WebJul 1, 1974 · The well-known phon curves, or equal loudness contours, are carefully plotted to minimise the risk that they might be regarded as having anything to say about the sone scale or loudness function. But the implications are there nevertheless, as we have seen.

We can hear some sounds at intensity levels below 0 dB. For example, a 3-dB, 5000-Hz sound is audible, because it lies above the 0-phon curve. The loudness curves all have dips in them between about 2000 and 5000 Hz. These dips mean the ear is most sensitive to frequencies in that range. http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/eqloud.html theories of communication tuckman

However, research in the 1960s demonstrated that determinations of equal-loudness made using pure tones are not directly relevant to our perception of noise.

Thus, the 100-phon equal loudness is less variation for low, medium, and high-frequency sound pressure levels. That means human ears hear more music at higher volumes instead of lower volumes. In turn, cranked-up music is also perceived to …

WebThe use of phons for the measurement of sound loudness entails using several equal loudness curves, which get determined experimentally (Oberfeld, 2007). The experimental procedure for the determination of the equal loudness curves involves, first, subjecting individuals to a 1 kHz sound at 60 dB (loudness of 60 phons). WebEach curve is labeled with its loudness in phons. Any sound along a given curve will be perceived as equally loud by the average person. The curves were determined by having large numbers of people compare the loudness of sounds at different frequencies and sound intensity levels.
