85 decibels is the maximum recommended exposure limit for human hearing. It is a loud noise level comparable to that of heavy traffic or a snowblower. 85 decibels is considered to be the maximum level of noise we should expose ourselves to for longer than 8 hours at a time.

Food blender (88 dB); milling machine (85 dB); garbage disposal (80 dB). 80: 2 times as loud as 70 dB. Possible damage in 8 h exposure. Passenger car at 65 mph at 25 ft (77 dB); freeway at 50 ft from pavement edge 10 a.m. (76 dB). Living room music (76 dB); radio or TV-audio, vacuum cleaner (70 dB).

2024年2月28日 · We know now 85 dB is a relatively high noise level. It can become dangerous to your ears and, in the worst cases, can even cause hearing loss. But the question is: How can you identify an 85 dB noise? And how can you determine when to stop listening to a noise? Here is what 85 dB sounds like when compared to other noise levels: 50 Decibels

2024年2月16日 · The NIOSH recommended exposure limit (REL) for occupational noise exposure is 85 A-weighted decibels (dBA) over an eight-hour shift. If workers are repeatedly exposed to noise at or above the REL, employers must provide a hearing loss prevention program.

2022年9月26日 · 一般规定24~55方的噪声测量选择A计权；55~85方的噪声测量选用B计权；对85方以上的噪声测量选用C计权。 在进行音频功率放大器的噪声测试的时候，一般采用的都是A计权后的数值。 可以从手册中看出，在进行输出噪声的电气参数描述的时候，一般会在备注栏写上A-weighted。 需要注意的是，虽然A计权测量结果并不是非常令人满意，但是它作为一个传统的计量手段，一直得到广泛的应用。 下图是A、B、C、D四种计权的频率响应曲线。 如果想要知道 …

2024年11月6日 · Sound levels are most commonly measured in decibels (dB), which range from barely audible to loud enough to cause physical pain. The risk of hearing loss starts at around 70 dB. Exposure to sounds at 85-decibel levels and above damages your hearing.

2025年2月27日 · 85 decibels (dB) is a measurement that quantifies sound intensity. In practical terms, it’s equivalent to the noise level of heavy traffic, a loud vacuum cleaner, or an alarm clock from close range.

1 天前 · Understanding What dB is Too Loud. According to various health organizations, sounds that exceed 85 dB can pose a risk to hearing health, especially with prolonged exposure. Continuous exposure to sounds at this level can cause noise-induced hearing loss (NIHL), a condition that can be both irreversible and debilitating. The Risks of Loud Sounds

85分贝：长期作用下会引起听力损伤. 90分贝：10英尺（约3米）外经过的公共汽车或卡车；食物搅拌机. 100分贝：一般家用音响设备的最大音量. 104-107分贝：开始引起疼痛的声音（在2750Hz的频率下） 110-140分贝：100米外的 喷气式飞机引擎

2024年2月15日 · Dangerous Range (85 to 115 dB) Sounds at this range can damage your hearing—either immediately or through prolonged exposure. Without ear protection, nobody should be exposed to 90 dB for more than 8 hours per day, 100 dB for 2 hours, 105 dB for 1 hour, or 110 dB for more than half an hour.
