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 ...
The effects of adding realism to a conventional speech-in-noise test
(2014)
The speech reception threshold (SRT) is routinely used in
research and in the clinic to assess people’s ability to
understand speech in noise. The overall goal of this work was
to determine whether introducing realistic ...
Towards more cognitively challenging speech tests
(2013)
Speech tests are often poor predictors of the
performance of individual listeners in the real world. This
may be in part because they do not adequately engage
all of the auditory and cognitive processes involved in
real ...
The relationship between functional hearing and verbal reasoning
(Swedish Institute for Disability Research, 2015)
Verbal reasoning is an indicator of the ability to think constructively in everyday life, and relies on both fluid (working memory processing) and crystallised (knowledge-based judgement) skills. Recent data (Rönnberg et ...
An Australian version of the acceptable noise level test and its predictive value for successful hearing-aid use in an older population
(2014)
Objective: The Acceptable Noise Level (ANL), a measure of noise tolerance, has been 2 proposed as a predictor for successful hearing aid use. The aims of this study were to obtain 3 normative data, and to evaluate the ...
The effect of functional hearing and hearing aid usage on verbal reasoning in a large community-dwelling population
(Ear & Hearing, 2015)
Objectives: Verbal reasoning performance is an indicator of the ability to think constructively in everyday life, and relies on both crystallized and fluid intelligence. This study aimed to determine the effect of functional ...
Real-life efficacy and reliability of training a hearing aid
(2013)
We investigated if training of hearing aids result in effective and reliable outcomes. Hearing-2 impaired adults trained the compression characteristic from the NAL-NL2 prescription for 3 three weeks and compared their ...
Cognitive Spare Capacity: Evaluation data and its association with comprehension of dynamic conversations
(Frontiers in Psychology, 2015)
It is well established that communication involves the working memory system, which becomes increasingly engaged in understanding speech as the input signal degrades. The more resources allocated to recovering a degraded ...
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 ...
