below to adjust
Fm volume
setting to proper level. Two
people are needed to set the volume
level. It is difficult to hear your own voice
and make adjustments to it.
note:
The average volume setting is
in the 3 position (see photo), but may
change depending on room acoustics and noise level.
1. With a sound level meter
- Take a level reading in the center of the room during
normal classroom activity, and another reading of the teacher's amplified voice (without
the class activity). The level of the teacher's voice should be set between 10 - 15 decibels
above room noise level.
2. Without a sound level meter
- First, ask someone other than yourself (if you are the
teacher) to listen to the amplified voice and make volume adjustments. An ideal volume
level is achieved when the listener can hear the amplified voice at a comfortable level and
the volume level from the speaker and teacher’s mouth is comparable. If you can hear
yourself through the loudspeakers, the volume setting may be too high and should be
decreased.
