Launches Assistive Listening System


Wireless audio system allows teachers to tailor instruction for all students

Helping teachers to individualize instruction and meet the needs of all students, Califone International, Inc., launches its newest product designed specifically for use in educational settings, its Assistive Listening System.

The Assistive Listening System enables educators to provide to any number of designated students with a listening device to clearly hear the teacher or other amplified audio. For use in larger settings such as in auditoriums or outdoor applications like field trips, it means that specific listeners can receive extra audio support, whether that means by increased amplification or tailored for a tour group activity. In smaller areas, the system combats inadequate classroom acoustics and high levels of ambient noise, thereby increasing engagement and achievement. Though kit sizes vary (and are configurable for any size group), the core of the system includes a 900 MHz transmitter for the presenter that can be fitted with either a headset or mini condensor microphone, and any number of wireless receivers (with connecting headphones) for listeners. The receivers feature dual headphone jacks so one can be shared with a classmate. This also makes the system helpful for those who need translation support, such as for non-English speaking parents at back-to-school nights. Listeners can choose between a lightweight headphone or a single ear headphone attached to the receiver. The receivers and transmitter can be worn with a lanyard around the neck or hip worn with its belt clip.

Can be configured for any group size or application, such as for a 10-Person Assistive Listening or a Tour Group.

Unique to this system, and many Califone products, the Assistive Listening System incorporates a volume restriction feature.  Under guidelines recommended by the American Speech-Language-Hearing Association (ASHA) and the Occupational Safety and Health Administration (OSHA), the receiver’s volume can be set not to exceed 85 decibels. Many studies show that extended exposure to high levels of noise can cause irreparable hearing loss, leading Califone to design this system with student safety in mind.

This new listening system is ideal for tour groups and wherever it is imperative that all students can hear the teacher clearly, despite language barriers or disabilities,” said Tim Ridgway, VP of marketing for Califone.

The Assistive Listening System comes with a charger and carrying case for easy use and storage.  The system is available in a variety of packages so technology directors and educators can select the solution that best fits their specific needs.

Califone will showcase the Assistive Listening System at InfoComm, June 9-11, 2010, in Las Vegas, NV (Booth #N1429) and during ISTE, June 27-30, 2010, in Denver, CO (Booth #1189).
