Building Acoustics and Daylighting Buildings

FAST-NHB045Acad. year: 2020/2021

Inside the building is necessary to provide acoustic and visual comfort. In terms of noise insulation is necessary to deal with both vertical and horizontal structures. Horizontal dividing structure, ie the ceiling to the floor, or even below, we shall, in addition air and impact sound insulation. The room acoustic enclosure is rated in terms of reverberation, in the field of urban acoustics belong determining attenuation in the outdoors. Aperture fillings in the peripheral and roof cladding must ensure adequate lighting interery daylight and the insolation.
