Professional noise control not only helps companies achieve environmental compliance but also improves production environment quality and employee satisfaction. We recommend that companies conduct on-site inspections during the selection process and request simulated control solutions. We then use a six-dimensional evaluation system ("Qualifications - Technology - Case Studies - Service -...

By strictly controlling the thermal performance of building envelopes, improving equipment energy efficiency, and mandating the use of renewable energy sources (such as solar energy and air-source heat pumps), the new standard will significantly reduce energy consumption and carbon emissions during building operations, providing technical support for cities' low-carbon transition. Buildings...

Benefit: The government will pay to install soundproof windows for you, providing both ventilation and soundproofing, instantly improving your quality of life. Ventilated soundproof windows: A noise-reducing tool backed by policy. Highly effective: Reduce noise by 25-40 decibels. Simply close the windows and you'll be in a completely different world! National policies have paved the way for...

A new study from Oregon Health & Science University (OHSU) published in the Journal of the Association for Research in Otolaryngology reveals for the first time that children's central auditory systems are still developing before puberty, and their ability to combine binaural pitches may be a key factor in improving...
A new realm of sound insulation: revealing the four core elements of high-quality soundproof windows
September-30th-2025
3. "Three or more sealing strips, choose EPDM": Sealing strips are key to preventing sound leakage through gaps. Good soundproof windows will have three or more sealing strips between the window frame and glass, the window frame and wall, and the window sash and frame. These strips should preferably be made of EPDM, not ordinary rubber.
Analysis of aircraft-grade equipment noise and noise reduction measures
September-30th-2025
Optimize drive strategies: Implement variable frequency control on motors to avoid resonant speeds; optimize hydraulic system pressure and flow control strategies to reduce unnecessary impact and pulsation. Aircraft hydraulic system noise control focuses on source suppression (low-pulsation pumps, vibration dampers, valve optimization) and transmission path blocking (pump vibration isolation,...
Cooling tower noise causes and comprehensive treatment technology solutions
September-30th-2025
Cooling tower noise primarily comes from fan noise, including aerodynamic noise (proportional to the sixth power of the rotational speed) and mechanical vibration noise. Water flow noise is secondary, with water droplets impacting the sump, generating high-frequency noise of 70-80dB(A). The intensity is related to the height of the water drop and the flow rate. In Class 1 areas, exceeding the...

This conference focused on cutting-edge topics such as intelligent noise monitoring and noise reduction using metamaterials. It featured a main venue and sub-venues, with over 50 presentations analyzing technological breakthroughs and policy trends. Special guests included Wang Jie, an engineer at the Nuclear and Radiation Safety Center of the Ministry of Ecology and Environment; Wang Yun, a...

The noise generated by auxiliary equipment within satellite stations, such as exhaust fans, heat pumps, and circulating pumps, often exceeds the aforementioned standards. Low-frequency vibrations, in particular, propagate through building structures, causing persistent distress to surrounding residents and businesses. 1. Structure-borne sound transmission: Vibrations are transmitted along...

As core noise control technologies, soundproof enclosures and mufflers significantly reduce the impact of platform operations on the marine environment by reducing noise at the source and blocking its transmission. my country's Marine Environmental Protection Law and the Action Plan for the Prevention and Control of Pollution from Marine Oil and Gas Development explicitly require companies to...
