Jonna Jinton in northern Sweden at the lake near her abode. Please check her channel if you're not familiar with her and it. In any case, your spoken essay is interesting, informative and contains much beauty. Thank you.
Very cool (no pun) segment. I have almost always lived where it snows in the winter and can't imagine what it would be without it. Sucks to drive in, but that's why we have 4WD. It is amazing how clear the sound is after a winter storm and how it feels like you could belt for miles.
Hi Beth. It's nice to hear how your explainations are both acurate and poetic. Air also acts as a low pass filter, with a slope that depends on temperature and humidity, but the main reason why we hear distant sounds, you explained it perfectly. Concerning the streams comparison, I recorded hundreds of water streams, rivers and none of them sound alike, because the water path is different, obstacles making turbulences, flow, depth, river shore acoustics, there are dozens of factors that change the sound. I think the water glass experiment is the only way to isolate only the temperature factor. Cheers.
Growing up in the north of Sweden, straddling the Arctic Circle, the contrast between the frigid winters and balmy summers was greatly appreciated. :) The sound of a lake as it freezes over in autumn, the almost otherworldly _"twanggggg-ggg"_ as the ice expands, sending spears of sound from one side of the lake to the other ... the groaning and whip-cracking sounds from the woods during the coldest days, and the soundproofing of two metres of snow cover ... just magical. The effect is probably amplified by the polar night, since the absence of daylight even during mid-day will attune your body to sound more readily ... unless the aurora is visible, in which case one's eyes would be fixed on the sky in awe of the beauty of the natural world.
There is a festival in Ottawa each February called Winterlude that takes advantage of the Rideau Canal being frozen over. (Well, in years when we are allowed to congregate.) We saw the Barra MacNeills of Cape Breton perform outside Ottawa City Hall when it was -18C. The were wearing fingerless gloves and there were propane heaters that kept their legs warm but the wind was blowing a bit. Lucy MacNeill commented in a later interview that the only problems were letting her viola cool down before tuning it and remembering not to take any gulping breaths. It was wonderful, even if my toes needed an hour to warm up when we got home. PS their version of Coal Town Road is great and their original violin duet, Beautiful Point Aconi, makes you homesick for a place you've never heard of.
I would be interested to hear your thoughts on singing outdoors in the cold vs say in the summer time....from the perspective of a vocalist and listener....does it change the way you approach preparation and singing? Does it affect the tone or timbre of the voice that an audience hears?
Come to Minnesota when it's -32°C and listen to meet plants fly overhead. Crazy different sound than in warm weather. Sharp, sharp crackle of the engines and air moving through the engines. The air blowing through trees - very different. Snow underfoot squeaks.
I just loved this video. Rosslyn Chapel recently had an interesting study by a lady who used the cymatic patterns and converted the frequencies to a composed acoustic recording. It is astonishing. I would love to hear the "tunes" each snowflake produces.
Where I live we get snow about once every 30 years, but we do get fog that forms due to an inversion layer, and I can verify that it does make sound travel further along the ground. I can hear train whistles clearly in winter, despite the fact that the nearest train tracks are almost three miles away.
You have nice, calm voice, it's relaxing to listen to you. That thing with temperature inversion is real, I remember hearing sounds from main train station that is two kilometers far through the city center and temperature inversion is nearly every day from November to January with dull overcast sky. But there is other kind of temperature inversion - when sky is clear in the winter, heat from the ground is irradiated into space, nights get much colder in the winter (actually sometimes even in the summer) and layer of air close to the ground is the most cold. Usual result is dew from condensing water or some tiny ice needles on grass or fallen leaves. Or fogs in the valleys. Or frozen car window when it's slightly above zero degrees.
A couple of months ago we had lightning while it was snowing, it was heard across Fife and Edinburgh. Here in Fife it sounded like a loud slow flying jet over head, not a crack or bang you hear normally.
Sometimes, as a kid, I would lie down during a snowfall and was able to hear individual snowflakes falling and landing on the snow next to my ear 👂- now I live in Florida and can get a tan in the winter, lol 😁
an interesting experience.as a native northerner, I immediately hear cold water, determine the air temperature by the creak of snow under my feet + - 5 degrees.I think the presence of a musical ear is not necessary.The one who drinks water from a spring all his life will immediately determine the quality of other water, even by the smell, which the water does not seem to have:). All this happens automatically,your video made my brain think about it.
I'm still loving these new style of videos Beth. So informative and pretty to watch. And the prettiness counts double on your B-roll and the B-roll shorts that you create.
Great video, Beth! Sorry, I've just come across your channel - and immediately subscribed! If you're still doing the experiment, I think #1 sounded colder. But won't there be many other factors with two natural streams? They won't have exactly the same width, depth or speed of flow - or at least, it would be quite a challenge to control for these other parameters. Did you manage to find two streams that were well matched in these regards?
All I have to say is WOW. You just explained / proved to me something i kinda knew my whole life. I love a nice gentle snowfall! Its so PEACEFULL! Quiet Relaxing Keep up the good work!!
Super interesting! I wonder if the effects of cold on how we interpret sound has affected the way accents have developed in different countries? Hot climate maybe more of the twang, more head voicr, cold climate deeper and more mellow chest voice tones? Thinking the broad tones of of the scandinavians vs the nasally pitch of the Australian.
With voice it should effect too much as the air warms when it travels through your body meaning it is travels in much the same way whether it is hot or cold. However it may travel slightly differently once it leaves your mouth. However it is really interesting with accents as they say accents with more closed vowels develop in the cold and open vowels in the warm as you want to open your mouth more and don’t need to keep heat in your body
