How could we improve the comfort and effectiveness of these earplugs? What aspects of the ear canal must be taken into account? To answer these questions, researchers from the École de technologie supérieure (ÉTS University) and the Institut de recherche en santé et sécurité du travail (IRSST) analyzed the varying structure of ear canals to find a correlation between their shapes and the effectiveness of three commonly-used models of earplugs.
The perception of our own voice depends on sound transmission through air (air-conducted) as well as through the skull bone (bone-conducted or BC). The transmission properties of BC speech are, however, not well understood. Now, scientists from Japan Advanced Institute of Science and Technology report their latest findings on BC transmission under the influence of oral cavity sound pressure, which can boost BC-based technology and basic research on hearing loss and speech impairment.
Researchers compared changes in preoperative aided speech recognition with postoperative speech recognition among individuals who received cochlear implants.
In a commentary in Exploration in Medicine, Alzheimer's experts lay out a vision for a worldwide research consortium that can give clinicians -- and patients -- the answers to which speech and language changes may signal Alzheimer's in the form of digital biomarkers.
A new study from Tel Aviv University (TAU) presents an innovative treatment for deafness, based on the delivery of genetic material into the cells of the inner ear. The genetic material "replaces" the genetic defect and enables the cells to continue functioning normally. They maintain that this novel therapy could lead to a breakthrough in treating children born with various mutations that eventually cause deafness.
Researcher Ryan Corey recently heard from a friend who teaches at a school where some of the students have hearing loss. The friend wanted to know if he had any ideas to help her communicate with these students while wearing a mask to slow the spread of COVID-19. Corey, who also has hearing loss, did not know what to tell her. So, he headed to the Illinois Augmented Listening Laboratory to look for solutions.
Researchers report that hearing loss and high blood sugar are associated with poor cognitive performance among middle-aged and older Latinos.
Since the beginning of the COVID-19 pandemic, there have been reports in the professional literature on possible hearing loss caused by the disease. A new study from Tel Aviv University (TAU), in collaboration with the Galilee Medical Center, finds no evidence of damage to the auditory system as a result of COVID-19 infection.
Listeners can extract a lot of information about a person from their acoustic speech signal. During the 179th ASA Meeting, Dec. 7-10, Tessa Bent, Emerson Wolff, and Jennifer Lentz will describe their study in which listeners were told to categorize 144 unique audio clips of monolingual English talkers into Midland, New York City, and Southern U.S. dialect regions, and Asian American, Black/African American, or white speakers.
Though face masks are important and necessary for controlling the spread of the new coronavirus, they result in muffled speech and a loss of visual cues during communication. Sandie Keerstock, Rajka Smiljanic, and their colleagues examine how this loss of visual information impacts speech intelligibility and memory for native and nonnative speech. They will discuss these communication challenges and how to address them at the 179th ASA Meeting, Dec. 7-10.
