EVOKED POTENTIALS

 

Comparison of ABR response amplitude, test time, and estimation of hearing threshold using frequency specific chirp and tone pip stimuli in newborns.
Ferm, I., Lightfoot, G. and Stevens, J. (2013) International Journal of Audiology, 52(6), pages 419-423

A relatively recent innovation in auditory evoked potentials is the narrowband CE-chirp, a sound stimulus designed to improve synchrony of evoked neural activity. This paper describes the key characteristics of ABR amplitude and latency, as well as signal-to-noise ratio for CE-chirp stimuli over a range of frequencies and levels, in comparison to conventional tonepip stimuli in the same group of individuals

Comparing auditory brainstem responses (ABRs) to toneburst and narrow band CE-chirp in young infants.
Rodrigues, GR., Ramos, N. and Lewis DR. (2013) International Journal of Pediatric Otorhinolaryngology, 77(9), pages 1555–1560

A relatively recent innovation in auditory evoked potentials is the narrowband CE-chirp, a sound stimulus designed to improve synchrony of evoked neural activity. This paper describes the key characteristics of ABR amplitude and latency for CE-chirp stimuli over a range of frequencies and levels, in comparison to conventional tonepip stimuli in the same group of individuals.

Automated auditory response detection: Improvement of the statistical test strategy.
Stürzebecher, E. and Cebulla, M. (2013) International Journal of Audiology, 52(12), pages 861-864

Automated electrophysiological response detection is a key component of hearing screening programmes, and relies on balancing the time needed to complete the test, with appropriate statistical robustness in response detection. This article details a test strategy that may improve performance in ASSR detection by decreasing test time and increasing response detection rates.

Predictive value of hearing assessment by the auditory brainstem response following universal newborn hearing screening.
Stevens, J., Boul, A., Lear, S., Parker., G., Ashall-Kelly, K. and Gratton D. (2013) International Journal of Audiology, 52(7), pages 500-506

This longitudinal study compares the accuracy of estimated hearing thresholds in hearing impaired infants using the ABR in the neonatal period, with the behavioural thresholds gathered at a later date when such behavioural testing became feasible. Agreement was around 10 dB for a 4 kHz tone-pip ABR and the corresponding behavioural threshold, and around 17 dB for the 1 kHz comparison.

Effects of Artefact Rejection and Bayesian Weighted Averaging on the Efficiency of Recording the Newborn ABR.
Lightfoot, G. and Stevens, J. (2013) Ear and Hearing, 35(2), pages 213-220

The reality of hearing screening programmes is that recording conditions (noise levels) for measuring auditory evoked potentials can sometimes be less than ideal, and can change within a test session. This paper outlines the optimal settings of two key tools used for maximising the signal-to-noise ratio of auditory evoked potentials in a range of different noise levels.

FITTING

Hearing aids services – needs and technology assessment for developing countries.
World Health Organization (1998)

This document contains proceedings from the WHO workshop, hosted with support from the Christoffel-Blindenmission (CBM) in Bensheim, Germany. The problems and needs for hearing aid provision, and audology training needs amongst of health workers in developing coutries across the six WHO regions were covered, and their conclusions presented.

Guidance on the use of real ear measurement to verify the fitting of digital signal processing hearing aids

This document outlines procedures for verification of the performance of a hearing aid (and ear mould) on a particular patient. Guidance is provided both for typical adults and children, and cases with added complexity such as with severe/profound losses, or those with a conductive component. These guidelines are widely followed in the UK. This and other resources are available for download at http://www.thebsa.org.uk/resources/

The value of routine real ear measurement of the gain of digital hearing aids
Aazh, H. and Moore, B. (2007) Journal of the American Academy of Audiology. 18(8): pages 653-64.

This study aimed to determine the extent to which real-ear measurements are necessary in the fitting process of digital hearing aids, and the extent to which adjustments to the hearing aid settings are required in the verification process. The results showed 83% of aids met the desired performance after real-ear verification, compared with 63% before, supporting the need for these measures for more accurate fittings.

Hearing aid software predictive gain values: How accurate are they?
Hawkins, D. and Cook, J. (2003) The Hearing Journal, 56 (7) pages 26-34

This study aims to document the extent to which a particular hearing device produces the performance to which the manufacturer states. Often the two will differ, for example due to manufacturer tolerances in components of the device, and the acoustical properties of the particular ear. The results showed that actual performance at some frequencies may be over 20 dB different than might be assumed from manufacturer guidelines.

Speech mapping is a valuable tool for fitting and counseling patients.
Moore, B. (2006) The Hearing Journal, 59(8) pages 26, 28, 30

This article outlines some of the limitations in real-ear measurements for verifying the fitting of a hearing aid, and a solution to at least some of these limitations in the form of ‘speech mapping’, i.e. documenting and visualising the audibility of sounds that are realistic to the hearing aid user, such as speech or music.
