Reception of acoustic speech signals as a function of sensation levels by hearing-impaired children

This paper is a review of a study to determine the sensation level at which the best discrimination and recognition occurs for severely and profoundly deaf children and the effect of distortion (peak clipping) has on the child's ability to recognize speech.

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.

Efficacy of the Speech Intelligibility Index as an intervention tool with pediatric cancer patients

This study evaluates the Speech Intelligibility Index (SII) as a tool to describe hearing loss and predict when hearing aids would be appropriate for pediatric oncology patients who have received or are currently receiving cisplatin. The efficacy of the SII is compared to the Brock grade which is commonly used for patients with ototoxic hearing loss secondary to cisplatin treatment. The SII is a discrete measure that precisely reflects the patient’s functional hearing status and is highly correlated with the need for audiologic intervention.

The effect of nonlinear frequency compression and linear frequency transposition on speech perception in school-aged children

The primary objective of this study is to determine whether nonlinear frequency compression and linear transposition algorithms provide speech perception benefit in school-aged children.

Auditory speech-discrimination as a function of age and type of audiogram

This paper reviews a study to determine if loss of speech discrimination is related to age and patients with audiograms showing steep high-frequency losses.

Re-interpretation of early speech perception test (standard version) in Urdu language

This paper resulted in the Urdu language version of the Early Speech Perception Test(ESP).

Visual speech perception: a comparison between younger and older adults

This paper examines the visual speech processing abilities of older adults and the age-related effects on speechreading abilities.

Speech intelligibility in noise-induced hearing loss: effects of high-frequency compensation

This dissertation examines the frequency response that results in the maximum level of speech intelligibility for persons with noise-induced hearing loss.

Computer assisted instruction for developing speech perception skills in profoundly deaf children

This paper evaluates the usefulness of the "Foundations in Speech Perception" computer program developed by Breakthrough, Inc. in conjunction with Central Institute for the Deaf.

A comparison of physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech to subjective judgments of audibility threshold, MCL and UCL for three normally hearing listeners

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

Effect of amplification bandwidth on intelligibility of several different speech samples for a listener with sensorineural hearing loss

This paper examines the effect of amplification bandwidth on speech intelligibility using multiple speech samples.

The development of the computerized version of the early speech perception test battery

This paper discusses the development of a computerized version of the CID Early Speech Perception Test.

Does systematic instruction in rhythmic movement influence the speech of the deaf

This paper discusses the influence of rhythm in teaching of hearing impaired children.

A technique to train auditory and visual memory for speech patterns in young hearing-impaired children

This paper details a technique for training auditory memory for length of speech sounds in preschool children with a profound hearing loss.
