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 … Web12 dec. 2008 · For humans, the reference level is the “threshold of hearing”. This means that we always talk about decibels in the positive sense, such as 50dB or 60dB; we don’t say that some noise is -20dB. To futher confuse matters, humans hear “weighted” noise levels. It is “weighted” because our ears do not treat all frequencies the same.
