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 ...
The Effect of Functional Hearing Loss and Age on Long- and Short-term Visuospatial 1 Memory: Evidence from the UK Biobank Resource
(2014)
The UK Biobank offers cross-sectional epidemiological data collected on >500,000
individuals in the UK between 40 and 70 years of age. Using the UK Biobank data, the aim
of this study was to investigate the effects of ...
On the relationship between functional hearing and depression
(International Journal of Audiology, 2015-06)
Objective: To establish the effect of self-rated and measured functional hearing on depression, taking age and gender into account. Additionally, the study investigates if hearing aid usage mitigates the effect, and if ...
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 ...
