The application of the Articulation Index (AI) model to the fitting of linear amplification was evaluated for 12 subjects with sensorineural hearing loss. For all subjects, the relationship between percent-correct scores on a nonsense syllable test and AIs was monotonic, indicating that AI was effective for comparing conditions typical of those…

The study evaluated use of the Modified Power Law to predict permanent threshold shift (PTS) resulting from noise exposure in eight children with severe sensorineural hearing loss attributed to overamplification by hearing aids. The PTS tended to be flat across frequency with its course similar to PTS in persons with normal hearing exposed to…

Information is presented about the auditory development of infants and toddlers with hearing impairments, the goals of amplification, and how amplification is selected and assessed. Practical points to enhance hearing aid use and adjustment are offered. (Author/DB)

The manual describes audiology services offered at the Model Secondary School for the Deaf (MSSD). Components are listed for diagnostic services, instructional services, program development, training, and publications. Testing and reporting procedures for MSSD students are outlined. Testing includes pure-tone air conduction testing, tympanometry,…

Intended for teachers and caregivers of severely handicapped individuals with impaired hearing, the manual provides information about hearing and audiological assessment. Section I presents an overview of the nature of sound and the structure of the ear. Section II describes a number of informal assessment procedures which can be carried out in…

This paper addresses three areas related to amplification for infants and toddlers with hearing impairments: (1) identification issues as they relate to early amplification; (2) selection of amplification; and (3) assessment of aided function. Identification issues discussed include the goal of early identification of hearing loss and the impact…

Variability of aided sound field thresholds (ASFTs) was examined in 30 hearing-impaired children comprising 2 age groups (5-9 and 10-14 years). Findings showed that 2 ASFTs would have to differ by more than 10 decibels across signal test frequencies to attain statistical significance. (Author/DB)

Focuses upon the selection and fitting of hearing aids for young children in Japan. Explains fitting methods and their evaluation. Suggests that although most of the schools for the deaf are making serious efforts to establish binaural fitting and use of residual hearing, lack of professional training hinders those efforts.

Examined the effectiveness of the Aided Articulation Index (AAI) in the evaluation of the fitting of hearing aids, using a sample of hearing-impaired children in a kindergarten and primary school for the deaf in Japan. Found that AAI decreased with hearing threshold level and an AAI of 0.3 is necessary for children to function effectively with…

Gives an overview of the present school system in Japan, focusing on early intervention for hearing impairments, auditory compensation devices, and instruction in auditory training. Suggests that recent developments in hearing aid technology have resulted in substantial improvements in the identification and rehabilitation of hearing-impaired…

Presents an overview of hearing aid fitting procedures and auditory rehabilitation for hearing-impaired children in Japan. Reviews issues of audiological management in Japanese schools and discusses two kinds of simplified auditory tests. Finally, highlights several controversial issues surrounding different perspectives and methods of education…
