Specification of Performance Measurement of Hearing Assistance Devices/Systems
This standard defines various types of HADS and describes procedures for measuring their performance characteristics. These procedures are useful for comparing the performance characteristics among various HADS. This standard addresses the measurement of the output characteristics of HADS regardless of the method of transmission. Whenever the device/system is capable of transmitting signals using two or more transmission methods, this standard requires that the output of the device/system be measured using each transmission method.
