FAQ

2500 Hz questions

What note is 2500 Hz?

D♯7, 8 cents sharp, when A4 is 440 Hz.

Why publish 2500 Hz and not 2501 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.

How loud should I listen?

Keep a 2500 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.
