DESCRIPTION

BS EN 61094-3:2016


This standard BS EN 61094-3:2016 Electroacoustics. Measurement microphones is classified in these ICS categories:
  • 17.140.50 Electroacoustics
  • 33.160.50 Accessories

This part of IEC 61094

  • specifies a primary method of determining the complex free-field sensitivity of laboratory standard microphones so as to establish a reproducible and accurate basis for the measurement of sound pressure under free-field conditions,

  • is applicable to laboratory standard microphones meeting the requirements of IEC 61094‑1 ,

  • is intended for use by laboratories with highly experienced staff and specialized equipment.

NOTE

The calibration principle described in this part of IEC 61094 is also applicable to working standard microphones, preferably used without their protection grid.
