I have a pair of noise canceling head phones. When turned on you adjust
for normal hearing. When there is a loud noise they shut off instantly.
If I clap my hands loudly in a small room I can only hear the echo of the
clap after they return to normal status.

If you buy "today" at Rockler's Deal of the Day site.,,

Might I add that mine are strictly hearing protection and have no radio
built in.
