© 2017 Institute of Noise Control Engineering. All rights reserved. The Faculty of Engineering and Information Technology at the University of Technology Sydney has a noise control subject offered to final year engineering students and postgraduate coursework students as an elective. The subject assumes little pre noise control knowledge and teaches fundamental acoustic concepts. The acoustic box experiment was designed to expose the student to many acoustics concepts such as absorption, attenuation, and measurement at different distances from a sound source. The acoustic box can be configured it a variety of configurations to demonstrate many acoustic concepts such as the effect of small openings and attenuation when the sound propagates along different shaped absorptive path ways. The magnitude, frequency and waveform of the sound source can be varied for each cohort of students to reduce plagiarism. The use of the acoustic box has proven successful in reinforcing and allowing the students to learn fundamental acoustic principles by observation.
