They are typically used by safety professionals to monitor conditions and the observance of recommended exposure limits (RELs). However, in certain cases, sound level meters used for continuous monitoring of noise levels in a particular environment can be permanently installed.ĭecibel meters are used for measuring environmental, industrial, or machine noise levels. Some decibel meters also show additional acoustic parameters such as the equivalent continuous sound level (Leq).ĭecibel meters are usually portable and run on batteries.
These measured noise levels are expressed in decibels (dB) and displayed on the instrument’s screen. The decibel meter then uses signal processing to apply frequency and time weightings to the signal according to international standards.Ī decibel meter responds to sound much like a human ear to give objective acoustic measurements of noise levels in a certain environment. The mic captures sound pressure deviations and converts them into an electrical signal that is made stronger by a preamplifier. Other common names include noise meter and sound level meter.Ī decibel meter uses a microphone to capture sound. For this reason, the decibel meter is also known as a sound pressure level (SPL) meter. What Is a Decibel Meter?Ī decibel meter is a sound pressure measuring instrument for standardized measurements that uses the decibel scale. In this article, we’re going to shed light on what a decibel meter is and how to properly use it. This sound measurement instrument is gaining popularity and has many people asking what it’s for and how to use a sound level meter. Have you ever wondered what a sound level meter is? You are not alone.
