Hearing thresholds refer to the minimum sound intensity required for an individual to perceive a sound. This area of research focuses on understanding and measuring the sensitivity of the human auditory system, particularly in regards to detecting and distinguishing between different levels of sound. Researchers investigate how hearing thresholds vary across different frequencies, ages, and populations, and how factors such as noise exposure or genetic predisposition can impact an individual's hearing sensitivity. By studying hearing thresholds, researchers aim to improve the diagnosis and treatment of hearing disorders and develop strategies to prevent hearing loss.
