Sound measurement refers to the process of quantifying sound levels, typically using a device called a sound level meter. This device measures sound intensity in decibels (dB), which is a logarithmic unit that expresses the ratio of a particular sound pressure to a reference level. Accurate sound measurement is essential in various fields, including acoustics, environmental science, and engineering. It helps assess noise pollution, design soundproof spaces, and ensure compliance with regulations. Understanding sound levels can also aid in protecting hearing health and improving overall sound quality in different environments.
