FAQ
4000 Hz questions
What note is 4000 Hz?
B7, 21 cents sharp, when A4 is 440 Hz.
Why publish 4000 Hz and not 4001 Hz?
Because this one sits on a band engineers solo, a tuning reference, or a hearing check. The tone generator already plays every frequency in between.

Keep a 4000 Hz tone at a conversation level. These pages can generate steady tones and noise, which fatigue your ears faster than music. If anything rings or feels uncomfortable, stop and turn the volume down.
