Abstract

Prevention of transmission of sound and conversion of sound energy to non-audible form are the function of acoustical materials. As a ray of sound undergo several reflections of bouncing forth and back within a space, the energy lost at each reflection eventually dismisses the ray. Sound and vibration sources are usually speech, music, mechanical equipment and traffic. Absorption, reflection and transmission of sound occur during sound transmission in a building due to the nature of the building materials and furnishings. Sound absorbing materials such as mineral wool or glass wool are usually light weight, porous, consist of matrix of fibers with interconnecting pores and capillaries. This study was designed to identify design features and elements that can improve sound quality, noise control, and reduce echoes and reverberation in the convention centre facility located in Rumuoda, Aluu, Port Harcourt, Rivers State, Nigeria. The author adopted a mix research method which includes qualitative and quantitative techniques for the collected data. Various operational convention centers were selected as case studies. The criteria for case study selection include; Architectural merits, adequate planning of the facilities, building materials used, design elements and features used. The deduction from the entire study assisted in the design of the convention centre, which are design elements that help absorb sound energy; walls, ceiling, and floors, design features; acoustic panels, upholstered chairs, soft porous surfaces, carpets, solid core doors, fiber glass, acoustic tiles, curtains. Also, size and shape of a space (auditorium) , seating arrangement, audience capacity, materials in the room , balcony are generally factors that affects the acoustics of an auditorium. In conclusion, the use of appropriate design elements and features which can absorb sound energy in an auditorium will help improve sound quality, noise control, and reduce echoes and reverberations in the facility. Therefore, it is essential that Architects and Builders put into consideration on how to improve sound quality, control noise, and reduce echoes and reverberations, to achieve sound clarity, for the comfort of the seated audience.
