Web10 de feb. de 2024 · Psychoacoustics is the, at the most basic level, the manner in which our brains perceive sound. Various factors and variables affect the way in which we hear sounds including frequency, sound pressure level, subjective auditory variables and ear anatomy. In addition to these variables, there are a number of phenomena which are a … WebThe most direct physical correlate of loudness is sound intensity (or sound pressure) measured close to the eardrum. However, many other factors also influence the …

WebAlso called loudness level contours and the Fletcher-Munson curves. The curves are lowest in the range from 1 to 5 kHz, with a dip at 4 kHz, indicating that the ear is most sensitive … The perceived loudness at 1000 Hz is the reference point for defining the equal loudness curve through that point, so the numerical value of phons and dB is always the same at 1000 Hz. Finally, we could say that sound C at 65dB is the loudest of the four sounds since it shows the greatest displacement above the 60 phon curve.
