In your app, the "ultrasonic" signal is still audible to me. On that youtube video, I stop hearing stuff around 17,5kHz.

- brian-armstrong 11y agoPerhaps I should have labeled it author-ultrasonic ;) I haven't really found much data about the distribution of hearing capacities, so it's hard to tune this to be truly ultrasonic. The average sound equipment starts getting really distorted at around 19kHz, which doesn't leave much space above 17,5, unfortunately. Thanks for trying my demo!
- Nadya 11y agoYoutube compresses audio above 17kHz so it shouldn't be audible at all past that. Note: It's at some random value that isn't exactly 17kHz, I think it's 17.6kHz? So it no longer making sound for you at 17.5kHz could be because of that, not because of your hearing.
