The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

NCC has given us a commission to investigate a planned housing area in Haga, Karlstad, situated close to the traffic route Hagaleden and the railway. The housing area consists of one hundred apartments in five different houses. The houses are linked to each other by balconies with glass panels. A long carport is situated between Hagaleden and the housing area to absorb part of the noise from the road. The design of the housing area is creating a silent backyard.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

AbstractArvid Nerdal: Tre svenska gospelkörers sound och uttryckssätt i förhållande till den afro-amerikanska gospeltraditionen. ? Uppsala: Musikvetenskap 2000. 60 p.Uppsatsens syfte är att studera tre utvalda svenska gospelkörer och jämföra deras ?sound? och uttryckssätt med ett urval typiska stilistiska element inom den afro-amerikanska gospelkörgenren.

Detta examensarbete är en förstudie där väl lyssningsanpassade rum har undersökts både objektivt och subjektivt med syftet att kunna identifiera och tolka allmänna akustiska fenomen som uppstår, och upplevs, samt upplysa läsaren om dessa. Rapporten behandlar ljudfysik så som akustik och våglära, ljudteknikerns roll, psykoakustik, kontrollrum och teknisk utrustning. De mätningar och lyssningstest som utförts har alla utgått ifrån den tänka lyssningspositionen som sedan ställts mot specifika krav och rekommendationer från AMS (Audio Measurement Standards) och EBU (European Brodcasting Union). Lyssningstesten har gjorts efter EBU-standard. Även intervjustudier har genomförts med erfarna ljudtekniker.

At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.

I denna uppsats har filmljudet i krigsfilmerna Apocalypse Now och Saving Private Ryan undersökts. Detta har gjorts för att försöka bidra med ökad förståelse för filmljudets användningsområde och funktioner, främst för filmerna i fråga, men även för krigsfilm rent generellt. Filmljud i denna kontext omfattar allt det ljud som finns i film, men utesluter dock all ickediegetisk musik. Båda filmerna har undersökts genom en audio-visuell analys. En sådan analys görs genom att detaljgranska båda filmernas ljud- och bildinnehåll var för sig, för att slutligen undersöka samma filmsekvens som helhet då ljudet och bilden satts ihop igen.

This bachelor´s thesis analyzes the video game Red Dead Redemption and the historical use of the environment and atmosphere in the game. The theory and method used is media research and social memory studies. Two questions were asked: how does Red Dead Redemeption convey and produce the historical environment and the historical atmosphere. Furthermore subqueries/criterias were used to help answer the main questions.The analysis was divided into two parts, the first part we analyze and discuss the games historical environment and the second part analyzes and discusses the historical atmosphere of the game.The conclusion is that both the historical environment and the historical atmosphere is present in the game through picture and sound, the text only works as a guide. The picture and sound live in a symbiotic relationship and depend on each other to fully immerse the player to the game.

Can coercive care be justified against drug and alcohol addicts or should treatment be offered on a strictly voluntary basis? This was one of the central questions debated in Sweden during the 70's when the development of a new social legislation, The Social Services Act (Socialtjänstlagen), took place. The first aim of this thesis was to analyse whether the arguments that were presented both in favour for and against coercion were sound. To achieve this, a method for analysing arguments was employed, where a sound argument is defined as acceptable, relevant and adequate. The analysed material consists of both official government reports and books of influential debaters.

Denna slutreflektion beskriver arbetet med att designa soundtracket till filmen Ont blod, en novellfilm som spelades in på Gotland hösten 2010 av Andersson/Wilén produktion. Vårt arbete har varit postproduktionen av allt ljud, inklusive musikkomponering. Syftet med arbetet var att testa och jämföra de två metoder av surroundmixning (direct/ambient och direct-sound all round) för film som Holman (2008) beskriver, för att sedan välja den som passar vår produktion bäst. Reflektionen är skriven i två delar. Den första delen handlar om produktionen i sin helhet och om projektplanen.

We read different kind of texts every day. We can for example choose to read a book or to watch a film. While we read we can receive and interpret texts. That?s means, for example, that we can have different envisionments about the drama and the film based on it. Based on Langer?s reception theory about ?envisionments?, I?ve wanted to examine and clarify the differences and similarities of envisionments between two texts.

Syfte: Rapportens syfte är att kartlägga om upplevelsen av ett rum kan förändras beroende på om och vilka ljud som spelas upp i rummet. Metod: I samband med en ljudinstallation på Plattan vid Malmö Högskola har rörelsemönster och beteende för Plattans besökare observerats. Dessutom har flera besökare besvarat en enkät. Resultat: Inga eventuella förändringar i rörelsemönstret eller beteendet för Plattans besökare kan ses som en konsekvens av ljudinstallationen. Det finns inte heller någon skillnad i enkätsvaren beroende på installationen. Slutsats: Resultatet ses som en konsekvens av bristfälliga forskningsmetoder. I rapportens slutsats bildas hypotesen att en installerad ljuddesign inte är en tillräcklig åtgärd i den undersökta typen av miljö.

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.
