Aim: To enable the students to optimise desired vibrations and minimise indesirable vibrations in practical structures, and as a part here of minimise acoustic noise. This requires an understanding of modality and natural frequencies, together with the ability to judge the effectiveness of different damping devices.

|
Contents: Systems with one and two degrees of freedom. Vibration isolation. Continuous beams. Response for undamped and damped systems. Transfer function. Natural frequency and normal modes. Noise measurement, reverberation measurement, room acoustics, sound power measurement, principles of noise damping. Laboratory exercise in vibration and acoustic measurements.
