Given equal power at the sound source - is the amplitude (in pascals) of sound pressure waves greater in water than in air? - What is the mathematical or physical bases of any difference?
Sounds seem louder under water because water is a denser medium than air, meaning that sound waves travel faster and with greater intensity in water.
The loudness of sounds under water can vary depending on factors such as depth and water temperature, but on average, sounds can be up to four times louder under water than in air.
No, not all sounds can travel underwater. Sounds with low frequencies, such as those produced by large mammals like whales, can travel long distances underwater, while high-frequency sounds, like human voices, only travel short distances.
Yes, sounds can change pitch under water. This is because the speed of sound waves is directly related to the medium they are traveling through, so the change in density and speed of sound in water can cause a change in pitch.
The deeper the water, the louder sounds will be. This is because water pressure increases with depth, which in turn increases the speed of sound waves and makes them louder.
