    HY604 type sound calibrator
     
    Introduction:
    The HY604 type sound calibrator meets the requirements of the national standard GB/T15173-2010 and the international standard IEC 60942:2003 "Electroacoustic Sound Calibrator" for Class 1 sound calibrator. It is suitable for microphones with a nominal diameter of 23.77 mm and 12.7. Calibration of noise measuring instruments such as microphones and sound level meters of mm and 6.35 mm. HY604 can produce two nominal sound pressure levels of 94 dB and 114 dB. In addition to calibrating the sensitivity of the noise measuring instrument, it can also roughly check the level linearity and level range controller errors of the instrument. Find out the malfunctions and defects of the instrument.
            The HY604 sound calibrator is based on a single-chip microcomputer. It uses digital synthesis technology to generate accurate and stable sinusoidal signals. It uses built-in reference microphone acoustic feedback technology and temperature automatic correction technology to make the sound pressure levels they produce have good temperature stability. Performance and static pressure stability.
    Technical Parameters:
    Performance level: GB/T15173/IEC 60942 level 1.
    Nominal sound pressure level: 94 dB and 114 dB (reference is 2×10-5 Pa), the main sound pressure level is 94 dB (corresponding to a sound pressure of 1 Pa).
    Nominal frequency: 1 kHz.
    Tolerance of sound pressure level: ±0.25 dB.
