But below 40 dB, perceived loudness drops off more quickly; it takes less than a 10 dB reduction in sound pressure level below 40 dB in order for humans to perceive the loudness as having been cut in half. One sone is equal to about 1,000 Hz with a sound level about 40 decibels above a normal reference level. Meaning our perception of sound level is related to the frequency of the sound wave. To convert voltage or power gains to decibels, we can apply the following formulas: N dB = 20log10(AV) = 10log10(AP) N d B = 20 l o g 10 ( A V) = 10 l o g 10 ( A P) Further, the voltage and power gains of the system can be expressed as. In 1936, American psychologist Stanley Smith Stevens proposed a new unit Sones when studying psychoacoustic.

High frequency hearing loss quite often occurs in people as they age. For pure tones at much higher or lower frequency, loudness in phon will be less than sound pressure level in dB because hearing is less sensitive as you move away from the neighborhood of 1 kHz. If a 125 Hertz tone is 47 phons, it is as loud as a 1000 Hertz tone at 47 decibels. We recommend the following: first, think about the max amount of noise that you would be comfortable with.
