why the shells in the sea shore gives the sea wave sound?

Answer 1

Do you remember trying this as a kid -- Holding one of the seashells you grabbed as a souvenir up to your ear? It seems like no matter how far away from the ocean you are, you can still hold a seashell up to your ear and hear the roar of the waves rolling onto the shore. The best shells for producing this sound are the large, spiral conch shells.

Some people have suggested that the sound you hear from the seashell is the echoing of your blood rushing through the blood vessels of your ear. That is not the case. If that were true, then the sound would intensify after exercising, since your blood races faster after exercising. However, the sound is the same even after exercising.

Others say that the whooshing sound inside the shell is generated by air flowing through the shell - air flowing through the shell and out creates a noise. You'll notice that the sound is louder when you lift the shell slightly away from your ear than it is when the shell is right against your head. However, this theory doesn't hold true in a soundproof room. In a soundproof room, there is still air, but when you hold the seashell to your ear, there's no sound.

The most likely explanation for the wave-like noise is ambient noise from around you. The seashell that you are holding just slightly above your ear captures this noise, which resonates inside the shell. The size and shape of the shell therefore has some effect on the sound you hear. Different shells sound different because different shells accentuate different frequencies. You don't even need the seashell to hear the noise. You can produce the same "ocean" sound using an empty cup or even by cupping your hand over your ear. Go ahead and try it and vary the distance at which you place the cup near your ear. The level of the sound will vary depending on the angle and distance the cup is from your ear.

Noise from outside the shell also can change the intensity of the sound you hear inside the shell. You can look at the shell as a resonating chamber. When sound from outside enters the shell, it bounces around, thus creating an audible noise. So, the louder the environment you are in, the louder the ocean-like sound will be.

The waves wooshed onto the sand.... Onomatopoeia is used to describe words that look like the sound they're describing. for instance, once you rattle a jar of dry beans ... the word 'rattle' describes the sound, and it makes the sound once you're saying the word. further, a balloon will pop ... the word 'pop' makes the sound the balloon does. indexed decrease than are some more effective examples of onomatopoeia ... BUZZ 'hearken to the bee buzz with the help of'. click 'click the button and take a image'. CRACKLE 'hearken to the fireplace crackle contained in the darkish' . FLUSH 'do not ignore to flush the bathroom'. KISS 'a lengthy kiss is something you gained't ignore'. RATCHET 'The bar is a ratchet contained in the gadget'. WHOOSH 'Dave whooshed down the hill'.
