Abstract
The following paper discusses acoustics signals that detect the presence and location of commercially useful fish, map the ocean floor to establish the safest paths for supertankers, explore the earth?s geological formations and discover oil deposits in the ocean floor.
From the Paper
"At a bottom of the permanent thermocline or below it, water temperature is uniform. Here, the pressure of the water column due to the depth takes over. The sound speeds then increase on account of increase in pressure. (Pacific) The deep sound channel axis is between 600 and 1,200 m below the sea surface at low and middle latitudes. This is deepest in the subtropics and come to the surface in high latitudes, where sound propagates in the surface layer. (Pacific)
Sound waves can be ?trapped? in the deep sound channel and propagate in long distances. This is because these waves go through little attenuation beyond that, and this is due to geometric scattering or spread as well as minor volume scattering in water."

Abstract
The following paper discusses elements such as room size, room composition, room shape, and the location of the listener and sound source, when designing theater acoustics. Finding the ultimate impulse response with testing is also discussed.
From the paper:
?It has been considered that gross errors in concert hall design are rarely due to use of the wrong absorption coefficients, as most of the materials used are highly reflective. A theatre audience first hears sound generated from the source. Then they will hear attenuated bounces of sound off the walls. The sound is again and again reflected off the walls, resulting in total reverberation of the sound. In a large room such as a theatre, reverberation time can be as long as four seconds.?

Abstract
Amyotrophic Lateral Sclerosis (ALS) is a neuro-degenerative disorder producing deterioration of the motor cortex and motoneurons of the brainstem and spinal cord. In particular, patients are affected by the vulnerability of the cranial motoneurons that assist speech and swallowing. The disease usually leads to death in 3 to 5 years due to respiratory complications.

Acoustic Phonetics, 2002.
A look at the developing field of acoustic phonetics, with a focus on the help it brings to those with disabilities.

Abstract
The field of acoustic phonetics studies the transmission of speech sounds through the air from the speaker to the hearer and measures and analyzes the movement and vibration of the air. It defines categories of speech sounds that are used to form distinctions between words in languages. This paper shows that by looking at the anatomy and physiology of speech and analyzing sound waves and mechanisms, we can create many interesting and useful applications in the field of sound. It shows how we can look at the influence of context on speech sound production, as well as develop applications to help those with disabilities that impair their communication ability. The paper shows how acoustic phonetics is applied to communications disorders and mentions the problem in this field in which all the early sound spectrograph and wave-form editors focused on analysis of the male voice spectrum, leaving out disabled women.
From the Paper
"In theory we can talk about phonetics without reference to phonology?which is the actual pronunciation of words and sentence, the regular patterning that occurs, and why the sound ?ing? used at the end of the word ?sing? for example, never occurs at the beginning of a word. But in fact, we can only truly define phonology in relation to phonetics, which deals with all speech sounds. Phonetics has taught us that although humans are capable of producing an enormous number of speech sounds, each language uses only some of the sounds available, and no two languages have exactly the same set of speech sounds. Even more interesting, each language organizes and makes use of sounds in its own particular way."

Abstract
The violin is both a work of art and a musical instrument. Its complex and often disputed history is explored in this paper. The paper begins by introducing the instrument and then discusses a brief history of its development. The violin's construction is examined as well as its sound, tone and acoustics.
Introduction
History of the Violin
Violin Construction
Sound, Tone and Acoustics
Conclusions/Analysis
From the Paper
"The violin is one of the most remarkable and at the same time complex of string instruments. One cannot argue that the violin of today is both a work of art and a musical instrument that must be appreciated for its complexity and brilliance. The quality of sound and tonal differentiations produced when playing depend on many factors, including the construction of the actual instrument itself and the skill of the player.
The history of the violin is long and highly debated. There are those that claim the violin has been in existence since early biblical times, whereas others argue that the true violin as we know it today did not emerge until the mid 17th to eighteenth centuries. These differences in opinion are due largely to one's interpretation of the violin."

Abstract
Discusses various hearing aid devices. Earliest forms of hearing aids and their development. Direction of future hearing aid design. First techniques and devices to combat hearing loss. Ear trumpets, the acoustic throne. How acoustic hearing aids work. Electronic and carbon hearing aids. Vacuum hearing aids. Transistors. Implant controversy.
From the Paper
"Vision and hearing may be the most critical of the five human senses in terms of everyday existence. Certainly being completely deprived of either of these two senses makes it difficult to even move about one's environment safely, and communication is made much more difficult if one lacks vision or hearing. Both senses tend to deteriorate with age, and both can be disrupted by accident, illness or from environmental factors. In the case of aging and even environmental factors (such as ongoing exposure to loud noises), the senses deteriorate over time, but with other factors, such as illness or accident, the sensory loss can be immediate. Humankind has developed various devices for assisting those who lose visual or auditory acuity, and individuals begin compensating for the loss of these senses without artificial devices..."

Concert Halls and Listening Quality, 2002.
An overview of the design of concert halls in order to enhance listening quality.
650 words (approx. 2.6 pages), 3 sources, $ 26.95
»
Click here to show/hide summary
Abstract
This paper is on acoustics and listening quality. A number of factors go into the design of concert halls and rooms to enhance their potential for listening quality. The sheer number of these factors have meant that designers face a number of difficulties in designing their listening spaces. As this essay will argue, the design of spaces to enhance their listening quality depends to a great degree upon a variety of these acoustical factors.

Soundscape and Impressions of French Asia, 2005.
An analysis of Murray Shafer's involvement in the World Soundscape Project.

