Question

Immediate damage is caused to human ears if exposed to the sound of loudness over ____ .

• A. 120 dB
• B. 75 dB
• C. 80 dB
• D. 60 dB

Answer 1

The correct option is A 120 dB

Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
