Factors influencing individual variation in perceptual directional microphone benefit
(Journal of the American Academy of Audiology, 2013-02)
Background: Large variations in perceptual directional microphone benefit, which far exceed the variation expected from physical performance measures of directional microphones, have been reported in the literature. The ...
NAL-NL2 empirical adjustments
(Trends Amplification, 2012)
NAL-NL1, the first procedure from the National Acoustic Laboratories (NAL) for prescribing non-linear gain, was a purely theoretically-derived formula aimed at maximizing speech intelligibility for any input level of speech ...
Identification of Conductive Hearing Loss Using Air Conduction Tests Alone: Reliability and Validity of an Automatic Test Battery
(Lippincott Williams & Wilkins., 2014-01)
The primary objective of this study was to determine whether
a combination of automatically administered pure-tone audiometry and
a tone-in-noise detection task, both delivered via an air conduction (AC)
pathway, could ...
Client-Based Adjustments of Hearing Aid Gain: The Effect of Different Control Configurations
(Lippincott Williams & Wilkins •, 2008)
Objectives: Facilitating the fine-tuning of advanced
hearing aids requires information about the acoustic
environment. The concept of a “trainable” hearing
aid may provide a more direct approach to
hearing aid fine-tuning ...
Effect of low-frequency gain and venting effects on the benefit derived from directionality and noise reduction in hearing aids
(International Journal of Audiology, 2007-11)
AI-DI = articulation index weighted directivity index, ANOVA = analysis of variance, BKB = Bamford-Kowal-Bench sentences, BTE = Behind-the-ear, CD = Compact Disc, DI = directivity index, famplified = frequency at which the ...
Validity and reliability of in-situ air conduction thresholds measured through hearing aids coupled to closed and open instant-fit tips.
(International Journal of Audiology, 2010)
An algorithm that administer adaptive speech-in-noise testing to a specified reliability at 1 selectable points on the psychometric function
(The International Journal of Audiology, 2012)
The NAL-NL2 prescription procedure
(Audiology Research, 2011)
