A noise reduction room for power equipment

Abstract

The invention discloses a noise reduction chamber for power equipment. The noise reduction chamber comprises a base. A first baffle and a second baffle symmetrical to the first baffle are fixedly connected to the top of the base. The interior of the first baffle and the interior of the second baffle are each provided with a cavity. A cover plate is arranged at the tops of the first baffle and the second baffle. An air outlet is formed in the top of the cover plate. An air inlet is formed in one side face of the second baffle. A first gypsum board is fixedly connected with the inner bottom wall of the base. Deadening felt is arranged at the top of the first gypsum board. One side face of the first baffle and one side face of the second baffle are provided with sound absorbing holes distributed at equal intervals. A sound guiding pipe is arranged at one end of each sound absorbing hole, and the sound guiding pipe communicates with the sound absorbing hole. According to the noise reduction chamber for the power equipment, energy of sounds is consumed through circulation and transferring of interiors of sound absorption balls to the sounds, the noise is lower and lower, the noise penetrability is reduced, the purpose of noise reduction is achieved integrally, the situation that a worker loses hearing for working in the noisy working environment for a long time is avoided, and the physical and psychological health of the worker is guaranteed.

Description

technical field [0001] The invention relates to the field of noise technology, in particular to a noise reduction room for power equipment. Background technique [0002] Noise refers to the chaotic and disharmonious sound of pitch and intensity changes. In industrial construction, high-power power equipment is often used, and the overall noise is too strong. Workers work in a noisy environment for a long time, which gradually deteriorates the hearing of the workers and seriously affects the physical and mental health of the workers. Contents of the invention [0003] The purpose of the present invention is to provide a noise reduction room for power equipment to solve the problems raised in the background art above. [0004] To achieve the above object, the present invention provides the following technical solutions: a noise reduction chamber for power equipment, including a base, the top of which is fixedly connected with a symmetrical first baffle and a second baffle, ...
