Why Meet the IEC Standard for Hearing Loop System Installation?

(2 pages) When loop systems do not meet the IEC standard, the users receive insufficient benefit and criticize the loop in the following ways:
1. Those who have used the loop system say they can hear better with their hearing device.
Cause: Poor frequency response, low signal level or too much background noise.

2. Those who have tried the loop system say that the volume is too low.

The loop system’s magnetic field is uneven resulting in low signal and/or varying strength throughout the seating area. In addition, the loop wires are placed too far apart.

etc.
