Typical vibratory feeder bowl constructed from 0.080” to 0.15” stainless steel.  This unit generated 101 dBA noise levels prior to treatment with HBDC-200.

Operation of the feeder bowl dropped from 101 dBA to 89 dBA after treatment.   HUSH BRUSH™ model HBDC-200 material was applied to the outside of the bowl and to underside surfaces of the trays and ramps.
