Webthe minimum distinguishable frequency that a human ear can hear is not an absolute value in hertz but a percentage of the the frequency in question. For example, to go from C to C# in the first octave C0 is ~ 1Hz, in C1 is ~ 2Hz,..., in C8 is 248.91Hz. The percentage difference from C to C# is 5.95% +-0.02%, and this is constant throughout. 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 …

WebHuman hearing involves multiple parts like the eardrums and cochlea to translate sound vibrations. Meanwhile, bees use vibro-detecting organs in their legs and antennae to “hear” sound. Sources ResearchGate Recommended Posts Honey Bees Honey Bee Colonies WebTo the human ear, an increase in frequency is perceived as a higher pitched sound, while a decrease in frequency is perceived as a lower pitched sound. Humans generally hear sound waves whose frequencies are between 20 and 20,000 Hz. Below 20 Hz, sounds are referred to as infrasonic, and above 20,000 Hz as ultrasonic. in absential deportation hearing
