The inductive hearing system from Telecom Behnke is a module designed to support hearing-impaired individuals in intercom systems. It enables the transmission of audio signals via a cable loop using electromagnetic waves, allowing speech signals to be directly transmitted to users' hearing aids. The device is made of acrylic glass, ensuring a clear and robust appearance while also facilitating integration into existing installations.

inductive hearing system

The system operates on the principle of inductive signal transmission, in which an electrical signal is converted into electromagnetic waves via a closed cable loop. These waves can be received by compatible hearing aids equipped with an induction coil. This enables direct and interference-free transmission of the speech signal without requiring additional cables or headphones.

application areas

The inductive hearing system is specifically designed for use in intercom systems, particularly in buildings with hearing-impaired users. It is suitable for apartments, nursing homes, hospitals, or public facilities where clear and understandable communication via the door intercom system is required. Installation typically takes place in the vicinity of the intercom system, ensuring the signal is receivable by all hearing aids present in the room.

functions and equipment in detail

The module consists of a cable arranged in a loop to generate a uniform electromagnetic field. The loop is integrated into the room, with its exact arrangement and length varying according to room size and requirements. The device itself is made of acrylic glass, offering high transparency and mechanical stability. The surface is smooth and easy to clean, meeting hygiene requirements in medical or care facilities.

technology explained simply

The technology is based on electromagnetic induction: the audio signal is transmitted through the cable loop as alternating current, generating a changing magnetic field. This field is received by an induction coil in the hearing aid and converted back into an audible signal. The transmission occurs without wireless transmitters or additional receivers, increasing reliability and simplifying installation.

compatibility and accessories

The system is compatible with hearing aids equipped with an induction coil (T-switch). These are typically standard in modern hearing aids. The cable loop can be adapted according to room size and requirements, with exact length and arrangement depending on the specific installation.

installation and mounting

Installation is typically carried out by qualified professionals in the field of low-voltage technology. The cable loop is integrated into the room, with exact positioning and length varying according to room geometry and number of users. Connection to the intercom system is made via existing terminals, with exact wiring depending on the specific system. Installation requires no additional tools or components, as the module is directly integrated into the existing system.

advantages in operation

The inductive hearing system provides reliable and interference-free communication for hearing-impaired individuals. Since the signal is transmitted directly to the hearing aid, no distortions or interference from ambient noise occur. Integration into existing intercom systems requires no additional hardware, simplifying maintenance and operation. The use of acrylic glass ensures an aesthetically pleasing and robust surface that blends well in various environments.
