Subjective preference for a high power hearing aid utilizing a directional microphone

This paper discusses the use of a directional microphone by hearing aid users.

Comparison of a special hearing aid with a conventional aid for detection and discrimination of high-frequency phonemes

This paper is a review of a study to determine if a special hearing aid, the Transposer, can supply high frequency information to profoundly deaf children.

Parental observations of children's responses to three sensory aids: cochlear implant, tactile aid, hearing aid

This study discusses a project undertaken to determine the benefits of sensory aids for hearing impaired children based on parental observations over a twelve month period.

Evaluation of a feedback equalization algorithm in the CID Wearable Digital Hearing Aid

This paper describes the results of an investigation which examined the efficacy of a feedback equalization algorithm incorporated into the Central Institute for the Deaf Wearable Digital Hearing Aid. The study examined whether the feedback equalization would allow for greater usable gains when subjects listened to soft speech signals, and if so, whether or not this would improve speech intelligibility.

A study of hearing aid user satisfaction based on the hearing aid performance inventory

This paper discusses a study to determine the effectiveness of the Hearing Aid Performance Inventory (HAPI) on hearing aid outcomes.

Procedures for selecting hearing aid compression ratios based on individual loudness judgements

This paper examines the selection of compression ratios for hearing aids.

The use of a single channel, two attenuator hearing aid by severely hearing impaired children

This paper examines the results of testing five severely hearing impaired children using a special binaural system with s single amplification channel and two attenuators, allowing presentation of the stimulus materials monaurally or at different relative levels to the two ears.

A hearing aid orientation pamphlet for clinical use with first-time hearing aid users

This paper discusses the use of a pamphlet to help first-time hearing aid users adjust to their hearing aids.

Hearing-aid volume control adjustment by deaf children

This paper examines hearing aid volume control adjustments by deaf children. Specifically the study looks at how accurately deaf children set the volume controls of their hearing aids, if deaf children are able to comprehend the effects of talker-microphone distance on stimulus intensity, and do deaf children use their hearing aids to monitor their own voices.

Preliminary work on development of a new hearing aid booklet for parents of young hearing impaired children

The purpose of this study was to evaluate current materials given to parents of new hearing aid users.

The effect of talker age and gender on speech perception of pediatric hearing aid users

Even though pediatric hearing aid (HA) users listen most often to female talkers, clinically-used speech tests primarily consist of adult male talkers' speech. Potential effects of age and/or gender of the talker on speech perception of pediatric HA users were examined using two speech tests, hVd-vowel identification and CNC word recognition, and using speech materials spoken by four talker types (adult males, adult females, 10-12 year old girls, and 5-7 year old girls). For the nine pediatric HA users tested, word scores for the male talker's speech were higher than those for the female talkers, indicating that talker type can affect word recognition scores and that clinical tests may over-estimate everyday speech communication abilities of pediatric HA users.

Emotion perception and talker discrimination in pediatric hearing aid users

The primary goal of this study is to examine the ability of pediatric hearing-aid listeners, with mild to moderately-severe hearing loss, to perceive emotion and to discriminate talkers. These listeners’ performance is compared to that of similarly-aged listeners with normal hearing and who use cochlear implants.
