Convert decibel (amplitude)s to semitones
How to convert decibel (amplitude)s to semitones
Convert through a plain ratio: decibel (amplitude) → ratio → semitone. Logarithmic units cannot be converted by multiplying alone.
Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
Semitone: Twelve-tone equal temperament: each semitone is the twelfth root of two.
