The Audible Range of Sound
The audible range of sound refers to the range of frequencies that can be heard by the human ear. It is the range of frequencies that are perceived as sound and can be detected by the sensory organs in our ears.
The correct answer is B: 20 Hz to 20 kHz.
Explanation:
- The audible range of sound can be broken down into three main categories: low frequencies, mid frequencies, and high frequencies.
- Low frequencies are typically below 20 Hz and are often felt more than heard. Examples of low-frequency sounds include earthquakes or thunder.
- Mid frequencies range from 20 Hz to 2 kHz and are the most commonly heard sounds in our everyday lives. This includes the sounds of speech, music, and most environmental sounds.
- High frequencies range from 2 kHz to 20 kHz and are often associated with sounds like bird chirping or the high notes of a musical instrument.
- Above the audible range, there are ultrasonic frequencies (above 20 kHz) that are not detectable by the human ear.
- Similarly, below the audible range, there are infrasonic frequencies (below 20 Hz) that are also not perceived as sound by humans.
In conclusion, the audible range of sound for humans is from 20 Hz to 20 kHz, with frequencies below and above this range being either too low or too high to be heard.
