The general aim of this thesis has been to demonstrate how noise could be reduced at the design and development stages of industrial machinery by effective engineering design. Part A embodies the general methods of noise generation mechanism and principles of noise control. The case studies having entirely contrasting noise problems are presented in Parts B and C, where advanced experimental techniques such as dynamic strain measurement, hologram interferometry and high-speed photography have been used for analysis purposes. The first case study is made on a textile machinery drawroll assembly (Part B) in which a drawroll radiates much of the noise at a single frequency. The drawroll is reciprocated by the fundamental longitudinal mode of vibration of the assembly which is excited by small impactive but random forces at its gear drive.
