INTRODUCTION
Musktool-HY603, Musktool-HY604 and Musktool-HY605 sound calibrators comply with GB/T 15172—2010/IEC 60942:2003 "Electroacoustic Acoustic Calibrator" requirements, it applies to Calibration of noise measuring instruments such as Microphones and sound level meters with nominal diameters of 23.77 mm, 12.7 mm and 6.35 mm. They use a sturdy and concise structure and exterior Shape design, simple operation. Musktool-HY603 is a class 2 sound calibrator, and Musktool-HY604 is a class 1 sound calibrator. Both of them 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 of the instrument and the error of the level range controller, which helps to find the faults and defects of the instrument. Musktool-HY605 is a class 1 multi-frequency sound calibrator with three nominal frequencies of 250 Hz, 500 Hz and 1000 Hz. In addition to calibrating the sensitivity of the noise measuring instrument, it can also roughly check the frequency weighting of the instrument And the frequency response of the microphone, which helps to find malfunctions and defects of the instrument. The Musktool-HY604 and Musktool-HY605 sound calibrators use a single-chip computer as the core, use digital synthesis technology to generate accurate and stable sinusoidal signals, and use built-in reference microphone sound feedback technology and temperature automatic correction technology to make the sound pressure levels they produce Very good temperature stability and static pressure stability. |
