Sennheiser SpeechLine – True the word

8 | SpeechLine IS microphone series

Typical acoustic situations

A) Normally attenuated room

A normally attenuated room provides an average attenuation of

reflecti

ons. This is contributed to by carpets, curtains or special acoustic

ceilings. In the case of reduced reflections in the room, microphones pick

up less noise, which results in the highest speech intelligibility.

B) Room with amplified sound

If the speech in the room is amplified by

loudspeakers, this signal can enter

the microphone again. This can cause echo, but in the worst case acoustic

feedback can be the result. The effect can be reduced by using

microphones with stronger directional characteristics.

C) Large rooms with echo – acoustically challenging rooms

The larger the room, the more probable i

s acoustic disturbance due to

reflections or sound coming from loudspeakers. If the room also has many

smooth surfaces such as glass fronts or smooth floors, the result is a

scenario which is extremely unfavorable acoustically. In this case, only

microphones with strong directional characteristics like the ME 36 can

ensure speech intelligibility.