My mothers Maiden name was Hoare. This name is a specific sound that water makes on plants as it freezes, just as the adiabatic rate of water vapour in the surrounding atmosphere approaches -9 C and the water vapour goes from gas to solid without a liquid phase, hence 'falls' out of the air. In this case the air is less dense just above the grass or vegetation, and the sound "roars" with a Hoar sound hence HoarFrost. The sound is eerie with a breathy instant, and travelling cold sound. If you happen to be standing in a field as it roars around you towards you and then away the frequency of the sound changes, not just with the doppler effect but also the crispness of the crystals rapidly forming and growing making a following "shhh", then silence. Following just after is a wonderful "ping" as the now solid crystals stand in-place and resonate off each other for a second or two. The name Hoare or Hoar, means "white beard like"
Ive always heard the cold as i like the outdoors but i also think that your vison is clearer. Maybe its that there is less humidity or polution because the molecules are closer. cars also run better in the colder oxygen rich air. Anyway great video! Cheers!
The way sound travels in the more dense cold air, is the same system/reason you can hear a train from far away by listening on the rails. Also, stream 1 sounded colder.
In software to calculate line arrey’s (those speakers on festivals that hang up) you can give in the temperature. Also in the measurement software to accommodate with the physical difference of cold or hot air. Also dry or wet air can change sound significantly.
Stream #2 sounds colder to me. I glanced through the comments and my view (or hearing) seems to contradict with general view (or hearing :)) but the second stream sounds harsher, like more viscous, so the second one it has to be (colder)
This is a fantastic video about a very interesting phenomenon. When it gets really cold, your shoes start squeking against the snow. The same with car tyres. It's very noticeable and can be grating. Also, at -15C or so your thighs and arms make louder swishy sounds as they rub together and against your sides respectively. And atleast some synthetic fabrics sound like sheet of paper being scrunched and at even colder temperaturs you'll feel like you're wearing origami. So it's *squek* *squeak* *swish* *swish* *crunch* *crunch* . The coldest I've been in is around -40C, and every other winter at roughly -30C. It becomes quiet and if you're near a forest, you'll hear bangs and snaps as the trees contract in the cold. It can sound like sporadic gunfire in the cold silence. Burning wood can make similar sounds, which is interesting.
In German, very cold temperatures are referred to as "klirrende Kälte". The sort of cold when the crunch of the snow when walking changes tone. The best translation the dictionary offers would be "clinking cold", although it still doesn't feel quite right. Think of a big pane of glass shattering. Also, the word "klirren" evokes just the right feel. Sometimes, the proverbial harshness of the german language really comes in handy.
Temperature inversion is the other way around I believe, the warm air is trapped close to the ground by a layer of cold air. You see this quite often here in Norway. The mist on ponds, lakes, rivers, in whole valleys and here in Oslo. The air quality in Oslo sometimes deteriorates in the winter because the cold air from the surrounding mountains pours down the mountain sides and covers and traps the warm air rising from the town. Occasionally it is "vindstill" (no wind) in the town causing smoke and vapour to rise vertically. The cold air is as I said pouring down from the mountains and is thus obviously moving. This results in in the smoke/vapour from chimneys and the like rising straight up through the still warm air until it hits the cold moving air and then abruptly changing direction. This also tells you exactly where the two layers meet. The air quality deteriorates because the pollution stays in the pocket of warm air rather than dispersing into the atmosphere as it normally would do.
Hey! I'm not sure what that is called or even if it has a name but often the warmer air will be the air nearest the ground. However temperature inversion is definitely the opposite where the cold air is trapped under the hot air. www.britannica.com/science/temperature-inversion
Why does live music often sound best and most beautiful amidst the trees?... my personal hypothesis is that outside in nature the sound waves can travel endlessly and aren't suddenly blocked by walls and at the same time the trees filter the sound in a pleasent and organic way so that any unintended reverberation and echo is naturally prevented and voices and instruments can be heard in what might just be (one of) their most pure and unaltered states.
Oh, ooh. Nice. How about the one when it's clear sky, daylight, forty below zero & the water freezing out of the air makes a fine little jingling noise. or hearing Northern Lights.
Stream 1 sounded tropical and Stream 2 sounded cold, but i wouldnt say i'm hearing the water as cold, more the flow rates or the way the water is interacting with the surroundings. I also think this might have something to do with the glass as well, i feel the cold water shocks the glass so to speak causing it to ring/ resonate higher.
Great video, now I almost miss cold days ;) edit: completely forgot. I'll go with stream 1 as being the cold one and not only because I don't think that you'd use #2 both times ;) The second one was more lively which doesn't align with being more viscous
i heard a sound of water and ice in the glass cup 2 like you're putting and ice cube on the glass, hot water sounds quite, soft, cold water sounds high it vibrates the glass more than hot water. 3:38 min stream 1 hot soft, low frequency, stream 2 cold hard high frequency. i conclude its nice to listen to music/song at night or in cold temp. rather than in the daytime or warm temp.
Talking about winter in the UK? Pssh your winter is October weather. Beth's super power is obviously bringing much happiness and smiles with her videos. 😎
I hear insects in the winter. It's so subtle, I think I must be imagining the sound, yet the sound of a chorus of insects persists. Please restore my sanity!
I would LOVE to see you react to "Hellfire" by Tomi Pizur. It's absolutely INSANE! He uses SIX OCTAVES of range in it. Be prepared for HEAVY bass and crazy high notes!
Not just in Scotland, I can hear all the phenomenon you mentioned here in southern England, you just Need to be in tune with your surroundings and Mother Nature. 😉 Oh and stream 1 is cold.
I'd guess! with glasses pouring! my half Scottish origin does works! blood never lies..? for me the cold one stream is the stream 1; I'd think is because through the air humidity crystalize and goes down and for me this "compress down " the waves of sound into the lower levels and travel more longer, and sounds among crystals reverberate more reflectively by micro-crystals in the air? (not scientific, is only my thought) Yes, I love this kind of videos..

