Question

Quizplus · Accepted Answer

The range of human hearing is typically considered to be from 20 cycles per second (or 20 Hz) to 20,000 cycles per second (or 20 kHz). Therefore, option C is the correct answer. Options A and B are incorrect because decibels (dB) are a measure of sound intensity, not frequency. Option D is incorrect because the range of human hearing is not typically measured in cycles per second, but rather in hertz (Hz).
