Bulleremissioner från vertikalaxlade vindkraftverk

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

Skötsam

The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.

Ljudmiljön i skolan : Om hur lärare kan påverka sin arbetsmiljö

My essay is on the subject of teachers work environment with focus on noise and communication. In the essay questions are raised on how a teacher can influence his or hers noisy work environment. A school is a large work place with many employees and is owned and administered by the county municipality which is an even bigger workplace. How big an acting space does a teacher have in such a large organization?My methods of research on these questions have been to conduct interviews and analyzing documentation from The Swedish Work Environment Authority.

Objektiv utvärdering av hälta under ryttare

Background: The most common reason for veterinary care in horses is lameness. Lameness in riding horses is often difficult to evaluate and in many cases may require riding to come to a diagnosis. Evaluation of lameness has proven to be very subjective and depends on the examiner. There is a need to evaluate ridden horses in an objective way.

Wool loss in sheep

The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

Vi hör inte läraren! ? En enkätundersökning i årskurs sex om upplevd ljudmiljö i skolan

Noise in schools can have negative effect on the teaching environment and speech perception. The national Child Environmental Health Surveys (BMHE) conducted in 2003 and 2011 studied how 12-year olds experience their sound environment in school. Results showed that the number of pupils that experience annoyance from noise increased from 2003 to 2011.Aim: The aim of this study was to study how 12-year olds perceive their sound environment in school.Methodology and material: A quantitative questionnaire survey was conducted in the sixth grade at two schools. The questionnaire used included questions from BMHE and self-produced questions. Sixtynine students answered the questionnaire.Results: Over 50 % of the respondents experience annoyance from noise in school several times a week.

Välbefinnande och Kognitiv Prestation : En experimentell studie om positiv sinnesstämning främjar kreativitet och flexibelt tänkande

The purpose of the study was to investigate, through an experiment, if positive mood promotes creativity and flexible thinking. Participants were a total of 93 college students. The main hypothesis was that subjects induced with positive mood would perform better than subjects induced with negative mood, at a test reflecting creativity. To further explore the implications of priming (subliminal manipulated moods), a neutral control group was included. The cognitive test used in the study was Duncker´s The Candle Problem, a test which aims to get the subjects to apply flexible and creative thinking.

Språkliga förmågor och deras relation till läsförståelse hos barn i 12-årsåldern med lätt till måttlig sensorineural hörselnedsättning - en jämförelsestudie

The aim of this study was to examine language abilities and their correlation to reading comprehension in 12 year old children with mild tomoderate sensorineural hearing impairment. Eight children with mild to moderate hearing impairment were tested in listening comprehension, grammatical comprehension, receptive vocabulary, phonological short termmemory, word finding, semantic relations, reading comprehension, comprehension of written words and decoding of words and non-words. The results were compared to results from a comparison group. The children with hearing impairment had significantly lower results in phonological short term memory and decoding. No significant difference was found between groups in reading comprehension.

Vegetation och ljudmiljö

Landscape architecture is a visual profession, but other senses also affect our interpretation of a place. Sounds can give us a lot of information about an environment, and they are often perceived as positive. Despite this, research about outdoor sounds most often focus on the reduction of unwanted sounds ? noise ? but the absence of noise does not result in a good soundscape. To accomplish this, sounds we appreciate are needed.

Kultur för flera marknadsföring av teater för personer med dövhet eller hörselskada

Today many people with disabilities are excluded from cultural activities. The reason for this is that activities and the environment are not adapted to people with disabilities. The aim of this study is to describe the process to make cultural activities accessible and to describe the importance of good communication between cultural suppliers and their customers. Other questions raised are accessibility to cultural activities for people with hearing disabilities, the activities in the marketing process, the interaction between theatre companies and its audience and if the interaction has contributed to the theatre's future development. Qualitative interviews with staff responsible for integration at seven theatres have been performed.