I'm from Central Montana. Squeaky snow. You just made my day.
I think stream 1 sounded colder, but it is close
I thought it was 1 as well
I guess I'm in the 2% cuz 1 sounds colder to me😭. I even started over to see if I missed something and 1 still sounds like it's colder
Beth, can you do a segment on tone deafness?
Yes please!

I imagine the denser air also works like water for whales' long-distance calls.
Maybe. I don't know much about acoustics in water. I'll have to research!
Fluid mechanics includes sound waves, and both are fluids.
It does, is in fact used by submarines to conduct listenings of longer distances. The cold eater has closer molecules that conducts the sound better.
This was amazing!!! Thank you ♥

Wow this is some top quality content Beth! I'm going with stream 2 for the cold one. I see that contradicts most other guesses though!
Thanks 🙏🏻
Always adoring your Scottish accent as well as your content. I loved working in Aberdeen.
This is a fantastic video about a very interesting phenomenon. When it gets really cold, your shoes start squeking against the snow. The same with car tyres. It's very noticeable and can be grating. Also, at -15C or so your thighs and arms make louder swishy sounds as they rub together and against your sides respectively. And atleast some synthetic fabrics sound like sheet of paper being scrunched and at even colder temperaturs you'll feel like you're wearing origami. So it's *squek* *squeak* *swish* *swish* *crunch* *crunch* . The coldest I've been in is around -40C, and every other winter at roughly -30C. It becomes quiet and if you're near a forest, you'll hear bangs and snaps as the trees contract in the cold. It can sound like sporadic gunfire in the cold silence. Burning wood can make similar sounds, which is interesting.
In German, very cold temperatures are referred to as "klirrende Kälte". The sort of cold when the crunch of the snow when walking changes tone. The best translation the dictionary offers would be "clinking cold", although it still doesn't feel quite right. Think of a big pane of glass shattering. Also, the word "klirren" evokes just the right feel. Sometimes, the proverbial harshness of the german language really comes in handy.
That was so interesting! I appreciate this kind of information very much, thank you!

