Urban sound insulation strategy

Nowadays, the city is very noisy, and there are many people who have nightlife, especially those who live in the city center. If you want good indoor sound insulation, you can use the following methods.

Environmental protection sound-absorbing cotton

Environmental sound-absorbing cotton is a kind of environmental sound-absorbing cotton with low density and high porosity, which has excellent smoldering property, sound absorption and heat insulation. Widely used in construction, industry, transportation, aerospace, electromechanical, household appliances, electronic products and other fields with requirements for improving sound quality, controlling noise and heat insulation. The fire resistance of sound-absorbing cotton reaches A 1.

Ceiling damper

The ceiling shock absorber is a necessary part of ceiling sound insulation. Its unique damping rubber block and spring can cut off the transmission of sound source, especially suitable for all subwoofers in entertainment venues. It can also be used as a pipe hanger between equipment such as water pump room to eliminate low-frequency sound transmission, and the effect is very obvious.

skylight

There are many kinds of blinds. On the one hand, louvers used in noise control should be ventilated to dissipate heat, on the other hand, they should be silenced and sound-insulated, so as to reduce or isolate noise from spreading outward. Acoustic louvers are mostly used in fresh air inlet of ventilation system, return air outlet of corridor, ventilation and noise elimination of cooling tower, air conditioning of sound barrier vent, vent of cooling device and many other occasions. What material has good sound insulation effect?

Ground sound insulation pad

It has a particularly good sound insulation effect on impact sound in the whole frequency range, and can effectively isolate impact noise and air-borne noise. This kind of foam is a kind of high-density foam, and its perforation rate and aperture are specially designed, which can achieve the effects of sound insulation, shock absorption, waterproof and mildew prevention, and is suitable for various humid environments. It is environmentally friendly and has a service life of over 30 years. The construction is simple, and the cutter is used for cutting during installation without other tools.
