I wish I knew of binaural beats before. Somehow this makes my concentration more focused and things seem manageable all of a sudden. I thought, my concentration was gone for good but now I feel much better. Thank you!
Literal god send. My mind has been going haywire and I've been procrastinating so much for the past 5 days. This is the first time this week that im actually enjoying and focused on studying all thanks to these beats. Gonna do one more 30 min before going to 60 min then hopefully 90 min
It's just a matter of practice, as you get used to studying for a certain duration, you can advance slowly till you reach the sweet spot. Personally I have gotten used to the 90min one and can feel myself getting in the zone more and more easily everytime. I do two 90min sessions per day and it has probably been the most worthy time investment I have ever done.

Wow, thank you! managed to finish making a paper while listening to this. I didn't even notice the time! I just finished my paper right at the time that it was finishing too. So cool! Thank you!
Thanks bro... Finished my homework just because of this... Best for revising notes because it puts you into deep thinking state and better recalling of concepts 😇😇😊😊
i must say, i spent weeks, months, if not years finding the right binaural tracks. at least, right for me. there are lots of options out there, but for me, these Jody Hatton tracks are the best. hands down! Jody, are these study tracks good to listen to with Mozart playing at the same time? or do you think it diminishes their effect? thanks in advance!
@@kierenkane7516 I’m not sure tbh… I’ve noticed that with the classical music, every now and again, the tones of the notes of certain instruments harmonize and do something to the binaural beat. I would say no music other than classical and even then maybe? Curious to know what Jody says/thinks…
@@kuzkateco You are simply making the perceived waveform more complex, which can actually help to mask the binaural beat in a way that makes it more subconscious and more effective. We did human trials at Kings College London where I measured brainwave synchronization, or entrainment, to binaural beat rates using an EEG machine. Subjects were given a GUI that allowed them to set levels on background music. Those who set their music levels with a higher amplitude than the binaural beating experienced quicker brainwave synchronization to the external stimulus of the binaural beat rate. Binaural beats will absolutely “work” when listening to simultaneous background music. “The perception of a binaural beat is said to be heightened by the addition of masking noise to the carrier signal (Oster 1973), so white or pink noise is often used as background. Practices such as humming, toning, breathing exercises, autogenic training, and/or biofeedback can also be used to interrupt the homeostasis of subjects resistant to the effects of binaural beats (Tart 1975).” Ultimately though, it's up to you!
Hi Jody! Would it be possible to upload a video of a 45min study session as well? Your videos help me so much! Thank you for your work. It's been helping me a lot!
Often times, when reading books (non-fiction books) my mind starts wandering and I read on autopilot without retaining the material. Do you think these videos can help me keep my focus while reading?
Can you please an audio for driving learning nervousness ..i mean i have tried 8 times ,and normally i drive very good but when in Learning Licence ,i did blunder.please help
imm a big fan of you! being studying, sleeping awakening with your videos and i loved themm. i wonder if you could make some binaural for meditate and activate chakras, pineal gland and that kind stuff. Sorry my english, greetings and congratulations from Chile!
I'm a little bit confused on the volume I should use, I know it says 20%-40% but even 20% feels like it's too much some times, has anyone found a rule of thumb like "you should barely be hearing the wobbling sound" or something like that ?
HI , Thank you Very much for this Beats , As we are using this and having good result on kids. Thank you for your mail and given all details and suggestion.
Lectures, no problem! (If music, heavy bass may create interference or additional unintended beats. If you have the ability, I'd filter out anything below 200 Hz to be safe.)
Thank you so much for sharing Jody. I'm trying this "shorter" version of 30 mins, and noticing a "new" beat. Before I never noticied. Is this just me, the audio or it is part of the session? The beat I mention is like soft tap in the table. Occours every 1-2 seconds and its a sequence of 3 taps.
There definitely shouldn't be any tapping sounds. Try rebooting your device, using a different device, different headphones, disabling any filters, enhancers, bass boost... 🙂
Noise cancelling isn't the goal here. You'll have distractions everywhere but these binaurals will help your brain to focus more efficiently. Hope this helps 👍
I used this yesterday for about an hour and a half, seemed to really help with concentration. Today, however, after the first 15 minutes I suddenly felt a little nauseous. Kept on for another 5 minutes but, since it was getting worse, I quit. Anyone else had an experience like this?
