Sound travels faster underwater, but this does not mean that divers hear better underwater. It just means that the sound is heard more quickly.
they can hear better out of the water
"better" isn't really the right word. Noise travels faster through water than in air, OTOH you need a sound source capable of generating sound while submerged.
People hear better under water because there aren't as many sound particles in the water so u can hear everything better
Yes
Hearing under water is easy, although speaking under water is difficult. Water conducts sound quite well, better than air does, in fact.
Yes, you can hear under water.
This is the same as asking if you can hear under water and yes, you can hear under water.
Yes.
the hear really well under water and on land
sonar
yes they can. It is muffled, like when someone talks when we are under water, but they can hear it! no,when we are under water and alive with senses in our brain to detect and compare, is assumed we hear,but for a baby that is not yet born, can't hear anything
cause its easier for sound waves to travel through air than through liquid
