Gut Bacteria Linked to Advanced Language Skills
The University of Alberta-led (U of A)research followed more than 400 infants from the CHILD Cohort Study (CHILD) at its Edmonton site. Boys with a gut bacterial composition that was high in the bacteria Bacteroidetes at one year of age were found to have more advanced cognition and language skills one year later. The finding was specific to male children. An article detailing the research appears on the University's website.

PSAPs, OTC and Self-fitting Hearing Aids, ACHIEVE, and More: An Interview with Nicholas Reed, PhD
Nicholas Reed, PhD, and his colleagues at Johns Hopkins have been involved in some extremely exciting research on personal sound amplification products (PSAPs) and over-the-counter (OTC) devices, as well as cognition and hearing loss. Douglas Beck, AuD, interviews Dr Reed about these topics, as well as the group's recent work on the ACHIEVE study.
63rd International EUHA Congress to Take Place October 17-19, 2018 in Hannover

Introduction to Special Edition on Audiology & Neuroscience
Listening can be thought of as applying meaning to sound, allowing the brain to organize, establish vocabulary, develop receptive and expressive language, learn, and internalize—indeed, listening is where hearing meets brain. Thus, it stands to reason that we, as hearing care professionals, need to become more knowledgeable about the neuroscience of audition.

Real-ear, Cognition, Speech-in-Noise, and More: An Interview with Todd Ricketts, PhD
This month, Dr Beck interviews Todd Ricketts, PhD, of Vanderbilt University about a wide range of topics including how many people are actually purchasing hearing aids each year, what we can and cannot say about hearing loss and dementia, the effective hearing range of humans, RECD and speech in noise measures, and more.

Back to Basics: Hearing Aids and the 3 PM Crash
Since the beginning of my audiology career I have heard many of my hard-of-hearing patients comment that at around 3 PM they hit the wall and need a nap.

Compression Speed and Cognition: A Variable Speed Compressor for All
In the past 15 years, research has suggested that people with hearing loss might benefit from either fast or slow compression depending on their cognitive status. This article reviews the concept of compressor speed and its possible relationship to cognitive capacity and also looks at how the Variable Speed Compressor (VSC) used in the BEYOND hearing aid may allow optimal speech understanding for people with all cognitive backgrounds.

Diagnosis of Dementia Affected by Hearing Loss
New research shows that reduced audibility significantly reduces scores on the MMSE—the most popular tool for physicians and psychiatrists for assessing cognitive status—resulting in greater apparent cognitive deficits and possible misdiagnosis of dementia.

Undiagnosed Hearing Loss in Seniors Means More Isolation, Study Finds
A new study finds that for every 10 decibel drop in hearing sensitivity, the odds of social isolation increase by 52%. A survey sample of seniors also revealed that a 10 dB reduction in hearing was associated with cognitive declines equivalent to almost 4 years of aging.

Listening to Language Boosts Infant Cognition
Northwestern University researchers have found that even before infants understand their first words, they have begun to link language and thought. Listening to language boosts infant cognition, and new evidence provides insight into the role of early language exposure.

Research Suggests Enhanced Auditory and Cognitive Skills for Meditators
Meditation has been shown to cause physiological and neurological changes, enhancing a range of cognitive processes and self-regulation abilities, including temporal resolution ability, speech perception in noise, cognition, and auditory processing.

Issues in Cognitive Screenings by Audiologists
The discovery and management of cognitive issues, which may masquerade as or occur in tandem with hearing problems, allows the hearing healthcare professional to better address the global needs of the patient in a timely manner. In this article, Douglas Beck, Barbara Weinstein, and Michael Harvey advocate for the universal cognitive screening of patients aged 70 and older with hearing loss, even in the absence of obvious signs or symptoms of cognitive impairment.

Cognitive Research on Hearing: Toward Implementation in Hearing Instruments
This paper describes two aspects of hearing instrument signal processing that are important for providing the most advantageous auditory input to the individual, when higher processing and cognition are considered.

Beyond Audibility: The Role of Supra-threshold Auditory Processing and Cognition in Presbycusis
Studies demonstrate that, even in the absence of elevated audiometric thresholds, various levels of speech processing are affected by age and co-occur with changes in cognition and a decline in the sensitivity to supra-threshold temporal cues. Christian Füllgrabe, PhD, says that, from a clinical perspective, this indicates a need for diagnostic tests in addition to the audiogram when assessing the hearing of older people.

Perfect Pitch May be Possible for Adults to Acquire
Researchers at University of Chicago have trained some adults to develop an ear for perfect pitch, which was previously believed to be a special talent that must be nurtured with musical training during childhood. The new study shows that adults with no special musical ability can acquire the skill.
