Question

Quizplus · Accepted Answer

The human ear is most sensitive to sounds in the range of 1,000 to 5,000 Hz, which means that a speaker producing sound at 1,000 Hz would sound the loudest. Additionally, 30 W is not a lot of power for a speaker, so it is unlikely that it can produce very loud sound at lower frequencies like 50 or 100 Hz.
