What is this BS EN 61094-1 - Measurement microphones about?
BS EN 61094-1 discusses measurement microphones with a focus on specifications for laboratory standard microphones.
BS EN 61094-1 is the first part of the BS EN 61094 multi-series on measurement microphones that specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure and for sound pressure measurements of the highest attainable accuracy. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out.
Who is BS EN 61094-1 - Measurement microphones for?
BS EN 61094-1 on measurement microphones is useful for:
- Manufacturers of measurement microphones
- Testing authorities
- Recording studios
- Sound-field personnel
Why should you use BS EN 61094-1 - Measurement microphones?
The sound pressure in a given sound field will generally depend on position and should ideally be measured at a point with a transducer of infinitesimal dimensions and infinitely high acoustic impedance. However, the finite dimensions and the acoustic impedance of a real microphone, and the mounting of this microphone, cause practical measurements of sound pressure to depart from this ideal.
BS EN 61094-1 establishes a system for classifying laboratory standard condenser microphones
into a number of types according to their dimensions and properties in order to facilitate the specification of calibration methods, the conducting of inter-laboratory comparisons involving the calibration of the same microphones in different laboratories, and the interchangeability of microphones in a given calibration system.
BS EN 61094-1 helps carry out primary calibration by the reciprocity method.
