Effect of amplification bandwidth on speech intelligibility

This paper was a study to examine the effect of bandlimiting on speech intelligibility.

Noise exposure in school-age children

This paper discusses a study to determine the average level of noise exposure for school children on a typical school day.

Changes in distortion-product otoacoustic emissions in chinchilla after intermittent noise exposure

This paper discusses the distortion-product otoacoustic emissions (DPOAE) of chinchillas when exposed to noise.

Enhancing the acquisition of phonemic awareness in hearing impaired students

This paper includes suggestions for enhancing phonemic awareness for hearing impaired children.

Use of the storage oscilloscope to train deaf children to convey meaning in sentences through intonation control

This paper is a review of a study to determine if profoundly deaf adolescents could be trained in intonation control in using a two-channel storage oscilloscope.

The effects of noise exposure on nitric oxide synthase knockout mice

This paper studies the role of nitric oxide (NOS 1, NOS 2, and NOS 3 genes) in the mouse cochlea and in noise-induced hearing loss (NIHL). Mice genetically deficient of the NOS 2 and NOS 3 genes were protected from NIHL, indicating that one or both of these genes may be responsible for producing nitric oxide that damages the inner ear when exposed to harmful levels of noise.

Classroom acoustics: the national acoustic standard

This paper discusses the variables affecting classroom acoustics and a case study examination of some local classrooms. Classrooms were measured against proposed American National Standards Institute (ANSI) standards and treatment options for improving acoustics are suggested.

Differential sensitivity to tonal frequency and to the rate of modulation of broad-band noise by hearing-impaired listeners

This dissertation examined whether a hearing impairment of the auditory end-organ has the same or a differential effect on the place and periodicity processes. Differential sensitivities for four normally hearing listeners and for both ears of five patients with unilateral Meniere’s disease were measured for tonal frequency and rate of sinusoidally amplitude-modulated noise at common frequencies and rates of the stimulus.

A word study unit on Latin and Greek prefixes, roots and derivations

This paper contains an outline of study for hearing impaired children to learn language through the study of Latin and Greek roots, derivatives and prefixes.

Distortion product otoacoustic emissions in the bullfrog

Recovery of distortion product otoacoustic emissions in the bullfrog after noise exposure does not correlate with hair cell damage noted on the amphibian papilla.

Comparing auditory steady-state response and auditory brainstem response in normal hearing adults

This paper compares the auditory steady state response (ASSR) thresholds with the click-evoked and tone burst auditory brainstem response (ABR) thresholds in their ability to predict known behavioral thresholds in normal-hearing adults.

A survey of CTA train noise

This paper discusses a study of CTA commuter trains in Chicago and whether Chicago is in need of regulations of standards for noise emitted by CTA trains.

Evaluating social skills in long term cochlear implant recipients

A longitudinal study observing cochlear implant recipients' social skills using ratings from their parents and the students themselves over time. The study looked at how adolescents using cochlear implants rate their own social skills compared to an age matched normative group of hearing students, and compared these ratings with social skills ratings obtained from their parents. The study also compared social ratings in adolescence to previous ratings of the same children obtained in elementary school.

A consumer survey designed to identify attitudes, knowledge, acceptance, and use of assistive listening devices in public facilities

This paper presents a consumer survey of hearing-impaired persons used to identify their attitudes, knowledge, acceptance, and use of assistive listening devices in public facilities.

Balance function following cochlear implantation

Imbalance is a risk of cochlear implantation. This is particularly important in patients receiving bilateral implants, who are often children. 25 adult and pediatric patients undergoing cochlear implantation were tested pre-operatively and post-operatively using tests of balance function. Results showed moderate losses in some test paradigms following implantation in the patient group as a whole. While changes in balance function due to cochlear implantation are not uncommon, their practical effect on function may be minor.
