Equal loudness contour calculator

An equal-loudness contour is a measure of sound pressure (dB SPL), over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon, and is arrived at by reference to equal-loudness . Auto Calculators & Various References Links Guest-Book-Sign-In Guest-Log HOME We have collected many auto calculators that may simplify sometimes complex design task. Many auto calculators are created to specific application. Some auto calculators have been created within a school project. The perceived loudness at 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 Hz. Finally, we could say that sound C at 65dB is the loudest of the four sounds since it .
