Space Noise And The Separation Of Noise Generated Within The Buildings

Decent Essays

The major acoustical issues in public buildings are concerned with the exclusion of outdoor noise and the separation of noise generated within the buildings. This chapter will consider specific types of public buildings in which acoustic designs are a matter of importance, such as schools, offices, libraries, recreational buildings, hospitals and government buildings. To obtain a space free from the annoyance of noise and excessive reverberation, a few step one could take would be as follows: planning the build with consideration of noise insulation so that rooms which contain sources of considerable noise level are separated from rooms that are required to silent; providing sufficient noise insulation for rooms where silence is need as well as implementing sound absorption to reduces the reverberation and noise created by that room to a more acceptable level. It is well to recognise that uncontrolled noise in public buildings will diminish their utility

Since the dawn of the twenty-first century, public school have shown more attention to acoustical problems in part due to the increased use of open planning, more informal teaching methods and an increased use of audio-visual aids. Classroom acoustics should neither be too high nor too low, but rather a balance of reflective finishes to aid teaching and absorptive finish away from the front of the classroom to avoid sound-blurring cross reflections. The UK recommendation on the decibel level in classes is at 40dB however a
