I get the concept of measuring first and designing for the max frequency and amplitude. I also get this is unique for every room. I would still love a video where you actually design a barrier wall with a particular goal.
With the noise numbers, you can then design the barrier more accuately. Noise < 125 hz. is dealt with much differently than noise issues above 25 hz. That is just one variant that must be considered.
Sir , kindly advise. My neighbour pointed a electric kitchen chimney exaust pipe towards my balcony. How to reduce maximum sound. Chimney around 15 feet distance.
All noise must be measured for frequency and amplitude before a proper barrier design can be built. We can assist you with the process and provide you the drawing for the barrier design. Send contact info to info@acousticfields.com
Acoustics is not a term that is historically used for noise reduction but for noise direction. The old cathedrals would be built in such a way that when the choir sung, the sound would be directed to the people sitting in the pews and they would be able to easily hear and distinguish the words of the choir. Because of electric amplifiers and other sound equipment, buildings are not built with acoustics in mind. Instead, they just add more amplification which does not always solve the problem that is the result of the design. But then, in a multi-use building such as a Stadium designed for foot ball, soccer or basketball, you really don't want acoustics redirecting the noise to any one location. It's healthier to let it dissipate.
I do not see "acoustics in mind" in almost any usage that we work with. We have done 2 K venues down to one seat. I rarely see any thought about speech or music "intelligibility" at anything anymore. Churches build 2 K new, seat venues and then when they can only recognize 4 words out of 10, they seek a solution when they have no budget left, no space available to treat, and no knowledge of acoustics.
@@AcousticFields "I rarely see any thought about speech or music "intelligibility"" Which tells us that the architects that designed and built the grand cathedrals centuries ago, were more skilled and took more pride in their craft than modern day architects that rely on modern day technologies. I've read where people belittle and put down the intelligence of those from thousands of years ago claiming a greater intelligence when in fact, the ego trip of modern day man make them less intelligent.

That said; how much of that lack of thought is due to architect knowledge or the customer refusing to pay for what they really need?
For instance if a church has a serious sound management issue with lots of reverberation and intelligibility issues I would guess since Service Times are usually scheduled accustomed a specific schedule the measurements of Frequency and Amplitude would likely need to be measured during those specific time windows of usage. It’s those specific times when those issues are exacerbated and come into focus.
Reverberation times can be calculated to achieve low and high time windows by using software. There is no need today with the speed and storage of today's computers to take physical measurements for churches. Measurement dollars can go towards treatment costs. The time windows that today's software produces are quite efficient in determining treatment rates and levels along with the appropriate surface area coverages.
What are the frequency and amplitude (strength) of the noise issues? What day or night of the week are they the loudest? What is the load bearing requirements for your structure? Noise is a permanent build. There is no hanging panel that will stop noise.
Do you have any videos where you elaborate what you mean by "BTU wall" Do you just mean a layer of insulation between a double stud construction with a large air gap in between?
Which of the below-listed surfaces sounds best musically if left exposed? * Double Brick Wall (300mm) - no plaster * AAC (Aerated Autoclave Concrete Blocks - Hebel blocks 300mm) - no plaster * AAC as above + plaster 10-20mm * Concrete blocks (300mm) - no plaster
As with any trade, you must do your homework. We went through 8 carpenters to find one that would even show up on time with one project in the midwest.
Wow, I've been on this chanel for ever, and I'm kinda surprised by this content. I'm an acoustic engineer specialized in sound insulation for large scale theatres, and I don't agree with you especially on point 8 9 10 . It's funny to see how we think differently about those problems

It's already been done several times over. Type their name + vocal booth or home theater build, or studio, or listening room.
With the noise numbers, you can then design the barrier more accuately. Noise < 125 hz. is dealt with much differently than noise issues above 25 hz. That is just one variant that must be considered.

Thanks as always!

In the realm of acoustics, I would say 'measure 5 times - cut once. '
Yes, measure, measure, measure.

@@AcousticFields Thanks!
What do you think of viscoelastic drywall (like QuietRock)? Keeping people in apartments from hearing each other ...

he does... th-cam.com/video/kfj2DW-c_9Q/w-d-xo.html
Think of BTU wall as the material type that keeps your room warm or cold. Buiding insulation is a common material type for a BTU wall.
Which of the below-listed surfaces sounds best musically if left exposed?
* Double Brick Wall (300mm) - no plaster
* AAC (Aerated Autoclave Concrete Blocks - Hebel blocks 300mm) - no plaster
* AAC as above + plaster 10-20mm
* Concrete blocks (300mm) - no plaster
Concrete blocks filled with sand and glass beads or steel bearings. Interior - plaster at 2" thick minimum.
Sounds like the hardest part is finding a contractor that will do the job right.

What do you mean by “sound insulation”?
Please be specific. What is your question.
