Web21 dec. 2024 · $\begingroup$ i think this is definitely a physics question. The hearing nerve [and/or brain] can only process 20-20khz frequency, based on the ear drum being a physical vibrating membrane. If the frequency is at some ultra level (above 20khz) it is the amplitude (above 120dB) where the sound [pressure] wave will rupture your ear drum you'll just … Web24 jan. 2015 · As has been mentioned in other answers, the folds of your ear generate interference patterns. The effect of this is to "color" the sound, raising the volume of some frequencies and damping others. These interference patterns are different from different directions, so sounds from different directions get colored differently. hg rata dainese