Oh, ooh. Nice.
How about the one when it's clear sky, daylight, forty below zero & the water freezing out of the air makes a fine little jingling noise.
or hearing Northern Lights.
When it gets cold enought (like that example from Canada) trees also cracks like rifle shot...
I recently discovered that i can hear when my tap water has reached a hot temp
Thank you for this, I very much enjoy learning the why and how behind things I love.
Both streams sound exactly the same to me. I actually didn´t even noticed when you switched from one stream to the other...
same didn't notice when it switched but would gues 1
Stream 1 sounded tropical and Stream 2 sounded cold, but i wouldnt say i'm hearing the water as cold, more the flow rates or the way the water is interacting with the surroundings.

The color of your eyes accompanied the color of your blouse. Great video, Beth, your editing is great.
To me stream 1 is colder as it's crisper/sharper in sound. Whereas stream two isn't as crisper/sharper.
I can't hear that well, but I love the sound of her voice!
Great video, now I almost miss cold days ;) edit: completely forgot. I'll go with stream 1 as being the cold one and not only because I don't think that you'd use #2 both times ;) The second one was more lively which doesn't align with being more viscous

To me, the "hearing cold" test was somewhat backwards. I can hear if running water is hot. #1 sounded hotter.
I enjoyed listening to this topic very much. It’s -15 C here so I chose a great day to listen. Well done!
Physics is so beautiful and intriguing.
The similarity between Hydrodynamics and Aerodynamics is the medium described in both is considered a fluid.
Sound can travel between 2 different layers of water with 2 temperature gradients for hundreds of miles depending on salinity and pressure.
Cool subject

I'd say the 1st stream is cold and the 2nd stream is hot. The thick sound in the 2nd one indicates warmth to me.
I love the silence during a snow storm.
Makes sense from a physics perspective. A pressure wave travels differently through high-energy molecules than through low-energy molecules.
Cery interesting!
Great video!
Thanks for watching!
🤯🤯🤯 my smooth brain just got a fold. Absolutely astounding, I’ve always loved cold weather and this just adds onto my love for it
Stream 1 cold
Stream 2 warm
Just an incredible video, Beth.
Once more I'll send you greetings and salutations from Brazil. Hope this sentiment reach you.
Yes, us Canadians get some really cold weather. You should check out frost quakes and thundersnow.
Beths voice is perfect for this style of video. :)
well i was wrong on the water pouring one :/ but my guess is stream one is the cold one. love the sciencey vids Beth!!!
Beth, I think Stream 1 was the Cold. ???
The second stream is definitely the warmer
stream 1 is cold, stream 2 is warm
I hear insects in the winter. It's so subtle, I think I must be imagining the sound, yet the sound of a chorus of insects persists. Please restore my sanity!
Lovely video!
Great i love what you doing... Yr always the best i love you piece
I always wondered if the trees losing their leaves affected the transmission of sound.
I’m sure it does in highly forested areas.
I Beth, you really need to check Gabriel Henrique - I have nothing (whitney Houston)
Please look at Apocolyptica "Bittersweet",two voices in one song!
Yes please. Or anything by HIM / Ville Valo.
I would LOVE to see you react to "Hellfire" by Tomi Pizur. It's absolutely INSANE! He uses SIX OCTAVES of range in it. Be prepared for HEAVY bass and crazy high notes!
was it recorded in a cold or hot place?
@@trinitycreen He recorded in the Czech Republic where he lives, so I'm guessing cold
Ice see what you did here, I snow what you mean. Cold not be any clearer.
Was the warm cup of water heated? It sounded warmer than room temperature. There was a softness to it.
Yeap :)
I actually can hear the hot/boiled water sound rather than the cold sound so that's how I knew cup 2 was hot/warm.
Not just in Scotland, I can hear all the phenomenon you mentioned here in southern England, you just Need to be in tune with your surroundings and Mother Nature. 😉
Oh and stream 1 is cold.
I felt like drinking a glass of water.
anyhoo the second one is cold....
Hi Beth 👌⭐⭐⭐⭐😊❤️❤️❤️
Thanks for the ❤ Beth.....but PUHLEASE react to Karise Edens version of Hallelujah...you won't regret it... PLEASE....roar
I'd guess! with glasses pouring! my half Scottish origin does works! blood never lies..? for me the cold one stream is the stream 1; I'd think is because through the air humidity crystalize and goes down and for me this "compress down " the waves of sound into the lower levels and travel more longer, and sounds among crystals reverberate more reflectively by micro-crystals in the air? (not scientific, is only my thought)
Yes, I love this kind of videos..
Maybe you are right! So many explanations. I love that we are aware of so much in our environment that we don't actively think about.
Cup 2 sounded almost “crispier.”
