Abstract:
The room acoustics of twelve classrooms in a school building have been
investigated. The building was designed in an organic style of
architecture encompassing a different floor plan for each classroom in
order to fulfil the diverse needs of children of different ages. Room
acoustical conditions were of great importance for the architect.
However, as a consequence of limited funds, simple solutions were
required.
A set of room acoustical parameters has been measured in three
classrooms. Reverberation time and speech transmission index STI were
in good accordance with today's requirements. In some rooms the
reverberation times are somewhat lower than the recommended lower limit
for children of normal hearing.
As a supplement to the measurements, a questionnaire survey of the
teachers was carried out. The goal was to learn how the acoustics in
the classrooms were accepted. The teachers stated that they were highly
satisfied with the acoustical conditions, not only with regard to
speech but also for playing music.
But considering the concept of the interaction of all the senses and
the influence of a living architecture conditions for learning in the
classroom should not be evaluated only by the acoustical situation but
also by the other sensory aspects of the room.
