Essay on Acoustic Design in Architecture.

Introduction
The purpose of this report is to produce a design scheme for the conversion of a large room to a multi use theatre. The report will present the necessary things that need to be considered to ensure a satisfactory acoustic environment by measuring the problems encountered with acoustic design and how to tackle them. The report will look at the problems related to this space and present possible solutions and recommendations based on the information available.

The stage will be best positioned at the centre of the east wall, as shown in Fig.1 The audience depth will be shallow and wide so that the best can be appreciated from a presentation or performance both visually and acoustically.
