Active control of noise in ventilation ducts
( Canadian Acoustical Association , 2019 , Conference Paper)Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ... -

Experimental detection of localized surface defects in ball bearings using vibration analysis
( Canadian Acoustical Association , 2019 , Conference Paper)This study aimed at the monitoring of bearing health condition, based on vibration measurement. For that purpose, small circular defects were seeded on outer and inner rings of similar bearings, by using the principle of ...
