What is BS EN 61183 - Diffuse-field calibration of sound level meters about?
BS EN 61183 is an international standard that discusses turbine meters random-incidence and diffuse-field calibration of sound level meters.
BS EN 61183 describes a free-field calibration method for determining random-incidence sensitivity levels of sound level meters. Additionally, BS EN 61183 describes a diffuse-field calibration method for determining diffuse-field sensitivity levels.
BS EN 61183 discusses diffuse-field sensitivity level which is used interchangeably with random-incidence sensitivity level. The selection of calibration method depends on the facility available. Results of calibrations conducted in accordance with BS EN 61183 depend upon which components of a sound level meter are exposed to the sound field.
As per BS EN 61183, a sound level meter is a conventional sound level meter, an integrating-averaging sound level meter, or any other sound measuring system.
Who is BS EN 61183 - Diffuse-field calibration of sound level meters for?
BS EN 61183 on diffuse-field calibration of sound level meters is relevant to:
- Manufacturers and designers of sound level meters
- Acousticians
- Electrical engineers
- Electricians
- Testing authorities
Why should you use BS EN 61183 - Diffuse-field calibration of sound level meters?
A sound level meter is a conventional sound level meter, an integrating-averaging sound level meter, or any other sound measuring system. A random incidence sound field relates to a given location and for a given frequency or frequency band centred on that frequency, a sound field.
BS EN 61183 discusses definitions that depict a user-friendly idea of sound level meters. BS EN 61183 also provides users with different calibration methods which contribute to the performance characteristics of sound level meters ensuring their reliability.
Overall, BS EN 61183 is useful as it provides guidance on the random-incidence and diffuse-field calibration of sound level meters that can be beneficial for your business and can help you to expand your business globally.
