D) None of the above

Question

Quizplus · Accepted Answer

The loudness button is designed to boost the low frequency sounds which are perceived as less loud at lower amplitudes compared to higher frequency sounds. Therefore, option B is the correct choice as it explains the purpose of the loudness button. Options A and C relate to other aspects of sound perception and are not related to the function of the loudness button. Option D is incorrect as the question specifically asks about the purpose of the loudness button.
