Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.

There’s no such thing as a 1000-decibel sound. As Gyles pointed out, there’s no amount of energy in the world that can accomplish something like that. If you could somehow generate that much energy, it would generate a shockwave that would obliterate everything in its path.
What level of noise is acceptable UK?
Permitted noise levels The permitted noise level using A-weighted decibels (the unit environmental noise is usually measured in) is: 34 dBA (decibels adjusted) if the underlying level of noise is no more than 24 dBA.

Using dBA units, sound monitors can accurately reflect what noise frequencies the human ear will be sensitive to. Most dishwashers range from about 46 to 60 decibels. On the surface, this decibel level may not sound like much, but in reality, this is loud enough to interrupt a normal conversation.

At idle, it measured an average of around 42dB. I recorded an average of around 45dB with the sound on my speakers turned off while I was gaming. As you can see, there are plenty of cooling fans, and yet, the system is remarkably quiet.
Is 40dB loud for a PC?

In normal use my systems are 30-32dB and normal heavy work load is 35-37dB at 1 meter. 30dB(A) is a quiet room with no outside noise like traffic or a storm outside.
