2. 1. Signal processing approaches on otoacoustic emissions

   Author : Jun Cheng; Karolinska Institutet; Karolinska Institutet; []
   Keywords : otoacoustic emissions; signal processing; time-frequency representation; cochlea; outer hair cell; neonatal hearing screening; basilar membrane nonlinearity; bounce phenomenon; spectral estimation; interrelations of OAEs;

   Abstract : The recent achievement on the measurement of otoacoustic emissions (OAEs) is based on a novel technical development of digital signal processing. OAEs measured in the external ear canal are normal by-products of the active process in hearing, which was discovered by Kemp (1978). READ MORE

4. 2. On noise and hearing loss : Prevalence and reference data

   Author : Magnus Johansson; Stig Arlinger; Einar Laukli; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; irreversible occupational disease; noise-induced hearing; noise-induced measurements OAE ; spontaneous otoacoustic emissions SOAE ; transient evoked otoacoustic emissions TEOAE ; distortion product otoacoustic emissions DPOAE ; Audiology; Audiologi;

   Abstract : Noise exposure is one of the most prevalent causes of irreversible occupational disease in Sweden and in many other countries. In hearing conservation programs, aimed at preventing noise-induced hearing loss, audiometry is an important instrument to highlight the risks and to assess the effectiveness of the program.

5. 3. Quinine as a model for the study of cochlear hearing loss in humans

   Author : Erik Berninger; Karolinska Institutet; Karolinska Institutet; []
   Keywords : cochlear function; hearing loss; inner ear; otoacoustic emissions; quinine; pharmacokinetics; pharmacodynamics;

   Abstract : Quinine has been used for centuries and is still recommended for the treatment of severe falciparum malaria and non-severe chloroquine-resistant malaria. Among its side effects is the concentration-dependent and reversible cochlear hearing loss. READ MORE

6. 4. Hearing Screening of Infants and The Importance of Early Language Acquisition

   Author : Miriam Magnuson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital hearing impairment. Neonatal hearing screening. Late diagnosis. Parental concern. Otoacoustic emissions. Early language acquisition;

   Abstract : This thesis explores the parental perspective on hearing-screening of children, and the importance of the time of detection of a congenital hearing impairment for the child's development. A qualitative approach based mainly on interviews was employed, and the results were analysed according to three different methods - empirical phenomenology, grounded theory, and case-study.

7. 5. 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
