Soundproof Cover
The soundproof cover protects operators from loud noise by effectively decreasing structure-borne and airborne noise. It also plays a critical role of minimising chemical splash. Typically, the effective ones are full sound-absorbing cabins and the design of both enclosing components of each soundproof cover does not interfere with the vibratory finishing machine’s functionality.
Made using special technology, the soundproof cover helps minimise the noise level by 57% compared to a machine operating with a soundproof cover. However, the level of noise relies on various factors, including the machine size, type and size of media and components utilised in the process. The drive system also generates the vibratory force that affects the noise level. The cover ensures that the machines operate quietly, eliminating the need for a special noise deadening enclosure.
The sound cover is made up of a 2mm rigid steel basement structure with a laser cutting structure consisting of plasma wielding. The cover contains a special wave-shaped material on the inside that acts as a sound absorber. Furthermore, there are several external and internal bubbles and pores.
Upon the incident of sound waves on the bubbles and pores, the air vibrates in the gap. A significant amount of sound energy is transformed into thermal energy and used up as a result of air resistance as it circulates. The friction between the hole walls and the air also generates friction, which produces thermal energy. Heat exchange also takes place between the hole wall and the air as the air is adiabatically compressed.
