extracted text: EAR PADS of sponge rubber are
the latest style for British air-
raid wardens, members of Local
Defense Volunteers and other
workers who must remain out-
side shelters and continue their
work during air raids. They can
easily be fitted over a respirator,
and are said to disperse the
blasts from explosions before
they reach the eardrum, yet let
the wearer hear conversation.
