Hints: Measurement

Select measurement positions as stipulated by local regula-•

tions. As a guideline, typically position the microphone at 1

- 1.2 meters above ground in sitting areas or 1.5 - 1.8 meters

in standing areas. Also, directly in front of the speakers or

very close to a wall are examples of positions that are not

typical.

The person taking the measurements should be out of the •

acoustic ﬁeld, so as not to affect the measurement results.

For this purpose the measurement microphone can be

mounted on a microphone stand and connected with the

ASD Cable to the XL2.

Low speech intelligibility readings can be caused by•

Excessive sound reverberation, echoes or reﬂections

Poor speaker directivity or speaker coverage

Speaker level setting incorrect; e.g. low signal-to-noise ra-

tio.
