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.

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.

CAD Tool
Sabin
Sabin is a powerful CAD tool for room acoustics engineers. Based on statistical calculations, it determines the acoustical parameters of a user defined room, such as the reverberation time T60, the sound pressure level, and the RASTI as a measure of speech intelligibility. These parameters are updated dynamically, while the user is changing simulated sound sources and absorbing materials.
