Kinetic energy is the movement energy of an object. Kinetic energy can be transferred between objects and transformed into other kinds of energy.

The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.

Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms.

5 Forms of Energy

• Electrical Energy.
• Light Energy.
• Mechanical Energy.
• Sound Energy.
• Thermal Energy.

The primary sources of energy in the environment include fuels like coal, oil, natural gas, uranium, and biomass. All primary source fuels except biomass are non- renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy. There are 6 more fundamental concepts.

Examples of Sound Energy

• An air conditioning fan.
• An airplane taking off.
• A ballerina dancing in toe shoes.
• A balloon popping.
• The bell dinging on a microwave.
• A boom box blaring.
• A broom swishing.
• A buzzing bee.

Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

Sound energy is the physical vibration waves that travel through the air to reach the ears signaling the brain to interpret incoming sound(s).

It helps us to communicate with others. By sound, we can understand the context of the words spoken. Sound can help people to protect themselves from danger such as the sound or horn of the train and other vehicles warn people to give way etc. Sound is a medium of entertainment.

What are the applications of sound?

• Sonar is used in navigation, forecasting weather, and for tracking aircraft, ships, submarines, and missiles.
• Sound finds many applications in entertainment electronics, radio, cassette, etc.
• Sound is very useful in communication.

Answer: Acoustic instruments, Electrical instruments, Living beings like animals and birds using their vocal cords, Man-made sources like machines, any vibration caused by wind are five sources of sound.

It communicates messages in many different ways, soothes the mind and also helps relieve stress from our everyday lives. It is a sound that is in a controlled and tuned type of matter, relying on frequency and pitch of the voice.

Sound is important because it engages audiences: it helps deliver information, it increases the production value, it evokes emotional responses, it emphasises what’s on the screen and is used to indicate mood. Sound adds emotion and connects people to what they’re seeing.

Audio can be used to enhance multimedia applications in a number of ways, for example in delivering lectures over the web, music used to add interest and emotion to a presentation, and other non-speech audio used as part of a general interface.

We use sound mainly to communicate with each other. In SONAR(Sound Navigation and Ranging) sound is used to determine the position of a submarine are the depth of the sea at any place. There are many uses of sound but which is good for humanity are as: 1 – In navy patrolling devices , Sonar system uses sound as tool.

Today’s Use of Sound Technology

• Cellular Telephone.
• Motion Picture.
• Telephone.
• C.D.’s Televisions.
• Phonographs.
• Electronics.
• Hearing Aids.
• Video Tape Recorders.

Ultrasound waves are used to detect objects. A ringing telephone, a honking horn, and the sound of a friend’s voice are all reminders of how important sound is. But sound has uses that go beyond communication. People use ultrasound echoes to detect objects underwater or even to produce images of the inside of the body.

Sound travels through materials as a wave of pressure. Although we cannot use sound energy to power our cars or light our homes, we can use sound energy to learn about our surroundings. The simplest and most obvious use of sound energy is for hearing. Humans can hear frequencies between about 20 Hz and 20,000 Hz.

Sonic and ultrasonic weapons (USW) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound; others produce an area field of sound. As of 2021 military and police forces make some limited use of sonic weapons.

Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.
