Sound is a fascinating subject to delve into, filled with numerous terminologies and concepts that students need to understand. One such concept is the
unit of sound, which is any unit used to measure acoustic sound. In this article, we aim to simplify and explain the units of sound for a better understanding.
Sound is a form of energy that propagates through different mediums such as liquid, air, or solid. This energy can be quantified, and the most commonly used SI unit of sound is the Decibel (dB).
This unit is primarily used to express the ratio of a particular physical property to another, usually on a logarithmic scale, known as the
Decibel Scale or DB Scale.
The unit can also be used to express different reference pressures or intensities. However, it's important to note that the sound intensity given in dB in the air will differ from dB in water.
Other Sound Units
Other units used to measure sound include:
sone – a unit of subjective loudness of sound
phon – a unit of perceived loudness level of sound
Hertz (Hz) – a unit of frequency of sound
watt per square meter (W/m2) – a unit of intensity of sound
These units are employed depending on the specific properties of sound being measured.
For instance, the intensity of sound is measured in watt per square meter (W/m2).
We hope this article has helped you understand the SI unit of sound and other units of sound. Stay tuned for more interesting articles and academic assistance.
