Abstract:
A new range of values for the early decay time (EDT) given in 1/1 octave band is proposed. With the objective of studying an acceptable EDT range from the point of view of the students satisfaction with the acoustic quality of classrooms, acoustic measurements were carried out in classrooms of Brazilian schools located in the metropolitan area of Greater São Paulo. Questionnaires were administered to the students of those classrooms in which the measurements took place in order to assess the occupants’ satisfaction with the rooms. The results of this research indicate that the classical limits are more conservative, except when compared to the auditorium limits of ISO 3382-1 (2009).
