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.
