  2. 1. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

    Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
    Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

    Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

  4. 2. Hearing in increasing age. Epidemiological and psychoacoustic aspects

    Author : Radoslava Jönsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; Aged; 80 and over; Audiometry; Demography; Ear; Epidemiology; Hearing; Presbycusis; Psychoacoustics; Questionnaires; Socioeconomic Factors; Sound Localization;

    Abstract : Presbyacusis, age-related hearing decline, is the most common cause of hearing impairment in the more developed countries. Planning of health services for the hearing impaired requires knowledge of hearing in increasing age and in demographic changes. READ MORE

  5. 3. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

    Author : Konrad Konradsson; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; audiology; Pressure; Audiometry; Cats; Animal; Cochlea; Cochlear aqueduct; Ear; Eustachian tube; Hearing; Otorinolaryngologi; Human; Labyrinth; Otorhinolaryngology; Meniere s disease; audiologi; hörsel- och talorganen;

    Abstract : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. READ MORE

  6. 4. The development of the Situated Phoneme (SiP) test : A Swedish test of phonemic discrimination in noise for adultpeople with hearing loss

    Author : Erik Witte; Elina Mäki-Torkko; Susanne Köbler; Jonas Ekeroot; Karolina Smeds; Thomas Brand; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hearing impairment; speech audiometry; phonemic discrimination; realistic masking noise; critical differences; Swedish;

    Abstract : In the current thesis, a Swedish phoneme-level speech-audiometric test in natural background noise was developed. The test is called the Situated Phoneme (SiP) test. READ MORE

  7. 5. The Balanced Electromagnetic Separation Transducer for Bone Conduction Audiometry and Hearing Rehabilitation

    Author : Karl-Johan Fredén Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention magnet; bone vibrator; demagnetization; bone conduction; balanced electromagnetic separation transducer; magnetically induced torque; image artifact; magnetic resonance imaging;

    Abstract : Hearing via air conduction (AC) and bone conduction (BC) are attributed to bethe natural ways of conducting sound to the cochlea. With AC hearing, air pressurevariations are transmitted to the cochlea via the ear canal, whereas with BChearing, sound vibrations are transmitted through the skull bone to the cochlea. READ MORE
