CILcare Awarded ISO Certification

CILcare, a CRO specialized in hearing disorders, announced that it has been awarded the ISO 9001:2015 certification for its quality management system that includes the conduct of pharmacokinetics, efficacy, tolerance, and ototoxicity studies of drugs, gene and cell therapies, and implantable devices.

Brain Activation During New Word Memorization

Very young children learn words at a tremendous rate. Now researchers at the Center for Mind and Brain at the University of California, Davis, have for the first time seen how specific brain regions activate as two-year-olds remember new words — while the children were sleeping.

ABNN Helps Detection in Sonar Systems

In underwater acoustics, deep learning is gaining traction in improving sonar systems to detect ships and submarines in distress or in restricted waters. However, noise interference from the complex marine environment becomes a challenge when attempting to detect targeted ship-radiated sounds.

Traffic Noise Associated with Heart Failure Risk

Exposure to air pollution and road traffic noise over the course of many years may be associated with an increased risk of developing heart failure, and the correlation appears to be even greater in people who are former smokers or have high blood pressure, according to new research published in the “Journal of the American Heart Association.”

NIOSH Study Tracks Usage of Hearing Protection

Among all workers exposed to noise in 2014, NIOSH researchers found the majority (53%) did not wear hearing protection consistently. Industries with the highest HPD non-use among noise-exposed workers included accommodation and food services (90%), health care and social assistance (83%), and education services (82%). Additionally, some of the industries where noise is a well-recognized hazard, were found to have high prevalences of HPD non-use, including agriculture, forestry, fishing, and hunting (74%), and construction (52%).

Evolution Model of Human Speech Re-examined

Scientists have shown that orangutan call signals believed to be closest to the precursors to human language, travel through forest over long distances without losing their meaning. This throws into question the accepted mathematical model on the evolution of human speech according to researchers from the University of Warwick.

Researchers Map Noise-Induced Hearing Changes

A team led by researchers at the University of Maryland School of Medicine (UMSOM) has published an online interactive atlas representing the changes in the levels of RNA made in the different cell types in ears of mice, after damage due to loud noise. These changes in RNA levels are known as changes in “gene expression.”

Mapping Words to Color

In a new study, researchers at the University of Pennsylvania are developing an algorithm capable of inferring a culture’s communicative needs—the imperative to talk about certain colors—using previously collected data from 130 diverse languages.

Managing Listening Difficulties in Patients with ASD and Normal Hearing Sensitivity

Although auditory issues have been consistently identified among the most common parent-reported sensory issues affecting children with ASD, audiologists rarely evaluate complex listening ability during clinical appointments. The disconnect between patients’ presenting complaints and the conventional test battery may stem from limited knowledge of the listening challenges common to patients with ASD or the range of available management options. This study examines testing in a group of children with ASD and normal hearing sensitivity, and introduces a remediation-driven streamlined assessment as well as a management matrix tailored to each distinct pattern of performance on auditory tests.
