Top 5 Articles of 2012!

2012 was an impressive year for scientific publication in audiology research and hearing aids. Narrowing the selection to 15 or 20 articles was much easier than selecting 5 articles from that respectable ensemble. After some thought and discussion with several colleagues, here are the top 5 articles published in 2012!

A quick summary on the benefits of bilateral hearing aid use

Here’s a quick summary on the benefits of bilateral hearing aid use. This is the last in the series on bilateral vs. unilateral hearing aids. The next series will focus on outcome measures, ranging from tried and true with the SSQ to new and spry with the TFI.

Do Patients with Severe Hearing Loss Benefit from Directional Microphones?

This update concludes the series on patient outcomes with severe hearing loss. The reviewed article discusses outcomes with directional microphones as well as the value of audio-visual cues.

Spectral Envelope Warping (SEW): Spectral iQ

AudiologyOnline.com has posted a summary of Spectral iQ. A means for replicated high-frequency speech cues at lower frequencies; a process called spectral envelope warping (SEW).

Spectral iQ

This paper introduces a new method for frequency lowering in hearing aids. Many individuals with high-frequency hearing loss do not have access to the highest frequency components of speech. Technologies such as Spectral iQ are designed to move the highest frequency information to lower frequencies, which for most patients results in increased audibility for those sounds.

Are our fine-tuning adjustments consistent with the patient’s complaints?

In this throwback to 2003 Jenstad and colleagues completed a study that evaluated consistency in interpretation of patient complaints and the actions that would be taken to address these complaints. Their findings show excellent agreement between the interpretation and subsequent actions made by two independent groups of survey respondents.

Recommendations for fitting patients with cochlear dead regions

Clinically many audiologists may struggle with deciding how to best to prescribe hearing aids when a patient has been diagnosed with cochlear dead regions. The September blog update discusses a recent article from Dr. Robyn Cox and colleagues at the University of Memphis. The authors completed a large scale study, evaluating some outcomes for patients who were diagnosed with cochlear dead regions. Their conclusions offer direction for the fitting of hearing aids.

A preferred speech stimulus for testing hearing aids

Do you use a speech stimulus when testing hearing aids? With so many options for real-ear measures it’s difficult to select between noise, synthetic speech or real speech. Each of which may yield different measurement results. Ideally we would have a standardized speech stimulus for testing hearing aids. This month’s post summarizes the development of the International Speech Test Signal (ISTS) a speech stimulus designed for testing hearing aids. Within a few years this stimulus should be available in most real-ear equipment and can currently be regarded as the preferred stimulus for the verification of modern hearing aids.

Awash in a stream of wireless solutions

This month’s issue of Audiology Practices includes an article that discusses methods for streaming audio (television and telephone) to modern hearing aids. With multiple options for wireless communication with hearing aids selecting among these technologies can feel daunting.