»
Click here to show/hide summary
Abstract
The paper refers to Murray Shafer's Soundscape Project and the emerging field of psycho-acoustics, in reference to Western sound impressions of Asia, a familiar device of occidental film and other arts. Reference to Loti's "Mme Chrysanthmeme" and the author's rejection of Japanese sounds and music, en route to discussion of what is seen as "Asian" music or sound in treatments of French Indochina and Vietnam. The theory in the paper refers to Orientalism, ethnocentrism and Eurocentrism of the 19th century, as these are argued to prevail.
From the Paper
"Murray Schafer explains the significance of music and sounds in reference to his 1970s involvement with the World Soundscape Project at Simon Fraser University, and informal experiments noting tastes according to culture, or denoting culture, and sounds that appeal to persons of one background, but not another. (1994, 146-149) His ideas are interesting to contemplate in terms of how sound is used in film, for instance, to infer a particular effect. The viewer need never have set foot in Asia, yet effects and music summon cues that 'speak' to the viewer's sense of it."

Construction Projects, 2002.
Compares the Golden Gate Bridge and the Eurotunnel to determine whether they were successful or unsuccessful construction projects.

Abstract
When considering the variables that influence the outcome of a major construction project, it is important to recognize that a project is nothing more or nothing less than a one-time job that has definite starting and ending points, clearly defined objectives, scope and a budget. In order to determine what distinguishes a successful major construction project from one which fails, two projects are compared in this paper. The first is the Golden Gate Bridge, completed in 1937, under conditions which would try the patience and test the competencies of its designers, builders, and sponsors. The second construction project is the Eurotunnel, also known as the Chunnel, the underwater tunnel linking England and France. Completed in the early 1990s, the Chunnel stands as an excellent example of a major construction project which was ultimately successful in the sense of structural integrity and to an extent, customer satisfaction, but a miserable failure in terms of scheduling and massive budgetary or cost overruns.
From the Paper
"In 1989, Andrew Phillips (1989) reported on major problems which were seriously disrupting the completion of the project. Initially, the engineers and managers faced technical obstacles that delayed start-up and construction of the project. Though these obstacles were overcome, soaring costs had added approximately $1.9 billion to the cost of the tunnel itself. To make matters worse, Phillips (1989) maintains that the estimated costs of a planned high-speed rail link between London and the Chunnel?s English terminal near Folkestone, more than doubled. In 1987, the company building the tunnel put the total cost of the project at $9.1 billion - this was raised to $10.2 billion in 1988, and in 1989, analysts predicted that the cost of the Chunnel would ultimately reach $11 billion."

Sound in Ancient Greek Theater, 2005.
An examination of sound and audibility in the theaters of Ancient Greece.
2,038 words (approx. 8.2 pages), 5 sources, MLA, $ 64.95

Abstract
This paper examines how the acoustics in Greek theater spaces have ultimately proven to play a vital role in spectatorship and performance. It looks at how theater spaces and design were a necessary construct at the time in compelling audiences to become absorbed into the fullest theatrical experience possible, while simultaneously obligating actors to deliver the finest deliverance of dialogue.
From the Paper
"Whether by accident or design, there exists some fundamental objections to the theatre spaces that are the foundation of the acoustics. For example, often noise from any section of the auditorium can be distinctly heard in the others. A rowdy audience therefore could ruin the performance. We may recall the tradition, dating from the early days of the theatre before the buildings had assumed permanent stone form, that audiences drummed their heels on the wooden benches to show their disapproval of a play. In a theatre with naturally good acoustics, this must have been devastating. It illuminates the necessity, both for tragedy and comedy, of embodying additional attention-holding devices, and the dangers of allowing a huge crowd to be distracted."

Abstract
This paper examines the functional, operative and practical aspects of "Stomp" (a physical theatre and musical performance) and "Live Earth Concert" (a series of worldwide concerts held on the same day). It explains and compares different facets of these two performances, including the venue; atmosphere; musical aspects; lighting and sound enforcement. The writer reflects on the overall performances and notes that most people who attended both performances enjoyed "Stomp" (the relatively low budget unique creation) more. The writer concludes that both events were worth the price of the tickets, as "Live Earth Concert" was a great opportunity to see several artists performing on one stage and "Stomp" was a purely entertaining and exclusive show.

Conclusion
From the Paper
"A concert or as some colloquially call it a 'gig' or 'show' is a performance, that has music as the central entertaining premise. The performers and entertainers such as solo artists or bands, aim to generate a vigour, power and energy that in a sentence leave their audiences in rapturous admiration and awe at the vertical depth and wide coverage that they are able to generate in just a short space of time. The musical masterpiece 'Stomp' which is currently being staged at Vaudeville Theatre in London; and the benevolent global 'Live Earth Concert', which was held on the 7th of July 2007 and had Wembley Stadium London as one of its many venues; model two such concert performances."

Prosody, 2006.
An overview and definition of the concept of prosody.
4,050 words (approx. 16.2 pages), 6 sources, $ 160.95
»
Click here to show/hide summary
Abstract
This paper discusses the concept of prosody, pointing out that it is a very difficult concept to define as it interrelates with other corresponding variables and is perceived differently according to the individual. Also, though it is acknowledged as a definite and highly influential part of language, definition and speech perception research on the topic has to date been more limited than one might think. The paper explains that most traditional research has focused on describing the acoustics of prominence and phrasing in restricted speaking styles without revealing knowledge as to how auditory and visual signals actually interact to signal communicative functions in expressive speech.
