DIN EN 61094-2
Electroacoustics - Measurement microphones - Part 2: Primary method for pressure calibration of laboratory standard microphones by the reciprocity technique (IEC 61094-2:2009 + AMD1:2022); German version EN 61094-2:2009 + A1:2022
Elektroakustik - Messmikrofone - Teil 2: Primärverfahren zur Druckkammer-Kalibrierung von Laboratoriums-Normalmikrofonen nach der Reziprozitätsmethode (IEC 61094-2:2009 + AMD1:2022); Deutsche Fassung EN 61094-2:2009 + A1:2022
Overview
This is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphone having the same mechanical dimensions and specifies a primary method of determining the complex pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure. The standard differs from DIN EN 61094-2:2009-09 as follows: a) Clause 5 has been revised; b) a new subclause 6.6 has been added; c) Note 2 in 7.3.3.1 has been deleted; d) subclause 7.3.3.1 has been revised; e) Annex A has been revised; f) Annex E has been revised. The International Standards IEC 61094-2:2009 and EN 61094-2/A1:2022, on which this standard is based, have been prepared in IEC/TC 29 "Electroacoustics" with German collaboration. Joint Committee NA 001-01-03 GA (NALS/DKE A 3) "Schallmessgeräte" ("Sound measuring instruments") under the chairmanship of NALS is responsible for the German participation.
