Signage is an ADA Requirement for Effective Communications
Signage is a critical component of every assistive listening system. Simply put, proper signage lets people (staff and visitors) know where the systems are installed and how to use them – for everyone’s benefit.
Good signage always makes good sense and, in this case, it’s required by the 2010 ADA Standards for Accessible Design that went into effect on September 15, 2010. See below, taken from Chapter 7 of the Standards.
703.7.2.4 Assistive Listening Systems. “Assistive listening systems shall be identified by the International Symbol of Access for Hearing Loss complying with Figure 703.7.2.4.”
Adding the “T” in lower right corner is the internationally recognized symbol for hearing loop systems. It lets people know to switch to the “T” mode on their hearing aids, cochlear implants, bone-conduction devices and other Telecoil/Loop receivers.
