Apparatus of Measuring Hearing and Hearing for Mechanics Physics Lab

This Apparatus of Measuring Hearing and Hearing for Mechanics Physics Lab is designed for studying human auditory perception and determining the hearing threshold of the human ear. The apparatus enables users to investigate hearing sensitivity across a wide range of sound frequencies and intensity levels using a precision signal generator, audio amplification system, and monitoring-grade headset. Through practical experimentation, students can construct hearing threshold curves, analyze auditory response characteristics, and gain a deeper understanding of hearing mechanisms and audiological measurement techniques. The system provides an effective platform for education, medical physics studies, and introductory audiology training.
