Skin-attachable auditory sensor that functions even in noisy environments

Face masks, a new normal since the onset of the COVID-19 pandemic, muffle sound, making it difficult to understand speech. People often have no choice but to speak louder and strain their throat muscles. This communication stress may hinder rapid response in a hospital setting, fire emergency, or other urgent situations. Fortunately, a research team has recently developed a new intelligent microphone that will enable smoother communication in such events.
