[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - decontamination] noise control noise standards are generally stricter than cleanroom standards to protect the health refrigeration room project aims to protect the normal operation of the ventilation duct works, to meet the need Contact conversation and a safe and comfortable working environment. Therefore, the main indicator to measure the noise of the clean room is: 1. Effects due to noise annoyance, people feel uneasy mood generated worry, generally divided into very quiet, very quiet, quieter, somewhat noisy, relatively noisy and very noisy annoyance grade seven. Where the level of response are very noisy and very loud person, namely high percentage troubles, troubles high number is the total number of high annoyance rate. 2. Impact on the efficiency of which mainly depends on the level of response in three areas, these three areas are: concentrate, movement accuracy, speed work; 3. Integrated communications interference which is mainly divided into: clear or satisfactory, slightly difficult, difficult, impossible are used to evaluate the A sound level indicator on the above three aspects. In the 1950s, had proposed using a spectral curve as the evaluation criteria that each band center frequency sound pressure level shall not exceed the curve. A brush later learned to measure the noise level of the speech and noise disturbance and annoyance more Taiwan proper extent, can replace octave band sound pressure levels as indicators of evaluation criteria.
