The Uses of Sound Waves Essay

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

The movie The Graduate was a pioneer for the film industry in regards to its use of popular music as non-diegetic sound throughout the film. The Simon and Garfunkel sound track fit in very nicely to set the tone of the film and give the audience clues as to what the characters were feeling. Aside from the non-diegetic sound the diegetic sound was also used very effectively to express character emotions, in particular Ben’s emotions. Ben’s disconnect from society as a whole could have been discovered in the scene in which his father is having him present his birthday present; the use of sound was so strong it would not be difficult to completely understand the scene even without the visuals.

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

Customs and beliefs is what make up a tradition, and tradition is the way one lives their life. In the novel, The Sound of Waves, Yukio Mishima exposed his own view on Japanese traditionalism. Throughout this novel, it is shown that Yukio Mishima believed that Japanese tradition consists of an organized social class, the Bushido code, and going after what one truly believes should be theirs. Mishima illustrated these personal views of Japanese traditionalism through the actions of the Shinji.

In longitudinal waves the object doesn’t exactly follow the waves fully instead the object moves in a back and forth motion while the waves continues to move forward through the object. While in transverse waves the object doesn’t follow the waves as well and just moves up and down in the same position.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

Another example of sound is Hitchcock's use of voice over. For instance, as Marion drives away with the money she ha stolen, she imagines conversations between the people she has left behind and their reactions to her faults. Hitchcock also uses sound, which doesn’t complement the image that we see. Whilst the on screen

In The Sound of Waves, Yukio Mishima creates an exquisite story which has strong idealistic and mythic features. Although Mishima writes of young love and tranquility in The Sound of Waves, his later works are categorized as aggressive and containing violent sexual actions. Even Mishima himself referred to The Sound of Waves as "that great joke on the public" (qtd. in Ishiguro 385). However, one cannot compare this novel to Mishima’s other literary pieces; in order to classify it as romanticized, one must evaluate the usage of imagery, an idealized setting, mythical allusions, and characterizations which establish the romantic-driven qualities in The Sound of Waves.

Sound is a wave, and a wave can be remembered as a medium, carrying energy from one point to another. The sound wave has a resemblance of a slinky in its nature, for many reasons. The disturbance goes from one place to another, carried by the medium. Typically, the medium will carry energy through the air, although it could be any substance like water and steel. There is an original source of the wave; anything from someone’s vibrating vocal chords, or a tuning fork. Then, the sound is transported through the medium through particle-to-particle interaction. If the sound wave is moving through the

It is within this framework that I consider important to study the way in which sound is

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.

A hearing protection device (HPD) is often used as a protective measure in a workplace environment when the sound levels of that environment cannot be decreased and such levels pose a threat to the hearing of workers. An HPD is a safety device worn by individual’s to protect his or her hearing from the harmful effects of sound (Berger, 2003). A variety of occupational environments are known to produce high levels of noise, including factories and military operations. Individuals employed in these professions may be required to wear HPDs to reduce the risk of noise-induced hearing loss. However, certain situations in these work environments require the listener to also be able to hear low-level sounds for safety reasons.

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
