When customers with hearing aid enter a bank, post office, railway station or similar, they are faced
with the problem of background noise and many people talking at the same time.
For this reason, it is difficult for bank or post office staff to communicate effectively across the counter,
especially across counters with security screens. These situations may cause confusion or embarrassment
on both sides of the counter.

The XL-Sound Service is a communication system that enables you to give these customers better
hearing. It consists of a mini microphone, a small amplifier and a loop pad. All the units can easily
be fitted inside the existing counter without disturbing normal working routines.

The generated magnetic field is arranged in such a way to give almost total secrecy.
