•SOUND METER
The sound meter measures the level of sound in the immediate vicinity of
your phone, giving an approximation of the actual decibel level. The sound
meter provides general measurements for personal use that may vary
from scientific measurements. The vertical bar scrolls up and down,
showing the changing noise level. The number in the upper box shows the
peak value in decibels. The number in the lower box shows the current
sound level in decibels.
Note:
The sound meter cannot be used when a headset is
connected to the phone.
