ADA Calculator, ALD Locator and other information to help you understand the ADA requirements for assistive listening.

Navigating through the requirements of the Americans with Disabilities Act (ADA) can often prove to be a challenge for organizations to easily understand the intent of ADA, in particular Title III and providing assistive listening devices for hard of hearing people.

Here is a handy locator that will help you find venues that have assistive listening technology installed. You can search by FM systems, Infrarad systems, or Hearing Loop systems and find venues zip code or city and state.

Below on this page you will find several ADA calculators -an online version, a downloadable PC version, and where to get our smart phone ADA applications for both Android and iPhones. Also on this page are an interactive white paper, ADA systems overview, and Table 219.3.

Listen ADA Systems Overview

Listen offers three FM (RF) ADA systems and one Infrared ADA system. Compliant with today's Department of Justice Title III of the ADA for assistive listening systems, each of the Listen ADA systems provide all the necessary components to meet the new standards for the minimum number of receivers/ALDs required based on the capacity of seating of assembly areas. And, they also meet the standards for the number of receivers/ALDs that are required to be hearing aid compatible. See table below.

All systems can be installed for use in assembly areas where audible communication is integral to the use of the space. Ideal for classrooms, public meeting rooms, public hearing rooms, legislative chambers, motion picture houses, auditoria, theaters, playhouse, dinner theaters, concert halls, centers for performing arts, amphitheaters, arenas, stadiums, grandstands, or convention centers, and more.

The Infrared system delivers a secure, interference-free audio signal.

Systems are available for a free 30-day no obligation demonstration. All four systems are available for shipment immediately. Systems are backed by a Limited Lifetime Warranty.
