Which audio device should I use?

The appropriate audio device depends on your setup. Take the following rules of thumb into account:

  • For room settings, use one omnidirectional ceiling microphone.
  • For meetings around a table, use one boundary layer table microphone.
  • For usability research behind the computer, use a microphone close to the test participant, for example a wireless microphone or boundary layer table microphone.
  • For very good audio quality for more than one test-participant, use a wireless microphone for each person.
  • nAudio quality strongly depends on the room settings. An expensive audio device does not by itself guarantee good audio. If the devices are not placed correctly, or if the acoustics in the room is bad, audio quality will be suffer.
  • Do not place the microphone cables in the vicinity of 230 V electricity cables. If you, for example, placeroute microphone cables in electrical conduits, the electricity can interfere with the audio.
  • Use,Use sound absorbing material, like curtains, to avoid echoes on audio recordings.
