Acoustical Design of a Conference Hall
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2009, Vol 6, Issue 2
Abstract
In the building of Caras Severin County Council from Municipiul Resita, capital of Caras Severin county, in Romania, was realized an extension and modernization of space located on the first floor where we arranged a conference hall with an exhibition space in the foyer. The beneficiary, Caras Severin County Council wanted this room to have an enviable architecture and modern technological equipment for conference and teleconference purposes, with facilities for simultaneous translation in at least two languages. The room who have to be arranged had deficiencies between the proportions of geometric dimensions, placement of large reflecting surfaces, windows on the corners room, the poor performance of sound insulation panels on the roof, all these negatively impacting the quality sound. The present paper refers the solutions for acoustical design (sound insulation and perception acoustics) of a conference hall, adjusted to the aesthetic demands of the architecture. We will present the acoustic specifications we would like to achieve for reasonable performances regarding the use for the space. We opted for the acoustic environment of a diffuse field. For this purpose we used moreover for acoustic treatment the sound absorption material and sound diffuser material. Concerted efforts of the architect, acoustic specialist and other specialists involved in planning have led to a conference hall with both architectural and modern technological equipment, with good acoustic qualities, good speech intelligibility even without electronic amplifying the sound.
