Music Glossary: psychoacoustics

Psychoacoustic frequency scale dividing the spectrum into 24 critical bands. more

Frequency bandwidths of the auditory system where masking interactions are strongest; basis for Bark/ERB scales. more

Phon/sone curves mapping SPL needed at different frequencies for equal perceived loudness (Fletcher–Munson/ISO 226). more

Equivalent Rectangular Bandwidth model describing auditory filter widths across frequency. more

When a strong sound makes nearby frequencies less audible; temporal masking affects sounds before/after a masker. more

DSP technique that spectrally redistributes quantization noise to less audible bands. more

Tone color or quality that distinguishes instruments/voices even at the same pitch and loudness. more
