You can start to hear at the threshold of hearing at 0 dB and end up at the threshold of pain at 137.5 dB.
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
When your ears get more then the loudness of 85 dB for a longer time it is dangerous.
The decibel (abbreviated dB) is the unit used to measure how loud a sound is. The decibel scale is a little odd because the human ear is incredibly sensitive. Your ears can hear everything from your fingertip brushing lightly over your skin to a loud jet engine. In terms of power, the sound of the jet engine is about 1,000,000,000,000 times more powerful than the smallest sound that your ears can just barely hear. That's a big difference!On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB140 dB airplane taking off150 dB firecracker157 dB balloon pop162 dB fireworks (at 3 feet)
Around 150 decibels would make you become deaf, and, unbelievably, around 190 decibels could kill you. It depends also on the listening time. More than 85 dB SPL a long time is not good for your ears. One bang of 140 dB SPL will hurt you very much.

You can't hear much only faint noises s your ears only develop in the second trimester.
So they can hear, just like humans have ears so they can hear.
Sea lions are in the family Otariidae ("eared seals"), therefore they have external ears and hear stuff very much the same way we do. The family Phocidae ("earless seals") has no visible ears, but can still hear.
Levels higher than 130 dB are close to the treshold of pain. That's not good for your ears.
you can hear by sound wave and ears
humans hear from there ears.
they hear by their ears duhhh
