8. Sound Enclosure Instructions
The Sound Enclosure provides personal protection from the noise generated by ultrasonics. The
enclosure reduces sound levels by approximately 25% when compared to sonication done in an open
setting. For example, the standard ½” horn produces 90 dB and when used inside the Sound
Enclosure, the noise is reduced to 73 dB.
