Yes and no.
The detection of sound waves actually works better in water than in air because water transmits pressure waves more efficiently.
However, the difference in density means that human speech sounds are muffled or garbled underwater, making talking across a distance practically impossible. This is why Scuba divers communicate by hand signals.
Yes... because the detection of sound waves transmits pressure waves more efficiently in water.

No. Just the opposite.
helium is less dense than air. :) so helium will float better than air
the answer is sound energy because you have a vibrations in your ear to hear
You would then hear some sound sooner than others.
Yes, solids transmit sound better than gases because their molecules are closer together.
-- The answer regarding air is "Yes". This is a large part of the reason thatyou're able to hear someone talking who is sitting or standing next to you.-- The answer regarding water is "Yes". That's a large part of the reason thatwhales and dolphins are able to communicate with each other.
because air is thiner and water has monicules
Because water conducts sound waves much better than air does.
Sound moves faster and further in water than air, so it would seem like it must have something to do with the receiver. I'm guessing, but I'd guess it's because the eardrum evolved to hear sounds in air. Underwater you don't hear using the eardrum, you hear by way of bone conduction which apparently doesn't let you hear normal sounds as well as the air/eardrum method.
They can hear more, but not better. Because of the density of water, vibrations are changed in pitch, and may be muffled and garbled. Since clarity is the most important factor in hearing, underwater communication is mostly done by hand signals instead. On the other hand, sound moves more quickly underwater, and as a result you can hear from a greater distance. Things can be heard from a lot further away and/or are louder than in air. Unfortunately, because of the higher speed, and reflections from the bottom, sound direction is almost impossible to determine by ear.
I live on a lake and swim quite often. When you go underwater and a boat goes by a 1/4 mile away, you can distinctly hear the prop and engine whirring. Also, the boat sounds much closer and louder than it does above water because sound travels better in water than in air. This is because it is more dense than air.
Whales can generally only hear sounds that are made underwater. They have very good ears, because they 'talk' to each other using grunts and squeals over long distances. Sound waves travel extremely well in water . . . much better than in the air.
Sounds, which are nothing more than vibrations, can actually be heard better and further underwater than in air. So I would think frog's ears would be useful both underwater and sitting on land, to detect noise/vibrations of predators and to detect mates.
cause its easier for sound waves to travel through air than through liquid
because the water is a liquid and air is a gas. so you can hear way clearer in the air because it wanders around and when it's in water it doesn't.it's like a solid but absorbs the sound Sound waves travel faster in water than in the air and their is less attenuation (loss of loudness) for the same distance traveled so it sounds differently to the ear where we re used to hearing noises through air. Also their may still be some air in the ear canal and the sound waves switching from water to air (in the ear) to the ear drum can result in distortion.
Yes
Water is denser than air so the pressure is much greater underwater than it is in the air. Ascending 20 meters (50ish feet)underwater is about the same amount of pressure as like 1000 feet in the air
Yes. When you're underwater in the pool, you can hear the lifeguard's whistle. The vibrations in air do set up vibrations in the water when they hit the surface.
