Design of Noise Measuring Instrument and Its Implementatio

  • In view of noise hazard of coal mine underground, the paper proposed a design scheme of noise measuring instrument based on STC single-chip microcomputer, and introduced hardware and software design of the instrument. The test results showed that the instrument realizes accurate measurement of noise level, measurement error is less than ±1.25%, which reaches 2-level of sound level meter.
