Introducing the new Dual-Level Acoustic Calibrators from Cirrus Research

Cirrus Research is pleased to announce the addition of two all-new dual-level acoustic calibrators to our range of market-leading instrumentation.

The CR:516 and CR:517 dual-level acoustic calibrators can calibrate sound level meters and noise dosimeters in the field, using either the 94dB at 1kHz or 114dB at 1kHz levels that are featured as standard. These new dual-level acoustic calibrators are available as either Class 1 (CR:517) or Class 2 (CR:516) instruments and meet the strict demands of the IEC 60942: 2017 standard.

Here are some of the key features of our new dual-level acoustic calibrators:

  • IEC 60942: 2017 Class 2 & Class 1 performance
  • 94dB and 114dB sound pressure level output
  • Can be used for the calibration of sound level meters, noise dosimeters and instruments that require two levels of calibration
  • Suitable for use with standard 1/2″ microphone capsules
  • 1/4″ microphone adaptor available
  • Automatic power switch-off with user override, providing longer battery life
  • Robust case with ergonomic design


The CR:516 and CR:517 are now available to order from Cirrus Research as standalone units or can form part of a full noise measurement kit.
