About Tone Generator
Online Tone Generator plays a constant tone at a selected frequency. It supports adjusting frequency by slider, arrow keys and small increments, halving or doubling the frequency, switching between sine, square, triangle and sawtooth waves, and mixing tones by opening multiple browser tabs.
The site warns that playing tones at extreme volumes can damage hearing or speakers, noting that sounds below 20 Hz and above 10,000 Hz are hard to hear. It also states the generator is not a medical device and guarantees nothing.
