3 Overview

A pure tone audiometer is a measuring instrument used to determine the human ear hearing threshold and provide a basis for diagnosing auditory disease. widely For hospitals, rehabilitation centers, deaf schools, mining, military and disease prevention and control centers and other institutions. According to the lowest strong System of functional requirements, pure tone hearing score is divided into four different types. 1 type --- for advanced clinical diagnosis/research; 2 type --- for clinical diagnosis; 3 type --- for basic diagnosis; 4 type --- for screening/monitoring. These four types And their application of the scope of the design. Pure tone hearing meter composition and basic working principle shown in Figure 1.
