Många av dagens dator och TV-spelsljud är anpassade för högtalaruppspelning, i många fall även flerkanalssystem som 5.1 surround och liknande. Få spel är anpassade för uppspelning genom hörlurar och för att få en bra ljudlokalisering i hörlurar behövs ofta någon form av surroundhörlurar. Vi tror att man kan skapa trovärdig (Riktnings)återgivning av ljud i hörlurar genom bara två ljudkanaler genom så kallat binauralt ljud. Vi kommer i detta arbete att beskriva de faktorer som spelar roll i vår stereohörsel, varför de fungerar samt vilka svagheter som finns i detta system. Vi kommer att skapa ett system för att behandla realtidsgenererat binauralt ljud för spel och beskriva de verktyg vi valt och den generella arbetsprocessen.

The purpose of this study is to find out how some Swedish preschool teacher discussing how children's Swedish colloquial interaction can be enhanced in the free play. In this case where children are aged three to five.My research questions in the study are:-          What type of free play do preschool teachers talk about in relation to children's Swedish colloquial development?-          What do preschool teachers say about child's colloquial interaction?-           How do preschool teachers reason regarding in what environment children?s colloquial interaction occurs?In my study I have used an interview with elements of a visual method called The Diamond. The approach is that the participants in the interview will be enhanced to discussing about a wise certain number of images. These images are then to be ranked accordingly with a specific theme and terms.If a child has difficult to speak, you can take help of  the interest the child has, the child can tell you and the other children what he or she know about the interest.

The education program System design at the University of Kalmar has since it?s beginning been missing a near by studio for it?s students studying towards audio and music. In the choice of examination project I would take upon this task, which was long wanted for the teachers and students at the university?s Musikhuset.Musikhuset became the buyer of the project, and the studio was to be installed at their premises. Unfortunately, the project got jammed by the university?s financial savings calculations, and was due to this delayed in the end for 11 weeks.

The main purpose of this study is to investigate in what ways librarians and schoolteachers can co-operate and combine their professional skills in order to help and motivate children with reading and writing disabilities, and how audio books can be useful in this work. The main source of information is interviews with teachers from ten schools in the province of Scania, southern Sweden. Those teachers, their schools and their local libraries all took part in a project spanning from 1993 to 1996, aiming at increasing the use of audio books in combination with the corresponding printed versions in work regarding the here addressed problem. This study was made with a qualitative empirical method supported by a normative theory belonging to the new institutional theory school. There are no statistical conclusions in the report.

Abstrakt Sound branding är i dag ett begrepp som är välkänt bland marknadsförare. Fördelarna med en unik och genomarbetad ljudidentitet har dock inte nått fram till många svenska företag och varumärken. Vi ämnar med detta kandidatarbete att utforska ljudets funktion för varumärkesbyggande samt skapa förståelse för vilka faktorer som är avgörande gällande ljuddesignen i reklamsammanhang. Genom tidigare forskning samt produktion av sonic logos och musik, åt olika beställare, har vi försökt besvara frågeställningen: Hur ger man verksamheter och varumärken en ljudidentitet? Abstract Sound branding today, is a well-known concept amongst marketers.

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

This Masters thesis is a study of the truck-driver profession and their use of libraries located in gas-stations and restaurants along the highways in Sweden. The reason for this interest is the positive trend that has occurred concerning men without any university education and their reading-habits, that is due to their increased interest in listening to audio books. This challenges the general opinion that this group is not particularly interested in reading literature. Questions posed in this study are: How do the truck-drivers relate to the activity of reading literature, what part does the road-libraries play, and how can the services that the road-libraries offer be improved according to the truck-drivers. The method used in the study is interviews made by telephone.

Dagens digitala spel är oerhört komplexa produktioner som ofta kräver en multitud av  sofistikerade verktyg för att förverkligas. Ett intrikat nätverk av moderna lösningar där såväl  visuella som audiovisuella element samverkar för att frambringa fängslande och entusiasmerande  upplevelser är vad som gör dagens spelproduktioner, och ingen annan bransch har sett samma  raketutveckling som spelbranschen sedan dess begynnelse. Ljuddesignens roll i digitala spel har  dock förblivit passiv där andra element tagit an mer dynamiska roller i varierande form.  Generellt sett är ljudet oftast mer ett komplement till de visuella elementen än ett fristående  förmedlingsredskap. Då audiovisuell kommunikation ej delar vissa av de begränsningar som  visuell kommunikation innehar, såsom grafisk processeringskraft, bildskärmsavgränsningar etc,  så ser vi att ljuddesign besitter en stor mängd outnyttjad potential som i teorin hade kunnat  förgylla spelupplevelser kolossalt.Det här arbetet undersöker både genom analoga och digitala medel hur införandet av binaural  lyssning i spelproduktioner kan förbättra navigationsförutsättningarna för användaren avsevärt  då djup och höjd kan skildras mycket mer effektivt, samt hur dess applicering i tredimensionella  miljöer kan främja såväl nöjes­ som lärosyften i så kallade Audio based Environment Simulators  (AbES).

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.

This study deals with work environment from a legal perspective. The study includes legislative history, legislation today and one empirical study. The legislation that concerns work environment (health and safety) in Sweden today is found in the Swedish Work Environment Act (WEA), the Work Environment Ordinance (WEO), Provisions issued by the Work Environment Authority, related legislations and also collective agreements. The WEA, passed by the parliament in 1977, came into force on the 1st of July 1978 and it defines the framework for Provisions issued by the Work Environment Authority, which is an authority superintended by the Swedish government. These Provisions contain more detailed stipulations and obligations with reference to the working environment.

Syftet med detta examensarbete var att underso?ka MEMS och elektretmikrofoner fo?r att finna vilken typ som la?mpar sig ba?st fo?r fo?retaget Comfort Audio AB och deras ho?rselhja?lpmedelsprodukter. Uto?ver detta underso?ktes mo?jligheter att kontrollera upptagningskarakteristik med hja?lp av en teknik vid namn end-fire.Resultaten har erha?llits genom att underso?ka ett antal elektroakustiska egenskaper hos olika mikrofoner, som sedan har ja?mfo?rts med respektive tillverkares tekniska specifikationer. Upptagningskarakteristiken har underso?kts genom konstruktion av en mikrofonuppsa?ttning da?r den summerade signalen underso?kts.
