Abstract
Acoustic quality of a classroom is a term proposed to describe acoustic
properties that contribute to a subjective impression received by a human,
such as speech intelligibility, external noise, or vocal effort. It is
especially important in classrooms, where suitable conditions should be
provided to convey verbal content to students, taking into account their
age. The article presents a method for assessing the acoustic quality of
classrooms based on a single number global index and taking into account a
number of factors affecting the outcome of the assessment. Partial indices
are presented and their weights are proposed based on an analysis of
factors determining whether a room meets applicable acoustic requirements.
Results of the assessment of the acoustic quality carried out with the use
of the developed method in selected classrooms are also presented.
