The Basic Properties of Sound 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.

When I think about pitch the first things come to mind are instruments. This reminds me in middle school if you wanted to a part of the band, you got to test each instrument. I always had a fascinating with a flute, which had high a frequency and high pitch. Another instrument was a trombone; this had a low frequency and low pitch. This helped me understand the difference between pitches.

Sound waves are nothing more than an energy transfer through a medium be it through a liquid, solid, or a gas. Sound pressure or intensity is measured on logarithmic scale in decibels dB which increases on an order of magnitude. For instance a quiet conversation would be around 30 dB and whereas the human pain threshold would be just over 100 dB. While the pitch or frequency of the sound is measured in hertz or Hz, the higher the hertz the higher the pitch of the sound and vice versa (Hildebrand, 2004).

Pitch: Auditory experience corresponding primarily to the frequency if vibrations, resulting in giver or lower tones.

An audio engineer is responsible for the operation of the soundboard and other equipment in the recording of music, words, sounds, or any combination of such material. There are several types of engineering positions available in today's studios. In large studios, there are usually several engineers, each with the own duties and contributions. There are recording engineers, recording assistants, set-up engineers, maintenance engineers, and even mix-down engineers in some cases. In smaller studios the engineer is usually responsible for all of these duties. As a rule, the engineer should be able to set-up, use, and fix the equipment they work with.

Specific Purpose: My audience will learn why music is healthy and beneficial to your health

In 1965 Robert Wise presented the world with his smashing box office hit film, The Sound of Music. Over time it has become known as one of the most loved and well-known musicals of all time. Shortly after its release it won many Academy awards: Best Picture, Best Director, Best Sound, Best Adapted Score, Best Film Editing, Best Film-Musical, Best Color Cinematography, and Best Costume design (Freiden par3). The movie is based upon the true story of the VonTrapp family and allows its audience to relive their family experience as well as their flight from Nazism just before the outbreak of World War Two.

Musicians know that all vibrating objects make sounds. Frequency measure how many times a string vibrates up and down. If a musician changed the length of the string, it also changed the frequency. High frequency will always equal a high pitch. When an octave is increased the frequency will double. Pythagoras discovered different sounds could be made with different weight and vibrations. Due this discovery, they also realized pitch could be controlled by the length of the string.

Musical instruments have played many major roles in helping with the construction of many societies around the world today. Many people do not realize what musical instruments have been responsible for and how they have helped shape the world today. There have been many instruments that have helped create and sculpt the world, but one instrument that I want to inform readers about is the trumpet and where it came from, as well as how it has changed over many years. The point that I am arguing is the fact that many people do not know where the trumpet has come from and how it has affected society.

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

Specific Purpose Statement: To persuade my audience that IF they choose to support a children’s charity, to support St Jude Children’s Research Hospital.

To describe the concept of equal loudness regardless of frequency, the unit phon was developed. Each curve of the equal loudness contours defines a single phon level. For example, the curve that is 40 dB SPL at 1 kHz is defined as 40 phons; 40 phons at 10 kHz is therefore approximately 50 dB SPL and at 100 Hz slightly more than 60 dB SPL. Phons and decibels SPL are the same for a 1 kHz tone — an increase of 10 phons is equal to an increase of 10 dB at 1 kHz, but it may be more or less at other frequencies.

This paper explores multiple studies on the many listening barriers in communication. Specifically, this paper focuses on a study done about the frequent listening barriers and how they can affect listening effectiveness. In addition, It discuses the many individual listening barriers. It explores six major listening factors that come from the multiple listening barriers. The main study this paper revolves around is conducted by Steven Golen (1990), conducted with university students and their opinions of frequent barriers to effective listening. The study explores the most frequently encountered listening barriers in communication.

“How can I be proud of my Jamaican roots, when my ancestors had been slaves”? This question asked by a woman with Jamaican roots followed British novelist Andrea Levy for a long time. She wondered how anyone could be ashamed of his or her legacy and thus the foundation of her book, The Long Song, was laid. However, writing the book was a more difficult task than presumed. Levy considered many things at the preliminary stage of the book as she knew that she didn’t want to write yet another historical novel about slavery. This is the reason why she chose to write the “behind the scenes”-essay, The Writing of The Long Song. Herein she elaborates and discusses the process of writing her book and raises important
