Barn och buller : Hur barn och verksamhet på förskolan påverkas av en hög ljudnivå
There are a lot of different sounds in our sound saturated time. Noise is an unwishable soundand a high sound level can give short- or lingering problems for both children and adults.The purpose was to find out if and in that case why children and the activity at the pre-schoolaffects by a high soundlevel. Another purpose was to examine what the effects would be if thepedagogues set about the work to get a good sound environment at pre-school.The investigation was accomplished in shape of qualitative interwievs where six pedagoguesfrom different pre-schools answered questions about a high soundlevel.All of them have been educated to hearing pilotes.The result of this investigation shows that some pre-schools have a high sound levels but notall of them. In those cases where there is a high soundlevel are there often too many childrenat the same place on the same time. That makes the soundlevel even higher and both childrenand adults are getting tired.By improving the sound environment at the pre-school both children and adults often gets abetter activity.Keywords: high soundlevel, hearingpilot, noise, affects on children..
Ljud eller oljud? : planering av goda ljudmiljöer
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.
Gränsöverskridande Ljuddesign
Transcending sound design is possible. There are unseen possibilities and a
great potential for
improvement and development in sound and music design ? but
there is a great difficulty
penetrating the obstacles that lies in the way for such development to take
place and to exist. The
difficulties in being negotiable and productive lies more within the limits of
the audience it has to
gain, than in itself. It is as though music and sound design has to evolve very
slowly, in an almost
evolutionary style; one step at a time, to be accepted.
En familjs upplevelser av ljud - en pilotstudie
Sound surrounds us in a great extent, we all have experiences of sound and this phenomena has a great meaning in our lives. High levels of sound might be harmful for your hearing and might also cause related difficulties such as tinnitus and sensitivity to sound. Studies reveal a connection between the attitudes toward high levels of sound and the risk behaviours in these situations. The purpose of this study was to explore the experiences and meaning of sound and whether the attitudes toward sound will reflect in a family consisting parents and adolescents. A family consisting two parents and two adolescents participated each and one of them in an interview in this qualitative study that has been carried out of a phenomenological approach.
Riskerar tatuerare hörselnedsättning i arbetet?
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.
Att höra genre : Vad ljudet i filmens inledning berättar om genre
This study deals with a research on what the opening sounds in movies tell us about the story that we are about to follow. The purpose is to examine if and how the sound in the first five minutes of the movie contribute in giving information about the film?s genre. The theoretical base includes both genre theory and Michel Chion?s theory on film sound.
Tidspress och ekonomiskt risktagande
Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and losses.
Ljud i landskapsarkitektur : från buller till kvalitet
Landscape architects has many ways of transforming our cities and landscapes. Traditionally, most attention has been put to visual qualities. Pen and paper are well established as the way to present proposals and to analyse in the landscape architects profession and training.
But are we perhaps missing out on other ways of seeing the landscape?
The purpose of this paper is to present sound as a tool of transformation. Sound in public spaces has long been treated just as noise and therefore unwanted.
INVOXICATED. En interaktiv lek med ljud
Invoxicated is an interactive play sculpture where children can explore the wonderful and playful opportunities of sound. Talk into one end of the sculpture, and the sound will travel through the sculpture and come out in the other end. On its way, the sound gets distorted by a number of sound effects. By bending the sculpture?s body, and pressing the sculpture?s buttons, the sound effects gets altered in real time.

Ett Film som projekt, en film om ljud, en film om ljudet i film. En film inspelad professionellt med professionella medarbetare. Kandidatarbetet gick ut på både skapa en film inriktad på ljud och skapa ett fungerande filmteam. Arbetet tar upp både det tekniska inom filmljud men även processen i ett filmteam. I arbetet följer vi processen från dess början till dess slut.
Hur kan vi utveckla vårt personliga uttryckssätt med ljud?
This is a bachelor thesis that studies and discuss the question: How can we develop our individual narrative technique with sound design in a Swedish drama production? We have done research and empirical studies. We have analyzed movies to get an idea how we use the sound design in Swedish drama productions today. We have produced a movie that gives sound the biggest part. Key words: Swedish drama production, narrative technique, sound design.
En utvärdering av Audiolet för portandet avett röst-drivet program till webben
We where asked to write a webapplication, with similar functionalityas an existing desktop application. The application can todayrecord sounds from a person, mix it together at the optimal place withanother, similar sound and play back the result.The application used mathematical calculation that the developerswhere not familiar with, therefore it was decided to focus on the partsthat involved recording and playing sound, to pave the way for anyfuture implementation.The follwing prototypes where implemneted:1. Read a sound clip from a file.2. Splicing of two sound clips at different points in the clips.3. Generate the sound of a guitar.The result of this evaluation is that web browsers today are notready for this type of application, but that there is potetial as soonas W3C have standardised the use of a microphone as a source to theexisting DSP functions..

Att spela in tramp i studio: En studie om studioinspelning av fotsteg i snö
The complex sound of someone walking in snow aren't easy to create in a studio. The best way to get the sound is to go out on a surface with real snow and record the footsteps there, but it is a complex procedure to get the right sound on the snow because snow sounds different in various temperature and various kinds of snow. It is important to find the right kind of snow to get the right sound on the foot steps. In a studio, the foley artist can create the sound of footsteps in snow by walking on different kind of material, like potato flour, coarse salt or corn flakes, the question is how realistic this materials sounds and what temperature on the snow they sound like. The results shows that the real snow (warm and cold snow) sounds most realistic and the potato flour sounds like warm and wet snow, the corn flakes some think sounds like cold snowwhile others think that it doesn't sound like snow at all and the coarse salt sounds like snow when it is around -10°C in the air, they all sounds similar in realism compared to each other.
