The effect of speech and speech intelligibility on task performance

Article Abstract:

A study was conducted to find out the effects of three different sound environments (speech, masked speech and continuous noise) on performance of cognitive tasks of varying complexity. Subjects assessed `speech' as most disturbing, subjective arousal was highest in masked speech and lowest in continuous noise, while continuous noise annoyed the least, suggesting that performance in real open-plan offices could be improved by reducing speech intelligibility.
