Tinnitus is the perception of sound in the absence of an external source. 10-15 % of the population is experiencing tinnitus. There are different causes such as damage to the inner ear, musculartension and stress. Tinnitus affects many different aspects of an individuals life and often disturbs everyday activities. There are different treatments for tinnitus.

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

Detta examensprojekt innehåller olika frågeställningar gällande hur några av Sveriges främsta hårdrocksproducenter arbetar. Eftersom hårdrock är Sveriges andra största musikgenre när man talar om den svenska musikexporten idag 1, måste det finnas något unikt med de producenter som arbetar med denna genre i Sverige, bortsett från att vi har bra artister, musiker och låtskrivare här. Är det samarbetet mellan artist och producent som gör att en skiva låter bra, eller kanske är det den nya digitala teknikens förtjänst att det går bra för svensk hårdrock? Detta är några av de frågor som kommer att behandlas i projektet.Projektet kommer även att innehålla intervjuer med olika hårdrocksproducenter i Sverige och deras syn på de frågeställningar projektet inkluderar, vilket vidare resulterar i en analys av intervjuerna och producenternas sound. Dessa analyser kommer att vara kopplade till en framställning av viktiga saker man bör ta i beaktande vid musikproduktion av hårdrock.

This paper discusses sound education within school subjects such as music, science, engineering, computer science, and Swedish to classes at the intermediate stage..

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

The aim of this thesis is to describe and compare the cataloguing rules for sound recordings: the rules used by a specialised archive and common libraries respectively. We will put the rules in relation to purposes (the objectives of a bibliographic system) and principles (directives that guide the construction of a bibliographic language). The first question to be answered is in which way the set of rules used by a specialised archive differ from the one used by common libraries. The second question examines if and how the differences can be derived from purposes and principles. The sets of rules studied are KRS (chapter 6) and the Swedish version of the IASA Cataloguing Rules (1999), worked out by the National Archive of Sound and Moving Images (SLBA).

Hemp has been used for textiles for a long time in history until it became illegal to grow in many countries in the 1930s. It is interesting from an environmental point of view because it doesn?t need any pesticides and in most locations it doesn?t need any irrigation either, compared to cotton, which normally requires big amounts of both pesticides and water for irrigation. Hemp is a bast fiber, which means that the fibers are located on the bast of the stem (on the outer layer of the stem). Therefore they cannot be spun directly, they have to be removed from the stem first.

In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements. The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today. The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.

The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

A film can attract all kinds of emotions and moods of the audience through its audiovisual communications and cinematic expression, in which music plays a significant role in both understanding and interpretation of film content.It is interesting to explore the musical significance and the emotional aspect of the film out of a media and communications perspective and visual communications perspective because it?s a subject that belongs to the communications of scientific discipline as film is a media text which is working both as communicative and as audio-visual medium with its expressive aspects.The purpose of this bachelor?s paper is to increase and deepen the understanding of music's function and significant role in context with its reinforcing sense of visual expression in film. More specifically, it aims to explore the musical value of the expressive aspect of the media text in form of film musical Les Misérables (2012), which has been transmedialised from the novel of the same name, referring to the sound, music and song in relation to the film's visual expression.The research questions are at the core of the essay study: "how is music used to reinforce the cinematic visual expression?" and "how can music signify the narrative and highlight the emotional aspect of the film?" The theoretical framework is based on some of the key scholars assumptions such as Michel Chion (1994) and Claudia Gorbman (1987), who share the same theoretical views that the soundtrack seems powerful when it expresses its participation in a scene?s emotional moods as the music follows the scene?s rhythm, the image?s flow and contributes emotional and musical codes of emotions and expressions. According to Chion sound and image interact together to tell a story where sound enrich the image with expressive and informative values.

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

Background: Osteoarthritis is understood to be a common cause of pain and dysfunction in cats; however there are few validated pain assessment methods for chronic pain in cats. In order to design a proper pain questionnaire, it usability need to be tested in both sound and sick cats. Aim: The aim was to investigate the usability of the pain questionnaire ?Lifestyle changes in cats? by compiling the results from the pain questionnaire reflecting the lifestyle in 30 healthy cats and compare it to the results from a clinical examination, as well as proposing improvements and additions to the questionnaire based on a literature review. Material and method: 30 healthy cats participated in the pilot study; the pet owner filled out a pain questionnaire with 16 questions regarding their cat´s behavioral and eventual changes in behavior and physical function. Thereafter the cat walked over a pressure measurement mat and finally underwent an orthopedic-directed clinical examination. The literature was found on Web of Knowledge, PubMed, Sciencedirect, and Google Scholar and also with the help of my supervisors.

Generell anestesi kan ges som inhalationsanestesi eller total intravenös anestesi (TIVA). En förutsägbar anestesi med snabbt uppvaknande och bibehållen vakenhet är en högt önskvärd egenskap oavsett anestesiform. Det råder en klinisk och vetenskaplig diskussion om vilken anestesiform som ger snabbast tidig postoperativ återhämtning. syftet med studien var att jämföra patienters tidiga postoperativa återhämtning efter inhalationsanestesi respektive efter total intravenös anestesi (TIVA). Metoden var en litteraturstudie baserad på 15 vetenskapliga artiklar.
