Hearing-Aid Safety: A Comparison Of Estimated Threshold Shifts For Gains Recommended By Nal-Nl2 And Dsl M[I/O] Prescriptions For Children, Teresa Y. C. Ching, Earl E. Johnson, Mark Seeto, John H. Macrae
Hearing-Aid Safety: A Comparison Of Estimated Threshold Shifts For Gains Recommended By Nal-Nl2 And Dsl M[I/O] Prescriptions For Children, Teresa Y. C. Ching, Earl E. Johnson, Mark Seeto, John H. Macrae

Objective: To investigate the predicted threshold shift associated with the use of nonlinear hearing aids fitted to the NAL-NL2 or the DSL m[i/o] prescription for children with the same audiograms. For medium and high input levels, we asked: (1) How does predicted asymptotic threshold shifts (ATS) differ according to the choice of prescription? (2) How does predicted ATS vary with hearing level for gains prescribed by the two prescriptions? Design: A mathematical model consisting of the modified power law combined with equations for predicting temporary threshold shift (Macrae, 1994b) was used to predict ATS. Study sample: Predicted threshold shift were …

Objective: To examine the impact of prescription on predicted speech intelligibility and loudness for children. Design: A between-group comparison of speech intelligibility index (SII) and loudness, based on hearing aids fitted according to NAL-NL1, DSL v4.1, or DSL m[i/o] prescriptions. A within-group comparison of gains prescribed by DSL m[i/o] and NAL-NL2 for children in terms of SII and loudness. Study sample: Participants were 200 children, who were randomly assigned to first hearing-aid fitting with either NAL-NL1, DSL v4.1, or DSL m[i/o]. Audiometric data and hearing-aid data at 3 years of age were used. Results: On average, SII calculated on the …

Vestibular-evoked myogenic potentials (VEMPs) supplement the vestibular test battery by providing diagnostic information about otolith organ function. The purpose of this presentation is to provide an update on the clinical use of the cervical VEMP and ocular VEMP as clinical tests of otolith function

A major decision at the time of hearing aid fitting and dispensing is the amount of amplification to provide listeners (both adult and pediatric populations) for the appropriate compensation of sensorineural hearing impairment across a range of frequencies (e.g., 160?10000?Hz) and input levels (e.g., 50?75?dB sound pressure level). This article describes modern prescription theory for hearing aids within the context of a risk versus return trade-off and efficient frontier analyses. The expected return of amplification recommendations (i.e., generic prescriptions such as National Acoustic Laboratories?Non-Linear 2, NAL-NL2, and Desired Sensation Level Multiple Input/Output, DSL m[i/o]) for the Speech Intelligibility Index (SII) …

This presentation summarizes the preparation for, and execution of, audiology series provided by East Tennessee State University's Audiology, Program at Remote Area Medical (RAM) expeditiors in the Southern Appalachian region. In 2010 and 2012, ETSU audiology faculty and students evaluatd 281 patients and subsequently fit 178 hearing aids.

Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection

Excerpt: It is often the case that veterans who experience hyperacusis have hearing loss and tinnitus; what sets the patient with PTSD apart is an increased likelihood that will rate sound tolerance problems as more severe than tinnitus and hearing loss.
