(from HLAA webpage on HAT)

Hearing Assistive Technology, or HAT as it is commonly referred to, is technology that can help in various listening situations.

Often, a hearing aid or an implant is not enough in certain situations. In such cases, there are technologies that are designed to help people with hearing loss. These are designed to enhance telephone communication, TV reception, ensure an effective smoke alarm, or listening in various kinds of public venues. Your hearing professional should evaluate your need for one or more of these devices and direct you to the appropriate vendor.

Some basic information along with a brochure on hearing assistive devices is available at the above link.

As a matter of policy HLAA does not endorse one technology over another. We provide information about all types of technology to our members and anyone with hearing loss looking for help.
