For inter-ear communication between hearing aids, a BER better than
10

-3

is required . The communication is updated every 50 ms (or 20 Hz) .

The hearing aids continue to amplify based on the last saved settings
even when the transmission range is exceeded or when communication
is interfered .

Wireless Security Measures

Security of the wireless signals is assured through device system design
that includes:

• Individual MAC address for each unit which is checked during each

transmission .

• A built-in pairing table which specifies valid and legitimate pairing

among units

• A proprietary Widex communication protocol which checks the package

numbers during each transmission .

• A Cyclic Redundancy Check (CRC) to check data validity and correct

errors .
