Endlich Ruhe im Hort! Eine akustische Muster-Installation nur in den Raumkanten

Quiet in the school, at last! An acoustical model installation in merely the room edges.

Substantial complaints about deficits in education, loads on teachers and tutors as well as subsequent losses due to various diseases have raised the general awareness of noise levels in tuition and care utilities. To cope with this omnipresent problem, constructional measures are required which can provide environments for a relaxed communication among numerous users without necessarily raising their voices. Here a room-acoustical model installation is presented which has solved the problem by means of broadband sound absorbers concentrated in only the edges of a day-nursery of a public elementary school. These 'edge absorbers', especially designed for this purpose, are easily installed and simply refurbished in the same way as rigid ceiling or wall surfaces. The subjective assessment of the achievements by those responsible and the users themselves are backed by objective measurements of the reverberation spectra for four different acoustic conditions in the room. The report finally calls for a reinforced public and private engagement in this field.
