1. Signal processing approaches on otoacoustic emissions
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

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

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

4. Hearing Screening of Infants and The Importance of 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.

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