How mush noise is safe ?
Knowing what constitutes “safe” noise levels is essential for hearing protection. A sound’s decibel level (dB) is only one factor to consider; another is the duration of exposure. Permanent hearing loss can result from repeated or prolonged exposure to loud noises.
Here are some examples of noise levels that can cause pain and injury
Shotgun - 150 dB
Firework - 140 dB
Jackhammer - 130 dB
Sirens - 120 dB
Loud noises at these levels can damage your hearing in 2 to 15 minutes.
Rock Concert - 110 dB
Car Horn - 100 dB
Such noise levels are capable of causing annoyance and stress.
Shouting Conversation - 95 to 85 dB
Vaccum Cleaner - 80 to 70 dB
These sound levels usually won't harm your hearing
Normal Conversation - 60 to 40 dB
