Advances in Amplification: An Interview with ARC 2019 Chair Todd Ricketts, PhD

Are you making your plans for the AAA 2019 in Columbus, Ohio? If so, you will not want to miss this year’s Academy Research Conference (ARC): Advances in Amplification. This conference takes place on the first day of the AAA Annual Conference,
March 27, 2019.

ARC 2019 Chair Todd Ricketts, PhD, kindly accepted our invitation for an interview about this exciting conference.

FDA Approves Marketing of First Self-Fitting Hearing Aid

The Academy has just become aware of the FDA’s approval of marketing of first self-fitting hearing aid and is identifying any necessary steps to protect the community of consumers who are hard of hearing.

We are closely monitoring and asking our members and the state organizations to be watchful of appropriate process in the distribution. 

As stated by the FDA: “…the device must comply with applicable federal and state laws regarding the sale of hearing aids, including state laws that might require hearing aids….”

Evaluating Rehabilitation Options: Poll Results

In August, we posted an “In the News” article that posed the question “What would/have you done in a situation where a patient has expressed significant functional hearing impairment with normal pure tone thresholds (0-25dBHL)?”  Eighty-eight (88) members responded to the query with the following results below. Please note more than one option could be chosen, hence the percentage total greater than 100%.

Children with ANSD Fitted with Hearing Aids

Intervention for children with auditory neuropathy spectrum disorder (ANSD) represents a significant challenge in pediatric audiology. A critical tool for the fitting of amplification in young pediatric patients, the auditory brainstem response (ABR), is compromised in this population for estimation of behavioral thresholds. Despite compromised ABR responses, cortical auditory evoked potentials (CAEP) can often be recorded from ANSD patients, and there is emerging research in the application of CAEP for estimation of behavioral thresholds in this population (He et al. 2013).

2016 Student Research Forum Winners

On Friday, April 15, 2016, the five recipients of the 2016 Student Research Forum (SRF) Awards gave five outstanding podium presentations. The SRF has been in existence for about a decade, and would not be possible without funding in part by the American Academy of Audiology Foundation (AAAF) and an underwriting grant from Plural Publishing, Inc. Each year, the SRF awardees are selected through a rigorous review process from a competitive pool of exciting student research from across the country.

Amplification: Spectral Resolution, Working Memory, Audibility, and More

Davies-Venn and Souza (2014) report hearing thresholds (in isolation) do not provide enough information to predict an individual’s success with amplification. Spectral resolution, audibility, and working memory appear to be significant factors, too. Previous studies have shown individual differences in susceptibility to distortions secondary to non-linear amplification are likely to impact outcomes. Although a multitude of previous publications have shown compression systems are superior to linear systems when the compression system provides substantial improvements in audibility.

Hybrid Cochlear Implants and Localization

Lammers et al (2014) evaluated 18 subjects who had bilateral low-frequency hearing and were implanted with a hybrid cochlear implant (HCI). The authors note that when traditional cochlear implants (CIs) localize sound they depend on interaural loudness differences (ILDs). The authors queried whether the additional low-frequency acoustic information provided through HCI would provide additional localization cues through interaural timing differences (ITDs).

FM Systems for Veterans with Normal Hearing

Saunders et al (2014) report that in the United States, 1.7 million people report traumatic brain injury (TBI) annually. Falls and motor vehicle accidents are the leading causes of TBI and 75 percent of TBI cases are classified as mild. However, between fiscal years 2009 and 2011, approximately 58,000 service members were diagnosed with TBI.
