What is a sound wave? A sound wave is produced by a mechanical vibration, such as a tuning fork. The vibrating object causes the surrounding medium, such as air, to vibrate as well.The wave travels through the medium to a detector, like your ear, and it is heard.As with any type of wave, a sound wave is also described by it's wavelength, amplitude, period, and frequency.
WAVELENGTH is the distance from one point on the wave,
to the next identical point, or the length of one part of the wave.
AMPLITUDE is the distance from the midpoint to the place of maximum displacement.
FREQUENCY is the number of cycles that occur in one second.
It is also the inverse of the period.
PERIOD is the time it takes for a wave to complete one full cycle.
It is also the inverse of frequency.
Sound waves are longitudinal waves that consist of high and low pressure areas called condensations and rarefactions, respectively. Since sound waves are longitudinal waves, the particles of the medium oscillate parallel to the velocity of the wave. The individual particles do not travel along the wave. They only oscillate back and forth and the wave still propagates through them.
The speed of sound depends on the type of medium that the wave is traveling through. In air, the speed of sound is about 340 m/s or 760 mph for a normal spring day. The speed also depends on the temperature of the medium.
The formula used to figure out the speed of sound, in air, on any given day is;
v = 331 m/s + 0.6T
where v is the velocity of the wave, T is the temperature of the air in degrees celcius, 331 m/s is the speed of sound at 0°C, and 0.6 is just a constant. So as the temperature increases, so does the speed o...

... Association, if a the sound of a plane taking off is 1,000,000,000,000 times the threshold sound, and if the sound of a hand drill is 10,000,000,000 times the threshold sound, during which sound would you wear hearing protection?
The purpose of this experiment was to determine whether if the sound is affected when it travels through different length pipes. The method used to do this experiment was created by using 5 different PVC pipes in the lengths of 10, 20, 30, 40, and 50 centimeters. Then, using a tuning fork, sound will be produced on one end of the PVC pipe and measured with a decimeter on the other end. This experiment was recorded using 5 trials for each independent level and the average decibels (dB) for each pipe length were recorded.
“Music is perpetual, and only the hearing is intermittent,” wrote the iconic American essayist, poet and philosopher Henry David Thoreau, a lofty proclamation that inspired my focus to help those with hearing loss through restoration. After a winding journey in search for an academic focus, I discovered that audiology is far more than just aiding deaf or hard of hearing individuals, but restoring balance, managing loss through therapy, and discovering new research techniques that may involve auditory neuropathy spectrum disorder. After arriving at my destination, I also learned that it is my responsibility as a future audiologist to be a leader, to work hard toward achieving a better future for myself, and a better world for humanity at large. This vision drives my aspiration to join the University of South Florida’s graduate audiology program this coming fall, and continue my examination of clinical audiology as a member of your community.
The thermometer’s original temperature before coming in contact with an outside object is represented by T. ∆T/∆t is the average temperature of the digital thermometer. represents the temperature of the heat flowing object. In this lab, the temperature of the air is represented by Tair=T. To= Thand is the temperature of the hand.
Meniere’s disease is a controversial inner ear disorder that has a variety of symptoms. It was first discovered by French physician Prosper Meniere in 1861 after seeing a variety of patients with episodic vertigo attacks. (John Jacob Ballenger, 1996). After a variety of research, Prosper Meniere theorized that the symptoms that his patients were experiencing such as tinnitus and vertigo were not coming from the brain but were actually coming from the inner ear. These findings lead to the research of inner ear disease and its association with inner ear balance disorders. (P.J. Haybach).
Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference. In addition, much like light rays, they can be reflected, refracted, and focused.
As said above, both light and sound waves have to do with interference. In sound, interference affects both the loudness and amplitude. When two waves’ crests overlap, the amplitude increases. The same is true with the troughs of the waves, which decrease the amplitude.
The vibration of the strings of a guitar causes the sound wave, but is not actually what you are hearing. The amplification of the sound wave is what is actually heard. The differences in the tension of the stings and the mass of the strings affect the pitch of the sound produced. The ends of each string are nodes, or where the wave does not travel from its initial position. The note you hear from the string is actually the first harmonic of the wave; other harmonics created when plucking a string form the undertones and overtones of a note. The waves on a guitar string are transverse waves, meaning they travel perpendicular to the original position. The waves are also standing waves, because they remain in the same position.
The Scholar: I think that's more a function of sound wave vibration than anything else.
Sound does however perform much more important, intricate and complex functions than commonly accepted. Sound combines with moving pictures in various ways to create meaning but is diverse and has numerous other uses.
Understanding the frank physics of ultrasound is vital for acute care physicians who present point-of-care ultrasound to make precise critical decisions. Ultrasound is made up of mechanical waves that can send across disparate materials like fluids, soft tissues and solids. It has a frequency higher than the higher human auditory check of 20 KHz.[1] Ultrasound frequency is described as the number of ultrasound waves each subsequent, and health ultrasound mechanisms use waves alongside a frequency fluctuating amid 2 and 15 MHz.[2] The velocity of ultrasound in a specific medium equals the frequency of ultrasound increased by its wave length.[1]
Sound is essentially a wave produced by a vibrating source. This compression and rarefaction of matter will transfer to the surrounding particles, for instance air molecules. Rhythmic variations in air pressure are therefore created which are detected by the ear and perceived as sound. The frequency of a sound wave is the number of these oscillations that passes through a given point each second. It is the compression of the medium particles that actually constitute a sound wave, and which classifies it as longitudinal. As opposed to transverse waves (eg. light waves), in which case the particles move perpendicular to the direction of the wave movement, the medium particles are moving in the same or opposite direction as the wave (Russell, D. A., 1998).
waves are further divided into two groups or bands such as very low frequency (
Sound is produced by vibrations in the air which, in this experiment, came from the hammer. The vibrations are a set of frequencies measured in units of Hertz (Hz). The faster the vibration frequency, the higher the sound will be in pitch. Pythagoras’s 2:1 ratio simply means that both tones are the same however the second tone’s frequency rate is doubled. For example, the blacksmith strike...
