Answers
Answer:
In simple terms, sound is vibration. The complex internal structure of our ears can respond to the waves produced by vibration, whether in the form of bass drum or an acoustic guitar.
When an instrument produces vibrations, it creates oscillating sound waves. Some of these waves are audible to humans, while others are very deep or high-pitched, and fall outside the human range of hearing.
A variety of metrics are used to measure sound’s intensity, volume and pitch. The pitch of sound is measures in hertz. One hertz (Hz) refers to the complete cycle of sound waves per second. Thus, 5,000Hz is equal to 5,000 cycles per second.
The human ear can generally perceive sound between 20Hz and 20,000Hz. Animals can often hear sound that humans can’t. For example, dogs can hear sounds at very high frequencies – often above 20,000Hz – but cannot hear low frequency sounds.
