What a calibrator does...

Use a handheld acoustic calibrator (also known as a sound level calibrator) to produce a known sound pressure level at a known frequency. This level can then be used to adjust your sound measuring equipment to measure more accurately, since microphone performance can vary with weather conditions. This process, commonly known as field calibration or acoustic calibration, is typically performed both before and after every measurement.

Uncompromising Accuracy & Reliability

Uncompromising Accuracy & Reliability

The Larson Davis CAL1150 is the definitive Class 2 calibrator. Designed to meet the stringent requirements of UK noise regulations and IEC 60942:2017 standards, its dual output levels (94 dB and 114 dB at 1 kHz)

It's robust, portable design is built for the rigours of UK field environments, providing a dependable tool that streamlines your workflow and guarantees the integrity of your acoustic measurements, project after project.

Lightweight & Low Cost

CAL1150 is a lower cost option for calibration of Class 2 sound level meters and personal noise dosimeters. It should not be used for calibrating class 1 devices, but it still packs a punch with the same ergonomic design, quality and visual display for ease of use.
