In a crowded restaurant, the sounds of conversations bounce off walls, creating background noise. Each individual wants to be heard, so they end up talking a little bit louder, which increases the overall din. Eventually – barring an interruption – the system gets loud enough to reach the limit of the human voice. Braxton Boren will discuss this cycle, called the Lombard effect, and how it can be disrupted in his presentation, "A game theory model of the Lombard effect in public spaces."

Hearing-impaired people whose auditory nerve is still intact can often be helped with a cochlear implant. But inserting the implant into the inner ear is not without risks, as facial nerves can be damaged in the process. Empa researchers have developed a novel smart drill that minimizes the risk by automatically shutting off when it comes near nerves.

A new multicenter study will use artificial intelligence (AI) to analyze pre-surgical brain MRI scans to predict individual-level language outcomes in English- and Spanish-learning children up to four years after cochlear implantation. The long-term goal of the research is to customize therapy to maximize children’s hearing and language ability after receiving a cochlear implant.

In The Journal of the Acoustical Society of America, scientists explore how digital health solutions can expand audiology services in clinical and research settings. Audiology assessment via telehealth would allow patients to access care while a specialist is located hundreds of miles away and, as a research tool, telehealth would allow for more representative and decentralized data on hearing, without compromising results. The team is currently scaling up several studies they conducted in rural areas of Alaska; their mission is to close the gap on hearing health disparities.

An artificial-intelligence (AI) model built at Mass Eye and Ear was shown to be significantly more accurate than doctors at diagnosing pediatric ear infections in the first head-to-head evaluation of its kind. The model, called OtoDX, was more than 95 percent accurate in diagnosing an ear infection in a set of 22 test images compared to 65 percent accuracy among a group of clinicians who reviewed the same images.
