The ear-resetting scan tone

According to French ENT specialist Dr. Alfred Tomatis (1920-2001), abilities such as attention and learning can be improved by retraining the ear to listen to high-frequency sounds. This type of sound indeed provides a good stimulus to the brain's neurons. According to Dr Tomatis, once the ear is retrained - typically after a series of listening sessions extending over a couple of weeks - individuals concentrate better, and learn more efficiently.

Low frequency sounds tend to achieve the opposite effect, such as inducing relaxation and drowsiness: they may not be suited to improving your learning abilities, but are definitely worth trying when suffering from anxiety and insomnia.

This generator covers the entire audible spectrum: left sliders are for the lower frequencies and relaxation; right sliders are associated with the higher frequencies and alertness. Set the sliders according to these generic guidelines, adjust them to a position that intuitively feels right for you personally, then put more emphasis - only slightly - to the lowest slider(s) if you are about to experiment with relaxation, or the highest one(s) if you want to retrain your listening skills according to the Tomatis' theory. In this latter case, get into the habit of listening to your custom sound regularly over a couple of days, by continuing to emphasize the highest sliders as the training progresses.

Calibrated Output

This sound generator is calibrated and outputs a pink-like spectrum when the sliders are horizontally aligned. Calibration is unique to this website, and can be used to compensate for your own hearing, audio equipment, and listening environment deficiencies: follow our Calibration Procedure once, then access Your Hearing Curve from the right column.

  Wow! I just used my hearing curve on this and it sounds great! 10/10 Awesome!

  I use my hearing calibration, and this is great for calming myself so I can study: it helps suppress my anxiety and gives my mind the "space" to focus. A++ sound generator.

  This is some good stuff! My ears can really scream. 20 minutes of listening to my custom sound and everything is all well. Erniej

  I suffer from high frequency tinnitus, which makes me feel 'spaced out,' dizzy and unable to concentrate. The high tones of Aural Scan break up the continuous tinnitus note and after an hour or so I can think clearly and concentrate on my day. Far better than any music or 'White, Pink, Brown Noise' generators which don't seem to work for me. Aural Scan is brilliant!

  Homework. JOY! Not. This helps me focus and uh makes my brain melt every once and a while. THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU !!! - Blurryface

  Seconding the observation that this generator will make your cat wig out! A strange glittering mix of tones both soothing and stimulating that somehow magically fades into the background and keeps you focused -- but pet owners might best enjoy it with headphones.

  This is fascinating! I just turned on Aural Scan and our cat woke up and ran to the computer's speakers, clearly attracted to the sound. She purred loudly while nuzzling her face into the speaker grill. Minutes later, I switched the sound output to a bluetooth speaker across the room and the cat raced across the room to that speaker, displaying the same fascination. Hmmmmm.

  Headache gone and I can focus. I won't miss my deadline! Thank you, thank you, thank you.

  It certainly sounds like something in the Portal games. This can certainly fit.

  I've got three of these running at once, overlapping. It took about thirty seconds to wake me up and get me focused - when it would take several hours, lots of caffeine, and physical activity to do the same normally.

  High concentration! Great for reading long books or even just small school passages!

  Yay! I can concentrate better now! Start here and animate it. I feel as if I can read this entire book of poems without stressing or forgetting what I read! Thank you > . < Now... I must go make Ramen and finish my anime ;u; But I shall use this for school work, so I don't get all jittery and anxious about nothing!

  Done right, it makes you feel relaxed, but also eager to learn.

  Meditated to this. Had the best meditation I've ever experienced.

  I've been trying this out for studying. I feel it might be helping, although I also find grey noise helps get me into my own world!

  I'm calibrating my hearing curve and using that for this and mixing it with other calibrated generators and it feels like a super peak dose of adderal on my best day against my adhd. SUPER LAZER FOCUSED LIKE NO OTHER. For best results, recalibrate when the noise becomes annoying because that means that your perceptual curve has changed and the played curve no longer matches.

  It kinda tickles in my brain :o)

  That feels so so nice c:

  Thank you so much... I feel so good after hearing this..

  I never had concentration or focus problems when I was younger, but now I do. I had been procrastinating terribly for weeks on drafting a business plan for an international nonprofit. I wanted to see if one of your sound generators could help, so I tried Aural Scan. Within just two hours, I had written the entire document and it was much sharper and more astute than I imagined it could be.

  I feel like I just completed my transformation into a super saiyin after listening to this.

  Thanks a lot. I nearly failed this exam but this and a night of learning and everything went well. I'm so happy this exists ^-^

  Thank you Dr. Pigeon for this wonderful site. Doug

  There is something very soothing about these sounds. After I stopped listening, I felt a little tingling sensation in my head. Stimulated. Awesome.

