Silencing equipment with loudness monitoring and grading treatment functions

Abstract

The invention discloses silencing equipment with loudness monitoring and grading treatment functions. The silencing equipment with loudness monitoring and grading treatment functions comprises a first half shell and a second half shell, fixing rods are fixedly connected to the inner wall of the first half shell and the inner wall of the second half shell correspondingly, and a silencing barrel is fixedly connected between the two fixing rods. The inner wall of the silencing barrel is fixedly connected with a first sound absorption partition plate, a second sound absorption partition plate, a silencing hole plate and a sponge sound absorption plate from top to bottom. According to the silencing equipment, the first sound absorption partition plate and the second sound absorption partition plate are arranged, and the three partition plates are arranged in a crossed mode, so that a sound circulation path is longer, and a better silencing effect is achieved. Secondary silencing treatment is conducted when sound passes by arranging the silencing hole plate, the sponge sound absorption plate and sound absorption cotton balls, so that the silencing effect of the equipment is further improved. A sound detector and a display screen are arranged, so that the sound can be correspondingly monitored, and the noise pollution degree in the surrounding environment can be known.

Description

technical field [0001] The invention relates to the related technical field of noise reduction equipment, in particular to noise reduction equipment with loudness monitoring and hierarchical processing. Background technique [0002] Noise elimination refers to taking appropriate measures to reduce or eliminate the noise of the air-conditioning and ventilation system. Noise control has two aspects. One is the noise control of the service object of the HVAC system; the other is the noise control of the equipment room of the HVAC system. While the ventilation and air conditioning system controls the heat and humidity environment and air quality in the building, it also affects the acoustic environment of the building to varying degrees. When sending and returning air outlets and other components, due to the turbulent vibration of the components by the impact of the air flow or the deflection and vortex of the air flow, air flow regeneration noise will be generated, so correspon...
