Document Summary
In other words, sensitivity varies across frequencies: the perceived loudness of a pure tone depends on the frequency, what happens for multiple tones. 1: reminder: metamers + additive mixing, adding two light sources together creates the perception of a new colour, same true for hearing, 2 different pure tones we perceive different sounds, but not always the case. Can happen when the frequency is relatively small. Started at two rough tones, then one rough sound, one sound with beating, turns to 1 sound: at some point, the sounds become two smooth tones (ex. Its related to: noise-induced hearing loss: caused by extended exposure to loud sounds (ex. If conductive: bone conductive air conduction ii: perception of ringing in the ears , causes: probably hair cell death, can be caused by tumors, drugs, exposure to noise, natural cell death. Inferior (just read the slide for this one, i didn"t get to.
