3 terminology and units of measurement

JJF 1001, terms and definitions and JJG188 JJF 1034 defined in applicable to this specification. This specification uses quantities and units GB 3102.5 and GB 3102.7 prescribed.

4 Overview

Conditioning is a kind of filtering, frequency weighting, signal amplification, the microphone power supply and other functions of the instrument, Widely used in electro-acoustic measurement and analysis, such as calibration microphone, audiometer calibration, noise measurements.

5 Metrological characteristics

5.1 linear frequency response Conditioning linear output frequency range is generally 20Hz ~ 20kHz; 1kHz reference to its frequency Response generally no more than ± 0.5dB. 5.2 Linear Conditioning attenuation or gain typically 10dB steps. With respect to "1V/Pa" or "0dB" stop all Various other gear introduced at 1kHz error of not more than ± 0.4dB. 5.3 Frequency weighting Conditioning of the A, C weighting and the maximum permissible error in Table 1. ......
