Areas demanding special acoustic attendance
The importance of good acoustics in schools and other premises has been clearly demonstrated by research projects in Sweden (Lund Institute of Technology) and in UK (Heriot-Watt University in Edinburgh).
In situations involving communication to or with an audience, it is particularly important for the speaker to be clearly heard and understood. A great deal of extraneous sound can compete with the spoken word. Ventilation noise, scraping chairs, footsteps, rustling papers and undesirable sound reflections are typical sounds that threaten the intelligibility of speech.
