Whether in a classroom, lecture, or meeting room, hearing aid wearers face a real challenge understanding the speaker clearly amongst surrounding background noises.
This is because hearing aids are unable to focus on a specific sound due to the way they pick up and amplify all of the other sounds present in the room.

The EXP-ASL system addresses the needs of multiple hearing aid wearers in classroom, lecture and meeting room settings, providing them front-row sound level and clarity up to 25 meters away from the speaker.

Worn by the speaker on an adjustable neck cord, the FM Microphone/Transmitter features a unique patented technology that increases the available sound level and at the same time, reduces unwanted background and peripheral noise by up to 30 db, allowing hearing aid wearers to hear the speaker clearly.
The desired sound is transmitted with enhanced clarity to the Pendant Receiver (worn around the user's neck either above or below clothing), which sends the signal to the hearing aid.

By removing background noise, the desired sound is much clearer and intelligible, even in noisy classroom or meeting situations.
By increasing the available sound level, less strain is placed on hearing aid amplifiers, eliminating distortion and feedback. As a result, hearing aid wearers can take a more active part in classroom discussions, lectures, and meetings, without the frustration of not hearing properly.

The EXP-ALS also allows a set of headphones to be connected to the receiver enabling the system to be used by non-hearing aid wearers.
