The ordinary and maximum tolerance limit of sound by human being is
-
- 50 db to 70 db (decibel)
- 60 db to 80 db (decibel)
- 65 db to 75 db (decibel)
- 70 db to 85 db (decibel)
- 50 db to 70 db (decibel)
Correct Option: B
Normal speech is about 60 dB (decibels). A dangerous sound is anything that is 80 dB or higher which can lead to hearing loss. At 70 dB or lower, the risk of harm to healthy ears is negligible. Listening to sound above 80 decibels can cause profound deafness.
