When do I need protection?

With SoundMeter+, if user sees a display item flashing on screen, he should leave the environment right away, wear hearing protection devices, or minimize his stay time.

Specifically, if the message says "Risk of hearing damage! Less than 1 hour/day!", user should NOT stay there more than one hour.

Even without SoundMeter+ at hand, user should NOT stay long if

• User has ringing or pain in ears.
• User cannot hear a person 3 feet away.
• Speech starts to sound dull.
• User is forced to raise his/her voice to be heard.
