Do sound waves travel forever

Answer 1

Sounds waves as they spread out get weaker and weaker until they just about disappear. Theoretically there will always be some small amount of sound still propagating forever but it will be so weak that it would be unmeasurable. Even if we had the ultimately sensitive listening device and could still detect (hear) sounds from long ago there would be so many other old sounds mixed together that all we would hear would be just noise, probably sounding like a hiss or a humming sound.

Answer 2

No. We don't generally say that sound disappears. Sound will dissipate as its energy is absorbed by the things it comes in contact with (though some of that energy may be reflected). That includes the air through which it is traveling. Eventually, all its energy will have been absorbed. Sound does lose energy as it travells through matter, and will eventually not have enough energy left to continue travelling.

Answer 3

No, they dissipate, broken up by other waves, or simply by growing to attenuated.

They dissipate as the wavefront continues to travel farther way and the density of the energy will spread farther and farther away until it is essentially zero.

Answer 4

Sound waves will eventually dissipate and lose energy as they travel through a medium due to factors such as air resistance and absorption. This leads to a decrease in the amplitude of the sound wave over distance, eventually resulting in the sound becoming inaudible. Therefore, sound waves do not travel forever.

Answer 5

because if they didn't fade away the sound would go on for ever !!!!!

Answer 6

`No sound waves are not matter .They can travel through matter but no sound waves are not matter

Answer 7

Yes, theres water and the beach will always be there, so waves will last forever. Also because the earth is 75% water so waves will always be there
