Lecture: A case study on Irrelevant Speech Effect assessment at open plan offices using Equivalent Modulation
Author(s): Borin Marcel, Monteiro Carolina, Leite Debora
Summary:
The emergence of recent standards for open plan offices has led to the development of new metrics to measure noise annoyance and decrease in performance at workplaces. The main existent models deal with the ambient noise as a single number (LAeq) and as a stationary signal. However, they are not completely effective, once the speech levels in an office fluctuates during the day. Kostallari has recently developed a method to assess the Irrelevant Speech Effect (ISE), which is called Equivalent Modulation (Meq), that is based on the depth of modulation of the signal. In this paper, in situ measurements were conducted together with a questionnaire and performance test experiment aiming to correlate the effectiveness of Meq in representing the Irrelevant Speech Effect.
