A "noise light" is similar to a traffic light. It makes the colors green,
yellow and red from different sound levels (and similar to a traffic light,
green means "OK", red means "ALERT", and yellow is the transition state).

Note that this app is NOT a calibrated sound level meter, and is therefore NOT
appropriate for professional use.

You can adjust the thresholds for "Yellow" and "Red", depending on your
personal taste.

Also adjustable is the response time so that a level change does not lead to a
color change immediately. Only a certain duration of level changes lead to
color changes. This prevents single peaks of noise from triggering color
flicker.

"Red" can trigger an alarm using Text to Speech with text you can edit in
settings, or by playing an audio file from SD Card. You can set a fixed
volume, or use the media volume.

A click on the display (or optionally rotating it) shows some statistics.

There is also a log-file option with the possibility to visualize the recorded
data as diagram (when the display is rotated).

The maximun recording time is 10 hours. The log file (log.csv) is located in
the directory "Noise Light" on the SD Card and is overwritten each time the
app is started. As an alternative, several log files (date-time.csv) are also
possible.

In addition log files can be processed by programs like "Excel&Co".
