1, medical purification project within the noise spectrum limitations should be used octave sound level; the frequency band sound pressure level value should not be greater than 1 of the provisions;
2, medical purification project of the flat, sectional arrangement, should take into account the requirements of the noise control, and its enclosure should have a good performance of the sound isolation, and it is desirable to make the sound isolation of various parts of the amount of proximity;
3, various equipment should be selected low-noise products. /p>
3, medical purification project within the various equipment should be selected low-noise products. For radiation noise exceeding the permissible value of the clean room equipment, should be set up special sound insulation facilities (such as acoustic isolation, acoustic enclosure, etc.);
4, medical purification engineering purification air conditioning system noise exceeds the permissible value, should be taken to isolate the acoustic insulation, muffling, acoustic vibration and other control measures. In addition to accidental exhaust, should be clean room exhaust system for noise reduction design.
