The subjective unit of loudness of sound equivalent to 1 db at 1000 hz is called phon.
The unit of loudness level, called the phon. One phon is the loudness level of an pure tone of 1000 Hz whose sound intensity level is 1 dB; 1 phon is equivalent to 1 dB at 1000 Hz. The quantity of phones of any given sound is equivalent to the quantity of decibels of an pure 1,000 Hz tone judged to be of the same loudness as the original tone.
It is called phon.
Decibel is the unit used for the loudness.
The loudness of sound is estimated in units called decibels (dB). A decibel unit communicates the relative force of sounds on a scale from zero for the normal slightest discernible sound to around 100 dB, which is near the level most people find uncomfortably loud.
The real estimation is rms pressure, pascals, yet it is typically communicated in decibels re a reference weight of 20 µPa.
Sound is the annoyances in climatic pressure that fall inside the scope of human hearing.
