Acoustic Calibrators
In order to provide an accurate response from a sound meter or any noise measuring instrument, it is crucial to check the meter before and after use. Many regulations and international standards make it mandatory to carry out these checks, so owning a field calibrator becomes a specific requirement of any noise measuring kit.
This category has a range of Acoustic Calibrators for field calibrations, that provide a quick and simple way to check that a meter is measuring and functioning as it should. Castle can provide several different calibrators for different instruments including both single-level and dual-level noise meter calibrators.
Benefits of carrying out field calibrations with an Acoustic Calibrator
Apart form the mandatory requirement to conduct regular calibration checks of a sound level meter, these sound calibrators will also provide peace of mind that the measurements you are taking have a verifiable source or pre- and post-measurement checks.
How often does a sound meter need to be calibrated?
To remain compliant, most sound meters must be calibrated in a laboratory or calibration house every 24 months and calibrators themselves should be returned every 12 months
The United Kingdom Accreditation Service (UKAS) has issued a guide (LAB23) on calibration of Sound Meters and Calibrators in which it states recommended calibration intervals for various types of equipment, some of which are listed here:
Personal Dosemeters - 1 year
Microphones (Reference and Working) - 2 years
Sound Meters (tested to BS7580, where applicable) - 2 years
Sound Meters built to IEC 61672:Part 1 - 2 years
Sound Analyser for Building Acoustics Work - 2 years
All other Sound Meters - 1 year
Acoustic Calibrators (Mechanical or Electronic) - 1 year
