Vera_Pavlovna [14]

Answer: B.  Wave A is louder than Wave B.

Explanation: The loudness of sound is measured in unit called decibels (dB).

A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.

Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.

Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.
