Abstract

The final year project is a requisite subject for engineering students towards completing the Bachelor Degree program. The final year project is exposed to observe students what they have learned in four years at university, thus relates the theoretical and technical knowledge with the relevance in the final year project. Right through the final year project, students were projected to successfully enhancing their skills in technical, communication, management time, creativity as well as able to give personal ideas or opinions. For a mosque in UTeM, the acoustical requirements in terms of intelligibility and liveliness are dissimilar for the types of sounds-recitation and speech on religious subjects. To attain an overall satisfactory acoustical performance, it is significant to find an optimum Reverberation Time (RT) and the best directivity, which is the major factors affecting intelligibility and liveliness. Experiment is conducted to find the effect of RT by making it a variable, while keeping other factors as non-variable and fulfilling ideal conditions for maximum intelligibility. Bearing in mind, the acoustical problems always occurred in acoustical building. To improve the problem, this researched is come out with the new idea of solution by using biodegradable sound absorber materials which is the mixture of Dried Rice Straw and Kekabu. All the outputs is represent by using DPlot Simulation.
