Amplitude Scaling Invariance




Although seemingly trivial, it may be non-trivial for the brain to implement. In particular louder sounds actually activate a larger set of sensory cells in the Organ Of Corti , so it is non-trivial for the brain to recognise the equivalence of softer and louder versions of the same sound.

One aspect of music perception which is not invariant under amplitude scaling is that our level of enjoyment of music that we like is increased when that music is played more loudly. A common consequence of this preference is deafness caused by listening to over-loud music.
