Microphone Placement

The closer the microphones are to the participants within a conference, the more natural and intelligible the voice

will be to the far-end participants. For optimum audio performance, the microphone should be placed at no more

than 50% of the critical distance. A microphone’s critical distance is the distance from the talker to the

microphone in which the direct audio signal is the same intensity as the reflected audio (see diagram).

The EasyMic MicPODs use three unidirectional condenser elements to provide 360 degree audio pickup pattern

within the room. In general, the EasyMic MicPODs should be placed in a location that minimizes the distance to

the majority of the participants (talkers) within the room. The closer the MicPOD is to the participant the better

the sound quality produced. The EasyMic MicPOD table mic pickup diagram below can be used as a rule of

thumb for sound quality versus talker distance. Performance may vary depending on room acoustical conditions.
