Decibel Meters
-
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.

Sound Level Meters & Calibrators
-
A sound level meter, also known as sound pressure level (SPL), decibel (DB) meter, noise meter or noise dosimeter is mainly used for measuring sounds travelling through air. It is used to test noise or sound levels by evaluating sound pressure. It uses a microphone to capture sound and the sound is then evaluated in the device. It is commonly used to prevent loud noises to create a better work environment.

SPL Calibrator -124 dBSPL @ 1 kHz
511ES124
-
The 511ES124 is designed to provide 124 dBSPL at 1 kHz to meet the needs of the low sensitivity microphones found in many high SPL measurement applications. The microphones used in Car Stereo competitions like dB Drag racing, IASCA, and USAC have had their sensitivities reduced to the point where 94 dBSPL may no longer be adequate for calibration.

Sound Level Meters
HD 8701
-
The sound level meter HD 8701 is a portable instrument, easy and quick to use, suitable for measuring industrial and civil noise levels. The noise levels can be read easily in dB (A) on the large liquid crystal display which also shows all the information concerning the mode of operation of the instrument. One second after switching on and with a resolution of 0.1 dB, the digital reading gives the continuously updated value of the RMS sound pressure level, with a type A frequency weighting. The single range from 30 to 130 dB further simplifies the use of the instrument, as the user does not have to change scale.

Sound Level Meters
-
A sound level 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 sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.
