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...
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...
Traffic noise nuisance from elevated roads, subways, and rail lines isn't unique to Shenzhen; it affects virtually every city. While common control measures can bring noise levels up to standard, the impact of noise on people is highly subjective. Meeting standards doesn't necessarily mean it's not disturbing.

Short-term exposure to loud noise (e.g., a 2-hour electric drill) can cause temporary swelling of the cochlear hair cells, which can then recover. However, prolonged exposure can cause the hair cells to break and die, causing irreversible damage to the ear and hearing loss. A study published in The Lancet Neuroscience found that exposure of healthy subjects to 1...
Impact noise (such as footsteps or objects falling): Vibrations generated by objects striking the floor or wall are transmitted through the building structure, making it a current challenge for residential soundproofing. Direct transmission: Vibrations travel through the floor, walls, ceiling, and indoor air, creating audible noise. Gaps in doors and windows: Poor sealing of sliding windows...
