“…The volume of an auditorium is a key determinant of the quality of sound in an auditorium. According to [27], the air volume per person is a primary indicator for speech quality. For speech-oriented rooms or auditoria, the recommended volume (m 3 )/per person should be between 3 and 5 [27] while the optimum air volume for music (opera) halls should be between 6 -8 m 3 /person [20].…”

“…The KSB auditorium which is a speech auditorium, however, has an air volume per person of 12.2 which far exceeds the optimum recommendation for a speech hall which is 3 -5 m 3 /person. This is likely to cause a longer than optimum reverberation time unless other acoustic design interventions are taken such as the dimensions and material properties of the auditorium boundary surfaces to regulate the reverberation time to optimum levels as suggested by [27].…”

Auditorium buildings are special structures needing much attention for it to function properly. Generally, consideration should be given to seating, sightlines, and acoustic requirements. In addition, the design should ensure performer-audience intimacy as much as possible. The focus of the study is to review design strategies for auditoria on the Kwame Nkrumah University of Science and Technology, Kumasi campus towards compliance and to develop solutions for improvements that will enhance the performance of 4 selected auditorium facilities. Case study, observation and measurements were the main strategies used. The results revealed that the approaches involved in auditorium designs are shape, volume, surface boundary dimensions and materials, stage, seating, foyers and sightlines. These parameters are grouped under acoustical, functional and programmatic parameters. Reverberation time calculated was high which indicated speech intelligibility problems, hence, improvement efforts were made to change the floor materials from polished tiles to carpeted floors, and high absorption wall claddings. In the process, the reverberation time was reduced from 1.47 -2.23 to 0.84 -1.73 for the studied buildings. The study recommends strict adherence to standards and guidelines, and for designers to have a keen focus on designing these special buildings. A renovation effort when undertaken, will lead to improvements in the performance of the selected buildings.

“…And the report aimed to validate the finding of using the simulation software in acoustic design and prediction not to suggest alternatives materials for the hall. Elkhateeb [10] used ODEON software as a tool to design a new lecture hall at Ain Shams University, to assist the learning process for faculty of law. The room was evaluated after construction in an unoccupied state using field measurements to calculate D50, STI, L, and T o .…”

Based on the clarity of speech for educational facilities. This research was carried out on adapting the field survey to determine the architectural and acoustic measurements, followed by a digital simulation using CATT for both rooms. Sustainable treatments were provided to improve the sound environment of the learning process and were again tested using CATT. Analysis and simulation indicate that both rooms suffer from poor acoustics due to the surrounding area and the finishing materials selection. One possible solution to this problem is to use a new sustainable absorbent to maximize uptake, reducing excessive reverberation time to acceptable values, increasing early reflections and eliminating shadow areas that improve speech clarity for all receivers.

“…Other measurements indicated the uniformity of the acoustical field in the room. Elkhateeb 4 notes a problem of relatively high background noise because the designers had used natural ventilation, and this directly contradicted the principles of room isolation.…”

“…The work of Elkhateeb 4 concerning the acoustical design of the new lecture auditorium, Faculty of Law, Ain Shams University, Cairo, Egypt, studies the main acoustical design phases. It also discusses some of the architectural details used that had a direct effect on the acoustical environment within the auditorium.…”
