Hearing Aid Server (Modular Type)

01
The hearing aid server can convert the received train broadcast audio into voice electrical signals and output them to the loop coils installed in the carriage. The magnetic induction signals generated by the loop coils can be received by hearing aids or assistive listening headphones with the "T" setting (comply with the IEC 60118), and then these signals are converted back into sound for the users to hear, thus providing assistance for people with hearing impairments during their travels.

Product Features

  • Good Concealment

    The audio loop coils are laid inside the walls, which will not affect the overall aesthetics of the subway or the normal operation order. Moreover, it will not pose an obstacle to passengers' activities.

  • Strong Stability

    It adopts mature electromagnetic induction technology, which is less affected by external environmental factors. It can operate stably in the complex subway environment, ensuring the continuous and reliable transmission of audio signals, and providing stable hearing support for the hearing-impaired.

  • User-friendly

    For people with hearing impairments, they only need to switch their hearing aids to the T position. Once they enter the coverage area of the audio loop, they can automatically receive the signals without the need for complicated settings and operations.
