Sound barriers are an effective engineering measure for controlling noise propagation, mainly used in the following aspects. Their noise reduction effect and structural form (fully enclosed/semi-enclosed) differ significantly: Fully enclosed sound barriers (see below) theoretically have the best noise reduction effect, typically reducing noise by 20-30 dB(A) or more, effectively blocking...

Pumps and Fans: Cooling water pumps, circulating pumps, and fans in power plants generate significant noise during operation. Sound Barriers and Enclosures: Installing sound barriers or enclosures on noise-generating equipment (such as fans, pumps, and boilers) effectively isolates noise transmission and reduces environmental noise levels. Through...

Noise Control Measures for Metal Processing Plants: 1. Equipment Upgrades and Optimization: Use low-noise cutting machines, punch presses, and grinding machines to reduce noise generation at the source. 2. Management Optimization: Schedule high-noise processes during daytime non-rest periods to minimize impact on surrounding residents. 3. Phased Remediation: Prioritize remediation measures...
What are the noise control measures for booster stations in the oil and petrochemical industry?
2025-11-04
Vibration isolation: To reduce the impact of mechanical vibration on the environment and equipment, measures such as elastic supports and vibration damping pads can be used to isolate the noise source from the ground or building. By comprehensively applying noise source control, sound insulation and absorption, layout optimization, dynamic monitoring, and personnel protection, noise levels can...
Application of Ventilated and Soundproof Windows in Healthy Buildings
2025-11-04
II. Some Application Cases Case 1: Installation of Ventilation and Soundproof Windows in a Lanzhou Project Noise Category: Rail Transit Noise Previously, the road management had installed 4m high sound barriers, but this had little effect on residents on higher floors, and many residents still complained. Later, ventilation and soundproof windows were installed at noise-sensitive points, which...
What are some sound insulation and noise reduction measures for transformer rooms?
2025-11-04
4. Equipment maintenance and selection: Choosing transformer types and models with lower noise levels is also an important measure to reduce noise. Conclusion: Sound insulation and noise reduction measures for transformer rooms involve many aspects, from material selection and equipment layout to the installation of sound barriers. Only by comprehensively considering all aspects can the impact...
Ventilated and soundproof windows help create a "good house" and achieve a healthy new home!

By installing soundproof enclosures, the noise level in the work area can be ensured to meet the requirements of the "Hygienic Standards for Industrial Enterprise Design," which stipulates that the noise exposure time for employees should not exceed 85 dB(A) within an 8-hour period. Through the adoption of reasonable and effective sound insulation and noise reduction solutions, the selection...
What are the classifications and measures for industrial noise control?
2025-11-04
Regular maintenance: Regularly inspect and maintain the equipment to ensure proper operation, and promptly address worn and loose parts to reduce noise. Vibration damping design: During construction and production, incorporate vibration damping designs for equipment or processes that may generate impact noise, such as using rubber pads and foam materials. Safety measures during production...
