31+ Sound Energy Examples: Uses And Detailed Facts

Sound energy is produced when an object vibrates, which results in noise. The sound vibrations cause waves of pressure that travel through a medium such as air, water, and wood.

Sound energy is defined as “the movement of vibration through matter”. There must be a medium through which sound travel, it cannot travel through a vacuum and sound energy is normally measured by its intensity and pressure, in special units known as Pascal and decibels.

This post gives you a detailed explanation of such sound energy examples

An air conditioning fan

 Different things in an air conditioning fan can be creating sound energy it could be one of the motors but it could also be air resistance. If push air to another area of the home if the intake is too small motor noise is reduced by quieting the compressor. 

An airplane taking off

When the airplane is take off it causes sound energy because of the exeunt of its heave over the runway with a repute for the act of the wind. Sound energies are played by the aircraft engine which converts chemical energy into mechanical energy while taking off.

A balloon popping

The reason behind the sound energy in balloon popping is the sudden release of pressure, this higher pressure causes bigger bursting. The sudden rupture of stretched rubber contributes to sound.

Sound energy in a microwave

Microwave causes sound energy during operation because the magnetron uses high voltage to generate the microwave frequency that cooks the food and normally emits a low hum however if the magnetron is damaged it may begin emitting high pitched sound energy.

A buzzing bee

The bee cause sound energy by buzzing because the wings of the bee flap very rapidly these wing beads create vibration in the wind near them and cause sound energy.

Fireworks exploding

When fireworks explode we hear the delayed sound energy because the fireworks exploded so well-built up and the speed of light is faster than the speed of sound.

A flag flapping in a strong breeze

Layers of strong breeze start with unequal haste on the two sides of the cotton flag due to it, there will be unequal pressure on the two flags which leads to flapping then sound energy is created.

Meat sizzling on the grill

 When meat is sizzling we have high heat on a grill it makes a sound and turns brown, bursting up with water via oil to prepare a sizzling sound.

A waterfall

Low, high, and medium sound energies are formed in waterfall because waterfall of enormous volume from huge height impact by changing depth of water.

A whistle

Blowing a whistle forces air via the mouth then the air enters the whistle and escapes from a hole on the other end creating audible sound energy in the whistle.

Waves crashing into a rocky shore

Wind and rain form the wave surface, and at the wave, eye edge bubbles trapped under waterfalls onto a hard wall of rock radiate sound energy.

Car brakes squealing

The Brake system works on brake pads and rotor, when we apply to break the pads squeezing on the outside surface pad touches the rotor to create sound. 

A vehicle crashing

When stringent material crashes on a harsh floor if two vans bombard each other hence it vibrates and creates sudden sound energy.

A car door closing

The car door makes a sound when close because of spare lube on the sub latch roller axle..

A vehicle engine

If the car is running louder than it used to make strange sound energy due to a damaged muffler.

A car horn honking

The horn contains a copper coil in which current flows through it creating a magnetic field then the horn flop inside the midriff creates sound energy.

A siren

Siren makes sound energy because they have high-efficiency loudspeakers with pursued magnifier and tone generation imitate the siren sound.

Tires squealing when racing

Racing produces sound energy in tires because of Doppler effects so if a tire hits a rough surface during racing is very fast hence sound is created.

A signal

In the microphone, the signal makes sound energy because there is air pressure variation that generates electrical signals that produce sound.

A jackhammer

Rock drilling using a Jackhammer create sound energy because compressive strength increase air pressure and scraping of rock decrease hence requiring high pressure, and thrust creates sound energy.

Smoothing wood with sand paper

It creates sound energy because sandpaper is wrapped around the block which rubs on a block of wood with even pressure create sound.


When we cough we hear the sound because our airways are narrow during coughing which creates sound energy.


Muscles between the ribs initiation to persevere vast, hardened contraction knead air out and makes sound energy.


During sneezing air evades from the nose hence sound energy is created which depends on lung capacity.


During belching, in superior alimentary canal elevation pressure air preparing structure, and behind throat vibrate and causes sound energy.

Baby crying

The sound energy is created when a baby cries because the baby workout to authority the air that comes from their lungs and uses vocal cords which put a plinth for speech.

A xylophone tinkling

Xylophone consists of a set of tuned keys of a piano when the hammer assert the bar creates a shudder which creates waves making sound energy.

Electric guitar whining

Bend the string with the finger on the guitar which creates a whiny kind of sound energy because too much pressure can bend the string out of tune.

A train moving on the tracks

Train wheels roll over on tracks creating sound energy so when trying moves vibrations are created because of hardness and inconsistency on the wheel and train surface.

Uses of sound energy

Battle fields

 Sound is used as a weapon in the war field, for example, sonic weapons are used to perpetrate adversary and acoustic equipment which uses the effect of sound to cause potentially lethal disaster.

Shipping industry

Sonar sound navigation and ranging are used in the shipping industry for detecting submerged objects through sound waves reflected by objects and also locating enemy ships.

Music industry

The music instruments and amplifier produce sound as music which is used in healing the body by deletion unconstraint and body aches.

Cellular telephone

The telephone uses sound energy for communication in which sound energy is transported in the midriff and converted to electrical energy and another phone receives this electrical energy then converted to radio waves for intimation.

Motion picture sound recording

The photographic scene uses a unique system recording that gives the highest flexibility in the soundtrack but motion picture sound recording uses a couple of systems to separate the image from the soundtrack so sound can perfectly be matched ocular.


In television, electrical energy from the battery is converted to visible light, and television consists of a camera that steers a depiction and sound into a denotation, the transmitter sends the logogram over the air, and the receiver captures the logogram and orders it back into picture sound.

The piezoelectric generator is a power generating device it contains a transducer that creates noise and causes a vibration transducer to convert this vibration into electrical energy. 

Hearing aids

Hearing aids are designed to dilate sound which improves the sage language in a noisy environment. A small computer in a hearing aid turns up incoming sound signals this accommodates for person’s hearing loss.

Audio tape archivist

Audiotape archivist is a sound recording and reproduction device it uses magnetic tape as storage to move to tape-record fluctuating signals in a document to the audio signal.
