Measurement microphones - Part 8: Methods for determining the free-field sensitivity of working standard microphones by comparison

This part of the IEC 61094 series is applicable to working standard microphones meeting the requirements of IEC 61094-4. It describes methods of determining the free-field sensitivity by comparison with a laboratory standard microphone or working standard microphone (where applicable) that has been calibrated according to either:
– IEC 61094-3,
– IEC 61094-2 or IEC 61094-5, and where factors given in IEC/TS 61094-7 have been applied,
– IEC 61094-6,
– this part of IEC 61094.
Methods performed in an acoustical environment that is a good approximation to an ideal free-field (e.g. a high quality free-field chamber), and methods that use post processing of results to minimise the effect of imperfections in the acoustical environment, to simulate freefield conditions, are both covered by this part of IEC 61094. Comparison methods based on the principles described in IEC 61094-3 are also possible but beyond the scope of this part of IEC 61094.

Merilni mikrofoni - 8. del: Metode za določanje primerjalne občutljivosti v odprtem prostoru delovnih mikrofonov

Ta del skupine standardov IEC 61094 se uporablja za delovne mikrofone, ki izpolnjujejo zahteve iz standarda IEC 61094-4. Opisuje metode za ugotavljanje občutljivosti v odprtem prostoru s primerjavo z laboratorijskim standardnim mikrofonom ali delovnim mikrofonom (kjer je to primerno), ki je bil umerjen v skladu s:
– standardom IEC 61094-3,
– standardom IEC 61094-2 ali IEC 61094-5, pri čemer so bili uporabljeni faktorji iz standarda IEC/TS 61094-7,
– standardom IEC 61094-6,
– tem delom standarda IEC 61094.
Ta del standarda IEC 61094 zajema metode, ki se izvajajo v akustičnem okolju, ki je dober približek idealnemu prostemu zvočnemu polju (npr. visokokakovostna gluha komora), in metode, pri katerih se rezultati naknadno prilagodijo, da se čim bolj zmanjša učinek nepravilnosti v akustičnem okolju, s čimer se simulirajo pogoji prostega zvočnega polja. Možne so tudi primerjalne metode, ki temeljijo na načelih iz standarda IEC 61094-3, vendar ne spadajo na področje uporabe tega dela standarda IEC 61094.
