Field amplifies the sound and wirelessly sends it to the hearing aid. Therefore, you can turn up the volume without having to consider disturbing the rest of the household or neighbours.With the help of a boundary microphone placed on the table, Field can also be used for conversation or meetings. As an alternative to the included room loop, Field can also be used with a cushion loop. A cushion loop is recommended in apartment blocks to avoid disturbance from other teleloop systems.
