IEC 61094-8:2012 测量传声器.第8部分:利用比较法测定工作标准麦克风自由声场灵敏度

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. NOTE 1 This part of IEC 61094 is also applicable to laboratory standard microphones meeting the requirements of IEC 61094-1@ noting that these microphones also meet the electroacoustic specifications for working standard microphones. NOTE 2 This part of IEC 61094 is also applicable to combinations of microphone and preamplifier where the determined sensitivity is referred to the unloaded output voltage of the preamplifier. NOTE 3 Other devices@ for example@ sound level meters can be calibrated using the principles of this part of IEC 61094@ but are not within the scope of this standard.
