An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented...

frequency response of human hearing as charted in the equal-loudness contour, and has been compared to loudness compensation circuitry in that it increases the...

follows an equal-loudness contour (such as an inverted A-weighting curve). The result is that grey noise contains all frequencies with equal loudness, as opposed...

sensitivity above 2 kHz. The ATH is the lowest of the equal-loudness contours. Equal-loudness contours indicate the sound pressure level (dB SPL), over the...

they perceive sounds between 3,000 and 4,000 Hz, as shown in the equal-loudness contour. Because the frequency response of human hearing changes with amplitude...

Fletcher–Munson curves, which represented an early determination of the equal-loudness contour for human hearing. However, because decades of field experience...

considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for hearing loss usually involves an audiogram...

levels. The equal-loudness contours are a way of mapping the dB SPL of a pure tone to the perceived loudness level in phons (see loudness for details)...

quantization error is reduced by noise shaping the error according to an equal-loudness contour. This processing takes place in dedicated hardware inside the recording...

Fletcher–Munson equal-loudness contour. The B and C curves were intended for louder sounds (though they are less used) while the D curve is used in assessing loud aircraft...
