The number of pressure variations per second is called the frequency of sound, and is measured in Hertz (Hz) which is defined as cycles per second. The higher the frequency, the more high-pitched a sound is perceived.
Can sound be measured?
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Decibels (dBDecibels (dBIt is usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the logarithmic decibel (dB) units ("dB gain").https://en.wikipedia.org › wiki › Gain_(electronics)Gain (electronics) - Wikipedia) are named in honor of Alexander Graham Bell, the inventor of both the telephone and the audiometer. An audiometer is a device that measures how well a person can hear certain sounds.Jan 28, 2019
