Development of an active noise control earplug
( International Institute of Acoustics and Vibration, IIAV , 2018 , Conference Paper)Active Noise Control (ANC) is used in controlling low frequency noise where passive control is ineffective. This paper presents the main results obtained from the development of an active noise control earplug for use in ... -
Effect of high pass filtering of the regenerated reference signal in a single channel active noise control system
( International Institute of Acoustics and Vibration, IIAV , 2018 , Conference Paper)An acoustic noise cancellation (ANC) system with regenerative feedback synthesizes its own reference signal based on the error signal and the adaptive filter output. The prime objective of such a configuration is to estimate ... -
Effect of reflective surface on the impulse response of the secondary path of an active noise control system
( International Institute of Acoustics and Vibration, IIAV , 2018 , Conference Paper)Previous research has shown that a reflective surface has an impact on the control performance of an active noise control system. System identification of the secondary path is of utmost importance in the effectiveness of ... -
Numerical simulation of one-stage gearbox dynamics in the presence of simultaneous tooth cracks
( International Institute of Acoustics and Vibration, IIAV , 2017 , Conference Paper)Gears are vital components in various industrial machinery. Tooth fatigue crack is amongst the most common causes of gear failure. Early detection of tooth cracks is crucial for effective con-dition-based monitoring. This ...
