The public interest in central living in today?s cities has led to an increasing effect of traffic noise pollution, and today 20% of the inhabitants in Sweden suffer from noise a level that exceeds the limits. At the same time the traffic keeps increasing, and recent researches shows that traffic noise pollution and several of today?s most common health issues are connected, for example, reduction of performance, sleeping issues and cardiovascular diseases. For this cause rules, guidelines and environmental goals has been developed, as well as software?s which calculates the levels of pollution, all this to investigate and improve the environment.

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.

Nature´s healing capacity is well known and is today an important asset in the protection against stress. Noise problems in cities and it´s green spaces are increasing which in turn provokes stress and in the long term can lead to cardiovascular diseases. To promote people?s health it is important that natural environments have good soundscapes, research show that visiting natural surroundings and listening to sounds of nature promote rehabilitation and relief stress. The purpose of this essay is to determine the value of rehabilitation in forests in Carlshem and Röbäck.

The purpose of this project was to find out how reading is affected, and not affected, by different elements on a start page. The site I was studied belongs to the magazine Fitness Magazine, and the current site has a problem. The editorial texts and articles don?t reach out to the visitors. The goal was to make a proposal for a new first page of the web site that highlights the texts and the reading.With the help of interviews, user testing and textual analysis, I studied if the texts were in itself that caused the problem or if it was the design.

In our everyday life we are constantly affected by sound; at home, on our way to and from work, when taking a walk through the woods and when we sleep. In discussions about sound one often talk about noise and to what degree a certain noise disturbs us. The positive qualities of a sound and what sounds contribute to the experience of a good environment is rarely discussed. The question of sound and the quality of sound is given more attention through the expansion of Stockholm, the city is becoming both bigger and more crowded. This raises new questions concerning the planning of the city e.g. should the changes of the sound quality in a place be one of the aspects taken into consideration when planning new buildings, are there ways to improve the sound quality in new building projects? Can we even improve the quality of sound in existing places by simple means? I have chosen to study four different areas in Stockholm; Hötorget, Mariatorget, Berzeliipark and Norrmalmstorg.

This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.

In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..

Purpose: To examine the hearing environment for tattoo artists regarding occupational noiseand to see whether tattoo artists are exposed to hazardous noise according to Swedish WorkEnvironment Authority regulations. Method: Using a dosimeter we measured a total ofseven sessions of approximately one hour on seven different subjects, located on five studiosin Gothenburg. As a complement we did also hand out surveys based on twelve questions toexamine habits, experienced sound environment and to see if there were any hearing relatedpatterns. Results:. Sound level measurements showed that the lower exposure action valueLpAeq,8h 80 dB(A) in one case was reached if applied to the average working time of sixhours.

The hospital in Varberg has a somewhat outmoded solution regarding the state of preparedness in its water sustentation. Today?s solution is both cause to a number of mishaps and high energy consumption.The report is initiated by looking into the present situation to get an insight to the problem.Today?s media depletion is measured and analyzed.Furthermore, it also looks into some earlier performed studies. These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..

An open fitting is suitable for persons with sloping hearing loss and relatively good low fre-quency hearing. Sensory neural hearing losses often have this type of configuration. A large ventilation canal gives a greater feeling of comfort and less occlusion. The purpose of this study was to look at the hearing aid benefit of open fitted hearing aids. Self report question-naires were sent out to 102 patients who were given ReSound AIR during the year of 2006 in Uddevalla.

Syftet med litteraturstudien var att undersöka hur buller påverkar sjukhusmiljön med hänseende på vårdpersonal och patienter. Studiens avsikt omfattar även en undersökning av vårdpersonalens och patienters eventuella olika uppfattningar angående buller. Effekterna av buller och dess omfattning inom vårdavdelningsmiljön har också undersökts. Resultatet av studien visar på att bullermiljön på sjukhus överskrider de riktlinjer för buller som WHO fastslagit. Vidare visar studien på indikationer på att brittiska sjuksköterskors kunskap angående fenomenet buller är bristfällig.

Manne Bouveng, CEO of Optimel AB had an idea for a new kind of storage cabinet that could be adapted especially for townhouse owners. I came in contact with Manne by a familiar friend for us; we met and decided that it would suit as my thesis.What was needed to be done was a market research that would possibly show that there was a need for a new kind of storage cabinet on the market. Because of this we continued to work on the basic idea. We came up with a solution where we developed a box that resembles Optimels known mailbox Biggi Rondo, the storage cabinet is a new solution of a storage cabinet, adapted after a market that need of a lot of new space. The solution is based on a simple construction which sits an inside hang-off device which can attach tool hooks, tool holders and shelves and so on.The purpose of the assignment was to develop a new type of storage cabinet with some kind of solution to attach tools and other garden related stuff. With this we have succeeded and the concept meets the requirements we set ourselves at the beginning of the project..

During pre-slaughter handling of pigs the animals are often subjected to methods that induces stress and are a threat to the wellbeing of the animals, such as mixing of groups, loud noise and transportation. A new law will be implemented in 2006 in Sweden that prohibits mechanical noise exceeding 65 dB in abattoirs. The purpose of the research presented in this paper was to examine the effects of noise and transportation on pig behaviour. The activity and aggressiveness of the pigs were examined with behavioural studies during transportation and during three different noise levels: 55, 75 and 95 dB. Before the noise treatments took place the groups were mixed and half of them were transported for approximately 2 hours. In the study 432 pigs were used.