Binural beats are a powerful stimulation to the brain and sometimes you need to "condition" yourself a bit. If you started with 90 minutes you might have over trained. Give yourself a few days off and then start up again . I tend to use a pomodoro timer so I take breaks every 30 minutes and give my brain a break. Also, I found for me I listen at a low volume... a little above auditory threshold.
@@anapaularuhe It was pretty low - about half the volume of what I’ll listen to an ordinary video on. But I’ll try it much lower next time. Thanks for your comment!
3 ปีที่แล้ว +2
To me, the perfect volume is 4 out of 100, so it really depends on your preference and how you feel. I also get headaches or feel like my intracranial pressure goes up if I listen too much of these beats. You need to find the right time/volume for you! This way they help a lot ;)
Thank you Jody for your beautiful job... Many blessings to you and your smart thinking.. i just discovered your Chanel and i love it.. i am using the one for study 30 minutes, is there a longer one? Or should I take breaks and repeat?
Hey, thanks for sharing! Glad to hear you’re liking the channel! Here is a 60-minute focus/study track: th-cam.com/video/vrLsNlZOF1o/w-d-xo.html As well as a 90-minute one: th-cam.com/video/Dq-h8LIe6II/w-d-xo.html And yes to taking many breaks throughout the day!
Could you do a version of binaural beats to work? I found out that at least it looks like that beta binaural beats works best for me when it comes about work.
Hi there Mr Hatton! I think that it can be useful to use lower range of Hz ( 8-9 Hz) just above THETA than 10-11 Hz (used here). Low Hz are linked to deep concentration, aren't they? In any case, the video is simply great :)
I mean, you can have side effects on your ears (meaning your ear canal can be echoing the binaural beats even after you turn it off for a period of time, similarly when you have air stuck there and you lose temporarily some acoustic definition, you know? So I lost some hearing while having the echoes hearing accidentally on 70%. I felt like that but it passed after a few hours). Mainly it can do more harm to your brain in the sense of BAD headaches if you abuse the binaural stimulation regarding time (overextending) and volume (too high) of the track because your brain can only sustain a frequency for a period of time (not including the sleeping ones because they improve your rest even though lasting for 8hours on the right volume). On a regular basis, the binaural stimulation (meaning alpha-focused studying tracks) as Jordan recommends is max 1h30 at 20% volume (maybe 30% if you're in a loud environment) with breaks to let your brain reset its frequencies. I hear at 18% on YT w/ my overall Windows volume on 50%.
Hi, I've used this binaural beats for the first time for around 30 min, with the second lowest volume on TH-cam, and 15% volume on laptop. After finishing this I began to hear ringing sound in my ears and it lasted for two days now, is that normal?
@@Santiago-ke7yj thanks for the heads up, actually I've stopped it after the very first session, I haven't been listening to it since. There's still ringing sound but it's lesser now
@Sarah Collins it does now, it lasted around more than a week and it's reduced significantly, it might differ for every person, but it's just not for me
I played this over a 40-60 Hz White noise, on 20% volume, and I find it more helpful for Mathematics and numerical, any explanation for it? or is it just person to person?
White noise should have all the frequencies, not just 40-60... also, playing another track at the same time will likely create additional unintended beats.
Unfortunately, it's physically impossible to hear a "binaural" beat without headphones. If you listen with speakers, you get an acoustic (or monaural) beat. Learn more here: bit.ly/bineye1what
Does relaxing to the level where my heart beat drops from about 70-80 to 40-50 while listening to your super nap videos, it's a sign that I'm at alpha state?
if you use the to focus while doing yoga or exercising then ya, just listening to them wouldn't do any thing as far as i know, though i would argue listening to them (or any relaxing music)might reduce stress which will help in weight lose and also reduces craving.
like what @@oximas-oe9vf said, binaural beats will not be effective for weight loss without exercising. But if you think that weight loss is that easy then clearly you haven't even tried. Weight loss takes time and if you are not bothered to commit any time to developing your health then you won't be able to do anything

"barely hear the wobble" is a typical binaural beats instruction I think, so probably not a bad place to start.
Hey Jody!
Is it possible to get this music on SPOTIFY ?
nah, but you can download this. link's in the description
Do binaural beats work if you have unilateral hearing loss (in other words, you are deaf in one ear but not the other)?
in this case you should try "isochronic tones"
