Question

unit for describing loundness is​

Answer 1

Answer:

PHON A unit used to describe the LOUDNESS LEVEL of a given sound or noise. The system is based on EQUAL LOUDNESS CONTOURS, where 0 phons at 1,000 Hz is set at 0 decibels, the THRESHOLD OF HEARING at that frequency (see graph). The hearing threshold of 0 phons then lies along the lowest equal loudness contour.

Answer 2

Answer:

Sone, unit of loudness. ... One sone is arbitrarily set equal to the loudness of a 1,000-hertz tone at a sound level of 40 decibels above the standard reference level (i.e., the minimum audible threshold). A sound with a loudness of four sones is one that listeners perceive to be four times as loud as the reference sound.
