What factors influence variation in directional microphone benefit?
(2012)
Many studies have demonstrated an average directional microphone (dirmic) benefit of 3-3.5 dB, a value that corresponds well to expectations from physical performance measures of conventional directional instruments. A ...
Perception and management of a self-fitting hearing aid among older adults
(2011)
NAL is currently investigating if a ‘self-fitting hearing aid’ (SFHA),
a device that users can program themselves without the need for
audiological or computer support, is a viable solution for
populations who have ...
The Self-Fitting Hearing Aid
(2010)
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 ...
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)
