Detta arbete handlar om noise och hur det påverkar människans arbetsminne. Den litterära bakgrunden presenterar vad noise är, hur noise fungerar som musik samt en generell överblick över minne och arbetsminnet. Problemet som undersöktes var om noise kunde påverka förmågan att tillgodogöra sig visuell information mer än vad vitt brus gjorde. För att få ett svar på frågan skapades två versioner av ett enkelt spelmoment där testpersonerna, indelade i två grupper, fick se en siffersekvens som sedan skulle skrivas ner. Samtidigt spelades i spelmomentet antingen noise eller vitt brus upp.

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.

According to the National Agency for Education 06-06-2010 are approximately 115 000 students graduating from Secondary School in the year of 2010.Out of these students, we know that thousands of them are hampered by reading and writing disabilities in various degrees. Have these students been given the best support needed when it comes to writing and reading?Compensation may be perceived as a goal for the pupil to catch up with the rest of the educational group or as a vehicle to go round the difficulties. In Sweden, diagnosed dyslexics are not allowed to use speech synthesis, a compensatory technical aid, during the 9th degree national tests.This study?s purpose is to discover if the usage of speech synthesis during the national test of Swedish and reading comprehension might work as a motivation booster for the students and consequently increase their test scores.This is a quantitative study including study including 15 pupils with diagnosed reading and writing disabilities.

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

Velopharyngeal insufficiency may affect resonance, articulation and thus how speech is perceived by other listeners. Velopharyngeal insufficiency is frequently found in the cleft palate population due to structural abnormalities of the palate. The pharyngeal flap is the most commonly used operation designed to improve velopharyngeal function. The aim of the present study was to compare speech before and after pharyngeal flap surgery by perceptual evaluation regarding nasality, articulation and deviant speech. The study includes preoperative and postoperative speech samples of 28 patients who underwent pharyngeal flap surgery at the University Hospital in Linköping between 2002 and 2007.

The purpose of this study was to investigate how young adults withunilateral cleft lip and palate assess their own speech and communication,and to let speech and language pathologists make a perceptual analysis ofthese individuals? speech at the age of 19 years. An additional aim was toexamine the relationship between these two different ways of evaluation.Data was collected through perceptual analysis from audio recordings and byusing a self-report questionnaire based on the ICF-structure (InternationalClassification of Function, disability and health). Altogether, 33 peopleparticipated. One third of the participants had no speech deficiencies.

In this study the speech of adolescents with unilateral cleft lip andpalate (UCLP) and delayed closure of the hard palate was evaluated.Evaluations were made with experienced speech-language pathologists(SLP:s) and lay listeners. The SLP evaluation consisted of typical cleft palatespeech variables and some of them were adapted for lay listeners. Attitudestowards the speech of the adolescents were investigated by asking laylisteners if the speech constituted any hindrance to vocational performance.The SLP:s mainly found nasal escape and velopharyngeal impairment (VPI),although to a small degree and extent. The lay listeners mainly foundresonance deviations and indistinct speech. The latter was associated withhindrance to vocational performance.

Noise music is created around sounds not often welcome in a musical context. Since the birth of electronic music in the 1950s a new perspective on composing has emerged. In electronic music, sounds and their timbre are as much important as melody, harmony and rhythm. This composing perspective is not often observed. Therefore I have examined a musical genre that stretches the boundaries of what we consider music, sound, noise, beautiful and terrible.

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Speech anomalies have been described as characteristic symptoms forthe 22q11 deletion syndrome. However, research on speech and voice in adultswith the syndrome is still scarce. Previous research has indicated that speech andvoice anomalies seen in children with the syndrome might have neurologicalcauses. The aim of this study is to investigate speech and voice in a group ofadults diagnosed with the 22q11 deletion syndrome, with extra focus onanomalies with possible neurological cause. The researched group consisted of24 adults between the ages 19 to 38 with a verified 22q11-deletion, 16 womenand 8 men.
