To Whom It May Concern:

As a blind person who has traveled independently for many years I feel it is my responsibility to give input to the Access Board about audible signals and detectable warnings at every intersection.

I have traveled independently with my white cane for many years. When I first encountered audible signals I found them totally distracting rather than helpful. I need to listen to the flow of traffic, and the "chirp chirp" of these signals masks the sounds of the traffic flow.

This is an extremely important issue to me and many of my blind and visually impaired friends.

Sincerely,

Frida Aizenman
