What is the unit of perceived loudness equal to 40 phons?
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). 40 Phons = 1 Sone. Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness"
What is the purpose of the loudness level unit the 'phon'?
The 'phon' unit is used to measure subjective loudness perception, which is how loud a sound is perceived by the human ear. It is based on the equal loudness contours at different frequencies and is used to quantify the perceived loudness level of a sound.
What are sones?
Sones are a unit of perceived loudness developed by Stanley Smith Stevens in 1936. In acoustics, loudness is the subjective perception of sound pressure. According to Stevens' definition, the sone is equivalent to 40 phons, which is defined as the loudness level NL of a 1 kHz tone at 40 dB SPL. The number of sones to a phon was chosen so that a doubling of the number of sones sounds to the human ear like a doubling of the loudness, which also corresponds to increasing the sound pressure level by 10 dB.
What is louder 2.5 sones or 4.0 sones?
You can convert the loudness in sones to the loudness level in phons. 4 sones equals 60 phons. Scroll down to related links and read "Correlation between sones und phons".
What is 8.5 sones in db?
You can convert the loudness in sones to the loudness level in phons. 8.5 sones equals 70.9 phons. The convertion from sone to dB is only a guess. Scroll down to related links and read "Correlation between sones und phons".

What unit of perceived loudness is equal to forty phons?
The loudness of 1 sone equals the loudness level of 40 phons (at 1 kHz). Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing.
What is the unit of relative loudness?
There are the loudness level LN in phons and the loudness N in sonesScroll down to related links and look for more on correlation between sones and phons.
