In a busy area like NYC where subway stations are always crowded , navigation for a person with hearing impairment can become quite uneasy. Canceling all the unnecessary noise while asking for directions or seeking more information about oncoming trains can be a daunting task.
Thanks to a device called “hearing loop” being introduced all over the city, hearing only what is important without unnecessary noise is becoming quite possible. The loop is placed close to a room or a window and sends out signals which are caught by a “t-coil” which is already inside many hearing aids and cochrain implants. The t-coil eliminates all the background noise and picks up only what is coming out of a microphone or speaker.
