Scope

This section specifies the method for determining the electroacoustic performance of hearing aids equipped with inductive pickup coils used in audio magnetic fields. The characteristics of the inductive pickup coils are measured by simulating the operating state of the loop in the room where they are used.
Note: The characteristics of the inductive pickup coils in telephone magnetic fields may differ from the results measured in this section.
