In modern rail networks to communicate with the passengers is used a full range of sound communication devices. Thanks to it, passengers can use rail communication with greater confidence and ease. However it's not applicable 4 million hearing impaired Poles having problems understanding the messages in the conditions of railway stations and on trains, where often is present reverb and high noise level. Improve the services offered to users of hearing aids and the fulfillment of the requirements laid down in the provisions concerning persons with disabilities can be achieved by effective hearing loops (induction) in all sound communications systems. In each type of audio communication with passengers hearing loops of Ampetronic provides significant benefits for rail customers, not only for hearing impaired people. Induction loop is a solution supporting speech understanding by providing high-quality, intelligible sound received by the hearing impaired.

Induction loop transmits the audio signal directly to the hearing aid, which significantly reduces background noise, reverberation and other acoustic problems hindering understanding sounds. Induction loop is the only system that does not require the purchase and maintenance of receivers for users due to the fact that most hearing aids have built-in receivers of induction loop. As a result it is the only effective solution for use in areas such as railway objects where users are temporarily.
