How does sound cause physical damage to an object?

Question

Is it Sci-Fi that sound can cause damage to an object?

Answer 1

Its simple but I see no one got to the answer correct.

Atoms , vibratian , frequency and substance
***********************************************
Everey object is made of atoms at the most basic. And these atoms of any object exisist in the form of molecules that is configured in various different bonds. Unless under 275 K tempearature else all atoms contans energy thus it vibrates and therefore indirectly makes all molucules of any material or substance to vibrate as well. And remember anything that vibrates can be measured in what we call frequency with units in Hertz.

Sound wave energy
***************************************************************
Now sound is a form energy that travels in the form of waves - It can be represented by frequency of the vibrating sinosodial wave.

resonance and Impedence
******************************************************
when A vibrates at 30 Hz and with 6000 j energy then if it meets B that also vibrates at 30 Hz and at 6000 j then since both is having the SAME FREQUENCY then RESONANS occur. and the combined vibration would be far far far more gigantic.


So the theory is
+++++++++++

when a sound with certain frequency hits an object at wich the objects molecules natural vibration is at the same frequency of the sound that hit it then a RESONANCE occur and a violent huge wave of vibration is crreated and this energy is taken by the molecules of the object and due to uneven vibration within the object causes the object breaks.

eg of events : oprah singer who creates the sound that vibrates with the same frequency of the glass molecule and thuis resonance occur and breaks the glass.

another famous urban mystery says that the bridge of river kwai had cracks after soldiers march through the bridge because the frequency of the soldiers boots hitting the bridge was equavelant to the vibration of the molecules of the bridge hence resonance creatd and the bridge cracks.

hope thats help

have a nice day

Answer 2

Sound is a vibration, all things have a vibrational frequency. So, in simple terms, if a lorry goes past your house, the house will vibrated. If a singer pitches the voice at a high enough frequency it can shatter a glass, the molecular chains are not sufficiently strong enough to hold together and the resonance will destroy the object.

Answer 3

Yes it can, the sound will make the object vibrate and if the sound reaches the right pitch an object can vibrate so much it shatters or cracks, there is a scientific explaination for it but can't remember how to phrase it.

Answer 4

The sound waves hit the resonant frequency of the molecular structure of the object causing disruption of molecules and damage to and even shattering the object...particularly the crystal structure of glass.

Answer 5

what everyone fails to remember here is that air actually has mass - and it is the vibration of this mass (caused by a sound source) that gets transferred to another medium ie a gunshot through the air to your eardrum or a thunderclap through the air to a car body vibrating it so much that the alarm goes off. in effect the sound source causes the air to vibrate - this vibration is in ever increasing circles the distance that you can hear sound is governed by the frequency, pitch, and source type and this decreases by about 6db every time distance is doubled - if a bomb goes off near to houses its mostly the shock waves in the air that break the windows rather than the shrapnel.

Answer 6

Sound is energy. If you stand behind a jet engine when it's taking off it will sure as hell damage your eardrums. Just like when an opera singer hits the high note and shatters a wine glass.

Answer 7

Sound is due to rapid changes in air pressure.The louder, the greater is the difference between topmost pressure ann lowest pressure.I dont know whats to stop it breaking up any thing ;in particular I'm sure you know that sound at the right frequency can break a wine glass.

Answer 8

No, an extremely loud sound is capable of breaking objects especially glass.

Not sure why though. I think it because of the molecule displacements in the air.

Answer 9

well sound makes atoms move, so you could bombard an object with sound waves, if there's enough power in the wave, even damage the object.

Answer 10

Sound can actually cause damage to an object. myth busters proved it is possible to break a glass with your voice. sound can also screw up microphones.
