metal rod mill noise control

CDC - Mining - Noise Reduction of a Pneumatic Rock Drill ...

Drill steel resonance noise is reduced by a constrained-layer treatment consisting of a tubular metal cover bonded to the outside of the rod by a viscoelastic filler. Damping alloy components have been developed to reduce metallic resonance noise. Combined, these modifications have reduced the drilling noise level in granite from 115 dba to 97 dba.

Perforated Metal Acoustic Panels Sound Absorbing Panels

Perforated metal is the primary component in the manufacturing of noise control systems and noise control products. When perforated metal is used as a decorative cover or as protection for an acoustical material, the sound waves travel right through the “transparent” metal to the material underneath that reflects, scatters or absorbs sound in a certain way.
