1, Introduction
Hospital is a place for people who suffer from illness and
need high concentration, so they need uiet atmosphere and a
place that is far from noisy condition. 4nconsciously, the
visitors in hospitals usually talk in loud voice. Although
there
are some poster and hospital staff who warn the visitors,
!ut
they still talk in loud voice. #t will distur! patients. "ased
on the
pro!lem a!ove, the authors get an idea to create SOS$%&'
device which can !e as detector and notifier of noisy
condition
to the visitors in hospital automatically.

"ased on the !ackground, the pro!lem statement in this
research are
&. How to make SOS$%&' device which can !e detector
and
notifier of noisy condition5
6. Can SOS$%&' detect noisy and notify the noisy maker