  A very stimulating tone. It's great while reading textbooks and I always use this to study since it keeps me alert and focused. It's also such a fun and interesting tone that listening to it is motivating and puts me in a good mood. Studying and reading text books in a good mood is so much easier.

  A GIANT THANK YOU Stéphane. I thought I was failing at a school assignment, but I remembered somehow about Aural Scan, and how it can help you. I gave it a try, I was a little skeptical at first, but I tried it anyway when I studied for the assignment, and IT WORKED. I learned pretty much 80%, even the teacher was amazed how much I learned in a single day. Again Stéphane, thank YOU.

  My personal calibrated curve - it keeps you on the line between relaxed and alert!

  Wow. This was amazing! Almost immediately did I start focusing on my homework, and let me tell you I'm a huge procrastinator! This really helped and I thank you so much for it. Keep up the fantastic work! ^_^

  I have so many problems staying focused and this one helps the most of any on this site, I really like it!

  Sounds like something from Portal 2.

  I am suddenly so focused, I love this. ;)

  I found my new favorite! Wow, I have been listening for hours. At first I thought it would break my concentration, but rather it made me super focused and energetic toward my work! Amazing!!

  After listening for just a few minutes I noticed a reduction in my tinnitus :o Great to listen to while working, while effectively cancelling out the noises in my head!

  I don't really understand the science behind this one (could be placebo effect), but I can listen to Aural Scan for hours at a time and love how focused I feel. Never gets old.

  ← The Chill Machine

  ← Its very relaxing and alerting, and it helps me focus on my work.

  Sorta sounds like a song. I like it.

  Wow. This is kind of awesome :D (high-frequency settings)

  Great to relax to!!!

  This is very relaxing, and if you put it on animate, then it's pretty good helping me to unwind and relax some! Pretty good for focus too, depending on the person. The background noise is perfect for a silent house or classroom!

  Soft and smoothing. Helps me focus when I'm having trouble to and helps me sleep at night! Amazing soundboard.

  Layer this over Twilight (set to your personal calibration is best), put both in the Meditation setting, and kick back and relax! They'll both change and wrap around each other in the most beautiful of ways.

  This really offered some sort of 'thinking noise' for me. I have trouble concentrating on one thing at a time, this really helps me stay on task.

  Aural scan is sacred sound! it positively affects us without even realizing.

  Thank you for making a brainwave sound that's safe for those with seizures to listen to! Mine are induced by stress and understandably get worse when I'm cramming, but the high pitched noise keeps me focused when I need it most c:

  I was having a very bad time concentrating on my work but this sound worked like a magic on me! Thank you!

  Hmmm... this works!

  Set it to drowsy, duplicate the tab and let that one go on white... so nice! Thank you Mr. Pigeon!

  This sound has an angelic feel to it, and it is very relaxing. My stomach was in pain and my mind was stressed. Now both my stomach and mind are at an angelic peace thanks to this site and sound!(:

  I had this huge school assignment I had to complete in one night. I was dangerously close to falling asleep. The other noises on this website did not help and I was discouraged until I listened to this noise. After listening for a little bit, I felt significantly more awake and was able to concentrate very well. I highly recommend the "Alert" setting. It really did help! Thank you so much!

  Welcome to the Grid, Program.

  I have an extremely difficult time focusing on my schoolwork (especially when I'm tired or bored of it). However, this sound, placebo or not, is giving me a refreshing kick of concentration. Thanks for this highly innovative sound!

  I don't know if it's my imagination or science but this high frequency really works I'm feeling more alert and I'm learning faster than normal when playing this high frequencies in the background. Thank you so much for this site, it has helped me a lot in many ways.

  Very refreshing take on the subject of sound to amp attention and learning capacity!

  This is really intense! Totally not what I was expecting, but I love it! It makes me feel relaxed yet focused, without getting annoying or boring. Very cool.

  This is a combination of low and high frequencies. As someone with anxiety, the high frequencies alone make me nervous and jittery. But with low frequencies mixed in, they work together to make me more alert and focused without giving me jitters. Starting here and clicking 'animate' gives me inspiration for writing for hours.

  Wonderful sound! It helps me get on track when I have something to work on! Very sci-fi!

  I found this sound half an hour before the end of my workday - suddenly it feels as if I could put in another 9 hours!

  I really like it! It's calming and futuristic. Even though I'm not that good with high noises, this somehow makes me easier to focus.

  It helped me when I had a headache. Thanks a lot! ^_^
