![]() ![]() ![]() Two subjective studies were then pursued, first to determine if auralizations made with an increasing number of channels sound more realistic and have an increased perceived source size, using solo musical instruments of varying directivity indices as the sources. Large differences in the values were found between the different sections of the sphere, on the order of several just noticeable differences. First an objective evaluation was conducted to examine how acoustic parameters, such as reverberation time, vary when using “quadrant” (one fourth of a spherical source) or “thirteenth” sources to create the binaural room impulse responses. This paper presents investigations employing an auralization methodology known as multi-channel auralizations, to determine the benefits of using an increasing number of channels in such auralizations. RT value of lecture hall reduce from RT=3.5 Hz to RT=0.95 Hz and the range of energy consumption reduce in hall after these treatments 70%.Īuralizations are commonly used today by architectural acousticians as a tool to model acoustically sensitive spaces. It helped to enhance acoustic and thermal performance level in hall and increasing sentiment of acoustic and thermal comfort in hall. #CATT ACOUSTIC V8 SOFTWARE#This research get down to the role of acoustic, architecture and thermal treatments to enhance acoustic and thermal performance of internal acoustic and thermal environment for main lecture hall of Tanta engineering whereas, the hall suffers great acoustic and thermal problems, all because of several reasons, most important it, sky light of ceiling, integration work done between acoustic and thermal treatments to achieve best acoustic and thermal performance and using ODEON software to evaluate suggested treatments acoustically and selection the best then evaluate it by DESIGN BUILDER software to calculate the range of energy consumption reduce in hall after these suggested treatments. RT value of lecture hall reduce from RT=3.5 Hz to RT=0.95 Hz and the range of energy consumption reduce in hall after these treatments 70%.Īcoustic and thermal performance greatly affect in lecture halls as, acoustic, architecture and thermal treatments play an important role to enhance acoustic and thermal performance in space and therefore increasing sentiment of acoustic and thermal comfort in space. Journal of Architectural Engineering Technology Journal of Architectural Engineering Technology Abstract Acoustic and thermal performance greatly affect in lecture halls as, acoustic, architecture and thermal treatments play an important role to enhance acoustic and thermal performance in space and therefore increasing sentiment of acoustic and thermal comfort in space. ![]()
