Categories of Auditory Performance (CAP) describes a scale used to rate outcomes from paediatric cochlear implantation in everyday life. It differs from more technical measures by being readily applied and easily understood by non-specialist professionals and by parents. Being based on subjective assessments, there is a need to establish whether ratings by(More)
OBJECTIVES To report population-based prevalence of hearing impairment based on speech recognition in noise testing in a large and inclusive sample of U.K. adults aged 40 to 69 years. The present study is the first to report such data. Prevalence of tinnitus and use of hearing aids is also reported. DESIGN The research was conducted using the UK Biobank(More)
OBJECTIVE Cochlear implants for children are known to have impact on the lives of recipients and their families in a variety of ways. To obtain a clearer picture of these benefits, we explored the quality of life of 36 Finnish children and their families 2-3 years after unilateral cochlear implantation. METHODS The studied children were, on average 5(More)
The advent of bilateral cochlear implants (CIs) has increased interest in learning on binaural tasks, and studies in normal-hearing listeners provide important background information. However, few studies have considered learning with discrimination of interaural time difference (ITD). Here, learning with ITD was explored using stimuli that are more(More)
International standards define normal hearing threshold levels (HTLs) and many studies describe speech recognition in noise (SRN) for adults. Less has been published on these characteristics for children. This study aims to establish ranges of HTLs and SRN for otologically normal 7-year-olds. Air conduction HTLs were measured in 189 7-year-olds within an(More)
Maximum length sequences (MLS) have been used to improve the signal-to-noise ratio (SNR) of otoacoustic emissions [Thornton, J. Acoust. Soc. Am. 94, 132-136 (1993)] and the auditory brainstem response [Thornton and Slaven, Br. J. Audiol. 27, 205-210 (1993)]. By implication, a shorter recording time would be required to give equal signal-to-noise ratio(More)
OBJECTIVE Population ascertainment of children having bilateral moderate to profound hearing impairment was undertaken to find out how many had passed (false negatives) and how many had failed (true negatives) a neonatal screening test based on transient-evoked otoacoustic emissions (TEOAE). DESIGN Neonatal screening using a purpose-built TEOAE instrument(More)
Categories of Auditory Performance (CAP) is an index consisting of eight performance categories arranged in order of increasing difficulty. It has been used to categorize 53 children who had been deafened below the age of 3. The children were assessed by means of the CAP before implantation, and over the following 3 years. Before implantation, only 2 of the(More)
BACKGROUND Preverbal vocal and auditory skills are essential precursors of spoken language development and they have been shown previously to predict later speech perception and production outcomes in young implanted deaf children. OBJECTIVES To assess the effect of age at implantation on the development of vocal and auditory preverbal skills in implanted(More)
