Noise Abatement Company Implements Sound Dampeners

For construction sites, the noise from machinery engines is actually not too loud. The key is that processes like equipment movement, material collisions, excavation, drilling, and demolition inherently cause widespread vibration, which cannot be silenced at the source. Below, the editor will briefly discuss this with everyone.Noise Abatement CompanyThe mufflers used include: 1. Resistance mufflers with excellent mid-frequency and high-frequency noise reduction performance, which are categorized by different airflow channel shapes: straight pipe, plate, corrugated plate, honeycomb, streamline, elbow, and small zero. Micro-perforated plates belong to this type, primarily used for air conditioning ventilation systems and noise reduction for mid-frequency and high-frequency noise.

2. Resonant silencers are categorized into resonant, constrictive, dilative, and microporous types. There are clear rules for the selection and design of resonant silencers in noise management, such as when dealing with mid-to-high-frequency characteristics, the pipe diameter should not exceed 400mm, and a plate-type silencer can be chosen. The plate spacing can be 100-200mm, and the plate thickness 50-150mm.3. The impedance composite silencer combines the resistive silencer, which is effective in reducing high and medium-frequency noise, with the reactive silencer, which is effective in reducing medium and low-frequency noise. This results in a more pronounced noise reduction effect. Its application is widespread, but it should not be used in areas with steam corrosion or high temperatures.
