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 ...
Impact of the presence of auditory neuropathy spectrum disorder (ANSD) on outcomes of children at three years of age
(2013)
Objective—To determine the influence of the presence of auditory neuropathy spectrum disorder
(ANSD) on speech, language, and psycho-social development of children at three years of age.
Deconvolution of overlapping cortical auditory evoked potentials recorded using short stimulus onset-asynchrony ranges
(Clinical Neurosphysiology, 2014)
The first aim of this study is to validate the theoretical framework of Least-Squares (LS) deconvolution on experimental data. The second is to investigate the waveform morphology of the cortical auditory evoked potential ...
Prescribing Amplification for Children: Adult-Equivalent Hearing Loss, Real-Ear Aided Gain, and NAL-NL1
(Sage Publications, 2003-03)
This paper focuses on how the acoustical differences between the ear canals of adults and children affect amplification requirements and describes efficient strategies to allow for these differences when prescribing and ...
Allowing for Asymmetric Distributions When Comparing Auditory Processing Test Percentage Scores with Normative Data
(Journal of the American Academy of Audiology, 2014)
Background: Raw percentage scores can be transformed to age-specific Z scores, despite the asymmetric
distribution of normative data using a process that is applicable to any percentage (or proportion)-
based result.
Purpose: ...
Effect of audibility on spatial release from speech-on-speech masking
(Journal of the Acoustical Society of America, 2015)
This study investigated to what extent spatial release from masking (SRM) deficits in hearingimpaired
adults may be related to reduced audibility of the test stimuli. Sixteen adults with sensorineural
hearing loss and ...
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 ...
The Dichotic Digits difference Test (DDdT): Development, Normative Data and Test-Retest Reliability Studies
(2014)
Background: The dichotic digits test is one of the most widely used assessment tools for central auditory processing disorder (CAPD). However, questions remain concerning the impact of cognitive factors on test results.
Purpose: ...
