"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. " - Hearing curve percieved loudness

WebIf you plot perceived loudness against dB, you get a function that is essentially linear, maybe even scooping up a bit. However, when you plot perceived loudness against the amplitude of the pressure wave, or even against intensity (pressure squared), you see that our perception of loudness is compressive: the louder a sound is, the bigger the change … WebTo convert the digital noise to audible white noise, a 3-pole low-pass Butterworth filter with a cut-off frequency at 40 kHz and a gain of 1 is used. For simplicity, you may want to assume a perfect low-pass filter with a cut-off at 40 kHz. For pink noise, a 3 dB/oct. filter is used with a gain of 1 at 100 Hz.

Web4 de jul. de 2024 · Loudness equalization simulates human hearing to accurately measure the loudness—as opposed to intensity—of an audio source. It then uses dynamic gain adjustment to keep the loudness of different sources more nearly constant. Loudness equalization can thus affect both dynamic range and peak loudness.
