Human hearing is not a sophisticated instrument that treats all frequencies equally, but rather a perceptual system profoundly shaped by factors such as physiological structure and age. Healthy young people can typically hear sounds between 20 Hz (low frequency) and 20,000 Hz (high frequency), but their sensitivity to different frequencies varies. With age, the ability to perceive high-frequency sounds, in particular, gradually declines, a condition known as "age-related hearing loss." Furthermore, daily exposure to environmental noise can cause irreversible damage to hearing in specific frequency ranges. Therefore, each person's audible frequency range is like a unique biological fingerprint, silently recording their physiological history and life trajectory. Our interactive "Hearing Test" exhibit offers a scientific opportunity to explore your personal auditory world within a compact and private testing station (1314*986*975mm).
