| Title | Measurement microphones - Part 3: Primary method for free-field calibration of laboratory standard microphones by the reciprocity technique |
| Project Number | 6773 |
| Abstract/Scope | Applies to laboratory standard microphones meeting the requirements of IEC 61094-1. The principles of the method are applicable to other types of microphones. In particular, microphones which fulfil the requirements of IEC 61094-1, when fitted with a special adaptor, may also be calibrated according to this standard when the adaptor is removed. Specifies a primary method of determining the free-field sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure under free-field conditions.[ ]This publication supersedes IEC 60486. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
