People with hearing impairments in life have to constantly deal with a variety of sounds in public places. Noise in spacious premises does not parse incoming sounds. This problem is solved by an induction loop. It allows high-quality, no distortion of the external acoustic conditions to hear the voice of the interlocutor.

Induction loop for the hard of hearing — what is it?

There are additional devices for people with hearing impairments who have gained the trust in many countries.

Induction loop is a device that transmits audio signals (e.g., music, television show, radioavisen) without noise interference on hearing AIDS hearing-impaired persons.

Built-in telecoil in the hearing aid receives the signal of system with induction loop. It is necessary to switch the mode to “reel” (T).

Main components of the induction system

  • Induction loop for the hearing impaired. What it is discussed above.
  • Amplifier for induction loops is an auxiliary device designed to create fields of the same name.
  • A field Indicator, designed for installers of induction fields.
  • Microphone.
  • The Brackets for mounting the device.

The Induction system is installed in concert halls, airports, cinemas, schools, theatres, churches, lecture halls, railway stations and other objects. Those who wear behind the ear hearing aid, are given the opportunity to interact with people in public places and obtain the necessary information.

A Professional induction system

They are designed for large spaces (churches, meeting halls, theaters, airports) and are characterized by high power and frequency.

induction loop for the hard of hearing what's this

Basic requirements:

  • High clarity of sound for people wearing hearing devices;
  • Optimal sound quality in the middle of the field induction loop;
  • Minimal interference from metal structures in buildings;
  • Setting the indicators of the boundaries of the zone of admission of the signal.

The System has the function of automatic power control gain, the result is a stable constant field strength level with high speech perception during external disturbances.

Systems for a narrowly defined use with induction loop

The Radius of the induction system is about 1.2 m. such systems use an insole with an induction loop and microphone. They are wireless, and set them in a small room is not difficult. System designed for use in banks, ticket offices, hotels, banks supermarkets. They help hearing impaired people to establish a dialogue with the staff.

Portable induction system

For meetings, conferences and negotiations used a portable system with induction loop. To do this, around the perimeter of the stretched cable. The innovative device contains an induction loop, cable, amplifier and wireless receiver.

Portable induction loop system

Advantages of portable induction systems

The convenience of the use of instruments is undeniable. These include:

  • Built-in microphone;
  • Wireless system;
  • Compact;
  • Built-in module of interfacing equipment to connect audio devices directly to the connector on the amplifier;
  • Battery;
  • Interesting design;
  • Mobility (ability to migrate to other areas).

The Range of induction loops, depending on the purpose, from professional application in the spacious rooms to compact handheld devices. The use of induction loop allows people with hearing loss to navigate in a sound environment with constant high noise levels.
