According to the national standard, the general laboratory noise limit is below 60 decibels, and for some laboratories that require a high degree of quietness, such as acoustic laboratories and laboratories for precision instruments, the noise limit may be even lower, usually below 40 decibels.
To reduce laboratory noise, low-noise equipment and instruments can be selected. Soundproof and dampen equipment and instruments. Acoustically design the laboratory with sound-absorbing materials and sound-insulating structures.
