This instrument is suitable for medical undergraduates and postgraduates to measure the threshold curve. In general, the definition of pain threshold should reach the ear pain, but students only need to understand the principle of the experiment, and when measuring the pain threshold, they only need to adjust the sound pressure level to the ear and feel unbearable. Through the experiment, students can understand the physical knowledge of sound intensity, sound intensity level, loudness, loudness level and auditory curve, and lay a good foundation for the application of clinical audiometry in the future.

Functions

1. Master the measurement method of hearing and hearing threshold;

2. Determine the hearing threshold curve of the human ear.
