Why you need a sound level meter
A sound level meter is an essential tool for measuring and monitoring sound levels in various environments. Sound level meters protect people from several potential hazards and issues related to excessive noise. They offer hearing protection to avoid noise-induced hearing loss because prolonged exposure to high levels of noise can lead to permanent hearing damage.
Constant exposure to loud noise can cause stress and fatigue. Monitoring sound levels helps create quieter environments, which contributes to better overall health and well-being. It also enhances occupational safety for people working in spaces with loud machinery or equipment. Noise levels need to be monitored to ensure they do not exceed safe thresholds, helping protect workers from hearing loss.

Frequently asked questions
What is a sound level meter?
A sound level meter is a device used to measure the intensity of sound in an environment. It quantifies sound levels in decibels (dB), a logarithmic unit that expresses the ratio of a sound’s pressure to a reference pressure (usually the threshold of hearing).
How does a sound meter level work?
Sound level meters have a microphone that picks up sound and converts it into an electrical signal. This signal is processed to provide a reading of the sound level. These decibel meters are commonly used in various fields, including environmental noise assessment, workplace noise monitoring, audio system testing, and in research settings to ensure sound levels are within safe or acceptable limits.
Is there a difference between a sound meter level and a decibel meter?
There is no difference between a sound meter level and a decibel meter. A sound meter level and a decibel meter are essentially the same thing. Both terms refer to devices that measure the intensity of sound, typically in decibels (dB).
What is a standard sound level meter?
The current international standard for sound level meters is IEC 61672-1:2013. This standard is used to define the performance, accuracy and testing requirements for sound level meters. Compliance ensures that the decibel meter can reliably measure sound levels for regulatory and professional purposes.
What is a sound level meter calibration?
Sound level meter calibration is the process of adjusting and verifying the accuracy of a sound level meter to ensure that it provides accurate and reliable noise measurements. Calibrating a decibel meter usually involves comparing the device’s readings against a known reference level, often generated by a calibrator, to check and adjust the device’s accuracy.
