“…This was obtained from a sample of 703 children; again, this represents one of the largest normative studies published to date. Previous work on eight normally hearing adults by Ousey et al (1989) revealed a mean WRT of 18.6 dB (A). This suggests that the WRT of 5-year old children will improve by a further 5 dB as they reach adulthood.…”

“…The study used an automated version of the McCormick toy discrimination test known as the Institute of Hearing Research (IHR)-McCormick automated toy discrimination test (ATT) ( Ousey et al, 1989 ; Palmer et al, 1991 ; Summerfield et al, 1994 ). The ATT measures the minimum sound level at which a child can identify words presented in quiet in the sound field.…”

The aims were to: (1) provide word recognition thresholds (WRTs) at 31, 43, and 61 months of age; (2) investigate developmental changes over time; (3) investigate the relationship between OME and WRT, and (4) investigate the relationship between WRT and hearing thresholds. Around 1000 children were tested longitudinally as part of the ALSPAC study, using an adaptive measure of word recognition in quiet. Mean WRTs were 28, 23, and 23 dB (A) at 31, 43, and 61 months, respectively. Normal auditory development is associated with a mean improvement in WRT of 5 dB between age 31 and 61 months. There was a mean increase in WRT of 5 dB and 15 dB when OME was present in one and two ears, respectively. Thus, both unilateral and bilateral OME results in a detrimental effect on hearing ability for speech. Additionally, early and ‘persistent’ OME is associated with greater disability. However by 61 months, previous OME status was not significant. To our knowledge, this is the largest longitudinal study reporting WRT in preschool children with different middle ear status.

“…Aided sound field threshold measurements were undertaken when using warble tone stimuli with the ESPrit 22 worn on optimum sensitivity setting for 0.5 to 4 kHz using the Institute of Hearing Research (IHR)/McCormick Automated Toy Discrimination Test warble tone facility (10). The warble generator provides sound field warble tones at 7 frequencies from 0.25 to 5 kHz at levels from 0 to 78 dB(A) in steps down to 1 dB.…”

“…As such, picture-identi cation tests have mostly been used (e.g. In England, an automated toy-identi cation speech test has been developed (Ousey et al, 1989) and a Dutch version is available (Crul et al, 1994). When the child recognizes the presented word, he or she has to point to the appropriate picture.…”

Paper presented at the 3rd International Congress of Paediatric Audiology, 9-12 May 2000, Copenhagen. During recent years, signi cant progress has been made in the development of methods for screening hearing sensitivity in toddlers. Nowadays, in several countries, nationwide screening programmes are carried out. Much less attention has been paid to the next step, namely treatment of very young hearing-impaired children with hearing devices. A review of published data indicate that the DSL (Desired Sensation Level) hearing aid prescription method, developed especially for young children, is at least a good point to begin hearing aid tting. DSL target values for gain and output seems to be adequate for young children. Documenting the bene t for hearing aid use in young children is still cumbersome. One option is to measure the development of basal auditory functions. A review of available data showed that for this purpose, speech material can only be used in children of 3 years and older. For children of 1 year and older, tests with environmental sounds can be applied. It is concluded that, although growing, there is a lack of tests and limited knowledge on how to optimize hearing aid ttings and how to document hearing aid bene t in toddlers.
