How to control noise from dust collector fans in cement plants?
2025-11-04
For heavy industrial equipment like cement plants, noise control, especially for dust collector fans, is a critical issue. I. The Necessity of Noise Control Dust collector fans are key equipment in cement plants for treating dust and exhaust gases within the plant area; however, the noise they generate during operation causes significant disturbance to the plant area and surrounding residents...
Types and functions of industrial silencers

Its function is to convert noise energy into other forms of energy through mechanisms such as sound absorption, reflection, and scattering, thereby reducing noise to an acceptable level. A soundproof enclosure is a sealed shell filled with sound-absorbing material, and its reasonable structural design and sealing performance reduce noise leakage. Besides sound absorption, reflection, and...
How much do you know about noise reduction for building equipment?
2025-11-04
Noise Impact Assessment: This involves analyzing the specific impact of equipment noise on the working and living environment inside the building to determine the degree of noise reduction required. In general, noise reduction for HVAC equipment is a systematic project that requires a multi-pronged approach, including noise source analysis, vibration reduction measures, pipe noise reduction,...

Sanyuan Environmental Ventilation and Soundproof Windows, with their synergistic "sound insulation + ventilation" technology, break the paradox of traditional doors and windows where "silence leads to oxygen deficiency, while ventilation leads to noise," redefining the standard for a healthy living acoustic environment. • Military-grade sealing system: EPDM composite foam strips + elastic...
What are some measures to control noise from steam turbines?
2025-11-04
2. Vibration Reduction and Balancing: Measures such as vibration damping pads and elastic supports are used to reduce the vibration and structural noise of the steam turbine. Through proper design and adjustment, vibration damping devices can reduce resonance between the blades and impeller, thereby reducing noise. Sound-absorbing panels and sound-absorbing cotton can be installed around the...

Impact noises (such as footsteps or falling objects): These are caused by vibrations from objects hitting floors or walls, transmitted through the building structure, and are a current challenge for residential sound insulation. Direct transmission: Vibrations travel through floors → walls → ceiling → indoor air, creating audible noise. Door and window gaps: Poorly sealed sliding windows and...

The most fundamental difference between home soundproofing and hotel soundproofing lies in the management unit. Homes are managed on a household basis, with property management acting as an assistant; home interior design cannot be uniformly planned. Hotels, on the other hand, are managed as a company, allowing the hotel manager to plan the entire building's interior design and soundproofing....

By designing special ventilation channels, sound waves undergo multiple reflections and attenuation before entering the room, thus reducing noise. Energy-saving and environmentally friendly: Through the design of multi-layered glass and sealing strips, the ventilated and soundproof window has excellent thermal insulation performance, reducing heat loss in winter and heat gain in summer, thus...
A Complete Guide to Noise Control: From Wall Soundproofing to Comprehensive Solutions

New regulations for residential buildings in Hangzhou increased the thickness of partition walls from 200mm to 240mm, but this only improved sound insulation by 2 decibels, solving only 50% of the internal sound insulation problem. International acoustics forum tests showed that a 400mm thick brick wall (700kg/m²) provides 46dB of sound insulation, while a 100mm brick wall + 160...
What are some noise reduction measures for industrial pump rooms?
2025-11-04
4. Vibration and Noise: Improper installation and operation of equipment in the pump room may cause equipment vibration, which in turn causes structural vibration noise, such as resonance effects from the ground, walls, and pipes. Noise sources (such as pumps, generators, and equipment motors) should be enclosed, and ventilation devices should be installed to ensure heat dissipation...
What are the noise sources in a production workshop and how to deal with them?
2025-11-04
II. Noise Control Measures in the Production Workshop 1. Equipment Maintenance and Upgrading: Regularly inspecting and maintaining mechanical equipment, such as lubricating, repairing loose parts, and replacing worn components, can reduce noise generation. When designing and selecting equipment, consider reducing operating speed, impact, and vibration; rationally arrange production processes...
