Abstract: It is well known that the per cent syllable articulation decreases with increasing distance between the speaker and the microphone or listener. It is shown that when a velocity-ribbon microphone is set so far behind a pressure-operated microphone that the recorded reverberation is the same for both microphones, the per cent syllable articulation remains unchanged. Attention is drawn to the undesirable effects of interference for steady tones, and mention is made of ways to reduce such interference.
