For the first two weeks of life, mice with a hereditary form of deafness have nearly normal neural activity in the auditory system, according to a new study by Johns Hopkins Medicine scientists. Their previous studies indicate that this early auditory activity — before the onset of hearing — provides a kind of training to prepare the brain to process sound when hearing begins.

Scientists can harness sound on other worlds to learn about properties that might otherwise require a lot of expensive equipment, like the chemical composition of rocks, how atmospheric temperature changes, or the roughness of the ground. Extraterrestrial sounds could also be used in the search for life. Timothy G. Leighton from the University of Southampton has designed a software program that produces extraterrestrial environmental sounds and predicts how human voices might change in distant worlds. He will demonstrate his work at the upcoming 184th ASA Meeting.

Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of the Augmented Listening Laboratory at the University of Illinois Urbana-Champaign. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements. They will describe the talking human head simulators, and their work investigating how humans receive sound and developing audio technology, at the 184th ASA Meeting.

At the 184th ASA Meeting, Emily Sandgren and Joshua Alexander of Purdue University will describe experiments to determine the best hearing aids for listening to music. To test and compare, they took over 200 recordings of music samples as processed by hearing aids from seven popular manufacturers. They asked study participants to rate the sound quality of these recordings and found that the hearing aids had lower ratings for music than their control stimuli. The researchers found bigger differences in music quality between hearing aid brands than between speech and music programs.

The 184th ASA Meeting will include three press conferences on Tuesday, May 9. The in-person presentations will also be livestreamed and recorded. Topics will focus on a wide range of newsworthy sessions, including 3D-printing head simulators, tracking immune cells with ultrasound, investigating the impact of skin color on breast cancer diagnosis, mimicking insects to create miniature microphones, and locating leaks in water networks. Reporters can register for in-person or virtual attendance.

Vestibular schwannomas related to neurofibromatosis type 2 (NF2) are difficult to manage and are sometimes treated with a noninvasive option, stereotactic radiosurgery. A retrospective study conducted by an international, multicenter team found that stereotactic radiosurgery is effective for patients with these tumors while preserving serviceable hearing and not causing radiation-related tumor development or malignant transformation.

Brian McDermott, a Case Western Reserve scientist, is reporting a discovery about unexpected asymmetry on the hair cells of zebrafish that allow them to detect movement with greater sensitivity from the back than the front. “This shows that fish have hair cells that are actually tuned to sense different water directions,” McDermott said. “In humans, our cochleas have hair cells that are similarly tuned to be able to hear different frequencies.” McDermott said the finding also advances our understanding of “the long-sought mechanotransduction (Mec) channel” in living creatures.

Global breakthrough: for the first time in the world, researchers at Tel Aviv University recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.

Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.
