According to the national standard, the noise limit of general laboratories is below 60 decibels, but for some laboratories that need high quiet, such as acoustics laboratories and precision instrument laboratories, the noise limit may be lower, usually below 40 decibels.

In order to reduce laboratory noise, low-noise equipment and instruments can be selected. Sound insulation and vibration reduction of equipment and instruments. Acoustics design laboratory, using sound absorption materials and sound insulation structure.
