1. 1. Hearing and cognition in speech comprehension. Methods and applications

   Författare :Mathias Hällgren; Stig Arlinger; Birgitta Larsby; Arne Leijon; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; physiology; cognition; cognition disorders; dichotic listening tests; hearing loss; sensorineural; neuropsychological tests; speech perception; Audiology; Audiologi;

   Sammanfattning : Central auditory processing is complex and can not be evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests and cognitive tests that tax functions important for speech processing. LÄS MER

3. 2. Selection of stimuli for listening tests by software-assisted ranking

   Författare :Jonas Ekeroot; Nicholas Zacharov; Luleå tekniska universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Ljudteknik; Audio Technology;

   Sammanfattning : Within the academic field of audio technology, which is the context of this thesis, research questions related to various forms of perceptual audio evaluation of different types of audio systems are important and commonly encountered. Methods for systematic evaluations of listeners’ perceived audio quality, based on different experimental designs, have evolved over a time span of several decades and are collectively referred to as listening tests.

4. 3. Sound Quality of Flue Organ Pipe. An Interdisciplinary Study on the Art of Voicing

   Författare :Vincent Rioux; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; listening tests; psychoacoustics; verbal descriptors; flue organ pipes; musical acoustics; sound quality; deterministic stochastic separation; timbre; time-frequency analysis;

   Sammanfattning : This thesis presents a research study carried out in collaboration with a department of applied acoustics, a department of musical acoustics and an organ workshop. The description of the sound quality of flue organ pipes has received fairly little attention either in organ-building or scientific literature, despite its importance in the overall quality of the instrument, probably due to the difficulties inherent in doing so.

5. 4. On Reverberation Enhancement in Auditoria

   Författare :Peter Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active sound field control; room acoustics; reverberation enhancement; listening tests; subjective effects; sound-reinforcement; feedback systems; feedback control; computer modelling of acoustics in enclosures; modulation; electro acoustics; time-varying filters;

   Sammanfattning : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. LÄS MER

7. 5. Diagnosing colorectal cancer in primary care : the value of symptoms, faecal immunochemical tests, faecal calprotectin and anaemia

   Författare :Cecilia Högberg; Mikael Lilja; Jörgen Månsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; faecal immunochemical tests; faecal calprotectin; anaemia; symptomatic patients; rectal bleeding; primary care;

   Sammanfattning : Background: Colorectal cancer (CRC) is the third most common cancer in men and the second most common in women worldwide. Adenomas can be precursors to CRC, and inflammatory bowel disease (IBD) can present with the same symptoms as CRC. The majority of patients with CRC initially consult primary care. LÄS MER
