Equalizer Applications
Conferencing room acoustics vary based on room size, shape, and construction materials. Use the guidelines in following ta
ble.
EQ Application
Treble boost for improved speech intelligibility
HVAC noise reduction
Reduce flutter echoes and sibilance
Reduce hollow, resonant room sound
Suggested Settings
Add a high shelf filter to boost frequencies greater than 1
kHz by 3-6 dB
Add a low cut filter to attenuate frequencies below 200 Hz
Identify the specific frequency range that "excites" the room:
1.
Set a narrow Q value
2.
Increase the gain to between +10 and +15 dB, and
then experiment with frequencies between 1 kHz and
6 kHz to pinpoint the range of flutter echoes or sibi
lance
3.
Reduce the gain at the identified frequency (start be
tween -3 and -6 dB) to minimize the unwanted room
sound
Identify the specific frequency range that "excites" the room:
1.
Set a narrow Q value
