Human perception of noise: it is a theory in psychology that our perception of objects, both visual and auditory, is determined by certain principles. The human perception of loudness aim: the aim of the experiment was to discover the difference between loudness and sound pressure level, gain knowledge of typical sound level values in common environments and to be able to make rough estimations of what sound level measurements could be in different places. Research characterizing the human hearing range perception of low frequencies to that loudness feature the loudness control is simply intended.

Humans perception of loudness is physiologically different across the audible frequency range (around 20–22,000 hz) simply said, sounds at higher frequencies tend to be perceived as louder by human, until certain level. This post looks at loudness and sharpness, two important psychoacoustic metricsbecause they have to do with human perception, these factors are.
