Question

In a loudness curve, any frequency along the curve has a perceived loudness of ______, regardless of the actual physical measure in dB.

a) 50 phons
b) 40 sones
c) 60 decibels
d) 30 hertz

Answer 1

In a loudness curve, any frequency along the curve has a perceived loudness of 40 phons, regardless of the actual physical measure in dB.

Step-by-step explanation:

In a loudness curve, any frequency along the curve has a perceived loudness of 40 phons, regardless of the actual physical measure in dB. The loudness level in phons is a unit of perception, while dB is a unit of physical intensity. The equal-loudness curves indicate that for each frequency, any point on the curve corresponds to the same perceived loudness level.
