Physics Tutorial: Sound as a Mechanical Wave [1]
Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound
The basis for an understanding of sound, music and hearing is the physics of waves. Sound is a wave that is created by vibrating objects and propagated through a medium from one location to another
As discussed in the previous unit of The Physics Classroom Tutorial, a wave can be described as a disturbance that travels through a medium, transporting energy from one location to another location. The medium is simply the material through which the disturbance is moving; it can be thought of as a series of interacting particles
Anatomy of an Electromagnetic Wave [2]
Energy, a measure of the ability to do work, comes in many forms and can transform from one type to another. Examples of stored or potential energy include batteries and water behind a dam
Mechanical waves and electromagnetic waves are two important ways that energy is transported in the world around us. Waves in water and sound waves in air are two examples of mechanical waves
Matter that waves are traveling through is called a medium. Water waves are formed by vibrations in a liquid and sound waves are formed by vibrations in a gas (air)
Science World [3]
Understand how our inner ear contributes to hearing.. When an object vibrates, it causes movement in surrounding air molecules
This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy
As it is disturbed, each molecule just moves away from a resting point but then eventually returns to it.. If your ear is within range of such vibrations, you hear the sound
SOUND AND HEARING [4]
Sound is a mechanical wave of frequencies within the human audible range. Generally, a mechanical wave is an oscillation that travels through space, accompanied by a transfer of energy
The deformation reverses itself owing to restoring forces resulting from its deformation. For example, sound waves propagate via air molecules colliding with their neighbours and when air molecules collide, they also bounce away from each other (a restoring force)
Therefore wave motion transfers energy from one point to another with no associated mass transport. Mechanical waves require a medium for the transfer of energy to occur (solid, liquid or gas) and do not propagate in vacuum
What is a sound wave, and what do sound waves move or travel through? [5]
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound.. Sound waves are created by object vibrations and produce pressure waves, for example, a ringing cellphone
The pattern of the disturbance creates outward movement in a wave pattern, like sea water in the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source.
The Roman architect and engineer Vitruvius and the Roman philosopher Boethius each theorized that sound may move in waves. The origin of the modern study of sound is attributed to Galileo Galilei (1564-1642).
Sound Waves [6]
In physiology, sound is produced when an object’s vibrations move through a medium until they enter the human eardrum. In physics, sound is produced in the form of a pressure wave
While the physiological definition includes a subject’s reception of sound, the physics definition recognizes that sound exists independently of an individual’s reception. You may recognize this section from our blog post, “What is a Sound Wave in Physics?” Keep reading for a more in-depth look at sound waves.
You’re likely to find the sounds produced by a piano player soft, audible, and musical. And while the sound of road construction early on Saturday morning is also audible, it certainly isn’t pleasant or soft

Nature, Speed, Reflection Of Sound With Formulas [8]
Often we hear sound when we talk to people, listen to music, play a musical instrument, etc. But have you ever wondered what sound is and how it originated? In this article, let us find answers to all these questions.
The medium in which it propagates can either be a solid, a liquid or a gas. Sound travels fastest in solids, relatively slower in liquids and slowest in gases.
The reception of sound pressure waves and their perception by the brain.. A sound wave is the pattern of disturbance caused by the energy travelling away from the source of the sound
Openphysics/Sound [9]
Ultrasound and the Doppler Effect Ultrasonic waves (ultrasound) are sound waves with a frequency greater than 20 000 Hz (the upper limit of human hearing). These waves can be used in medicine to determine the direction of blood flow
The sound waves can travel through skin and tissue and will be reflected by moving objects in the body (like blood). The reflected waves return to the flow meter where its frequency (received frequency) is compared to the transmitted frequency

Making Sound Waves [10]
How well do you know your eardrums? You probably know that your eardrum is an essential part of your ear, allowing you to hear the world around you. But why do we call it a drum? It turns out that calling it a drum is a very accurate description of what your eardrum looks like—and what it does inside your ear
When you do this, you can feel the vibrations moving through the drum material. Our eardrums work in a similar way, but instead of from the beat of a drumstick, our eardrums vibrate in response to sound waves hitting it
What we experience as sound is actually a mechanical wave, produced by the back-and-forth vibration of particles in the air (or whatever medium is around our ears—remember sound travels through water, too!). To understand this, imagine (or try) clapping your hands underwater
Wikipedia [11]
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.[1] Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans
Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Different animal species have varying hearing ranges.
A scientist who works in the field of acoustics is an acoustician, while someone working in the field of acoustical engineering may be called an acoustical engineer.[2] An audio engineer, on the other hand, is concerned with the recording, manipulation, mixing, and reproduction of sound.. Applications of acoustics are found in almost all aspects of modern society, subdisciplines include aeroacoustics, audio signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, psychoacoustics, speech, ultrasound, underwater acoustics, and vibration.[3]
13.1 Types of Waves – Physics [12]
By the end of this section, you will be able to do the following:. – Define mechanical waves and medium, and relate the two
The learning objectives in this section will help your students master the following standards:. The student knows the characteristics and behavior of waves
What do we mean when we say something is a wave? A wave is a disturbance that travels or propagates from the place where it was created. Waves transfer energy from one place to another, but they do not necessarily transfer any mass
Sound – visualising sound waves [13]
Sound is a form of energy that is caused by the vibration of matter. Sound is transmitted through waves, which travel through solids, liquids and gases
If we could see the molecules that make up the air around us, we would see sound as a series of more and less dense areas of air that are moving away from the source of the sound at about 340 metres per second. We say sound is a wave because the air molecules move back and forth while the sound travels along
It is difficult to draw compression waves, so waves are generally represented as transverse waves for simplicity. The dense areas of the compression wave are the peaks of the transverse wave and the sparse areas are the troughs.
How to see a sound wave [14]
You can see the swell, a mechanical wave that propagates on the surface of the water; you can also see an earthquake; but can we see a sound wave? And what if it were possible? We will see that this seemingly simple question opens up exciting educational scenarios for using the inquiry method with students.. Experience shows that we cannot see a sound: whether the music is loud or not, whether a note is high or low, the visual appearance of the world around us does not change according to the sounds that are emitted around us
A sound is created by an object vibrating in a medium such as air or water. The movements of the object compress then relax the immediate medium around the object, for example the air, and these pressure variations are progressively propagated in the rest of the medium, this is the sound wave
Leonardo da Vinci, the first to have glimpsed the mechanism of the swell, made this analogy: “We see in the month of May running through the countryside the undulations that the wind makes in the wheat, and yet the wheat has not not moved”.. Why can’t we see a sound? It is sometimes said that you cannot see a sound because the air is transparent
Sound Energy: Everything You Need to Know [15]
Can we use sound energy to turn noise into forms of energy? Sounds crazy, but we discover different types of energy all the time — especially when it comes to renewables — and sound energy is just another kind.. Around the world, it’s hard to find somewhere that noise is not part of the landscape
There are many different types of sound ranging from the audible to the inaudible.. Sound sources may be pleasant or unpleasant to the human ear, depending on loudness, different pitches, types of sound, sound source, and sound intensity
So what is sound energy, exactly? Sound energy is turning sound into electricity. Though the science of turning sound energy into electricity is still emerging, it has been done
