Remember: a 5mm gap can ruin a wall's soundproofing! Flooring: Large carpeting, especially with thick, soundproofing mats, can significantly absorb mid- and high-frequency noise and vibrations, such as footsteps and dragging objects. These natural sound absorbers reduce reflections and reverberation in the room, making the space feel more...

Automatic noise monitoring systems, through real-time monitoring and data management, provide an effective solution for the development of smart, environmentally friendly cities. Using voiceprint recognition and sound source location technology, these systems accurately trace the location and frequency of noise, providing a basis for management. With the continuous development of the Internet...
[Weekly Science] Technical Architecture of Reverberation Time Control
September-30th-2025
Reverberation time is the time it takes for the diffuse sound pressure level in a room to decay by 60dB after the sound source ceases. Sound absorption and noise reduction are tools for controlling reverberation time. The difference in sound pressure level before and after treatment is: △Lp = 10lg (T after / T before). The ratio of reverberation time before and after sound absorption treatment...

Beware of the "hearing killers" around you - take stock of the noises you ignore
September-30th-2025
Protection recommendations: Follow the "60/60 rule"-keep the volume no higher than 60% of the maximum volume, and use it for no more than 60 minutes at a time. Prioritize noise-canceling headphones, which can reduce the volume by 20-30 decibels in noisy environments. Daily habits to protect your hearing: 1. Regular hearing checks: Have one at least once a year...
