How long can I listen to 80db?
You can listen to sounds at 70 dBA or lower for as long as you want. Sounds at 85 dBA can lead to hearing loss if you listen to them for more than 8 hours at a time. Sounds over 85 dBa can damage your hearing faster. The safe listening time is cut in half for every 3-dB rise in noise levels over 85 dBA.
How many decibels (dB) do you need for earplugs?

What does 40 decibels (dB) mean?
Relative means that dB is only a useful measurement when compared to other dB values. Logarithmic means that, for every 10 dB, the corresponding real-world volume doubles. 40 dB is twice as loud as 30 dB, and half as loud as 50 dB. Image credit: Kerry Raymond, Wikimedia Commons
