PCE Instruments
A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed. Here at PCE Instruments, we offer two types or classes assigned to decibel meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 decibel meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used.

General Tools & Instruments
Real-time applications for our sound level meters include sound-system setups, music recording, and measurement of the noise produced by a machine or vehicle or typical of an environment. Data logging sound level meters such as our DSM402SD, DSM403SD and DSM20 provide the documentation needed to prove compliance with regulatory limits on noise exposure in public and at work.
