2N® Induction Loop

An effective communication solution for those with a hearing disability

The 2N® Induction Loop is an electric device that transmits sound wirelessly from a 2N Helios IP intercom to the hearing aid of a person with a hearing disability. On connection to an audio source, it allows people with a hearing disability to hear and perceive sounds much more clearly. By installing an induction loop at the door, you not only comply with required regulations, but you also allow hearing aid users to communicate with reception, for example, via the intercom. For this reason, the 2N® Induction Loop is an invaluable aid when resolving the accessibility of public and private areas.

Product highlights:

We also offer the 2N® Induction Loop as an independent unit, which can be used with any device emitting an audio signal. An example of this may be lift communicators or intercoms at a counter. It will find particular application in public buildings (for example offices, banks, hospitals or schools) or at information and sales centres.
