FAQ

300 Hz questions

What note is 300 Hz?

D4, 37 cents sharp, when A4 is 440 Hz.

Why publish 300 Hz and not 301 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 300 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.
