Integrated Active Noise Control and Noise Reduction in Hearing Aids KU Leuven
Active sound field and noise control in wireless acoustic transducer networks KU Leuven
The active control of sound fields using microphone and loudspeaker arrays has been an active research topic for many decades, with applications in noise control, sound zoning, etc. This PhD project aims to address the active sound field control problem in a context of wireless acoustic transducer networks, in which microphones, loudspeakers, and computational resources are spatially distributed and in-network wireless communication is ...
Bridging the gap between architecture/city planning and urban noise control Ghent University
The research intends to improve the city sound environment at street level, by bridging the gap between city planning and urban noise control measures. It has been shown that street canyon design can strongly impact direct exposure along walkways and facades. Audio-visual interactions are explored and exploited in the urban environment to achieve holistic noise reduction. (56)
Active reduction of noise transmitted into and from enclosures through encapsulated structures KU Leuven
To better reduce exposure of people to noise and increase their acoustic comfort, innovative noise barriers should be developed. The overarching aim of IN-NOVA is to provide a top-level training for 10 Doctoral Candidates (DC) - MSCA Fellows plus 3 DCs funded by UK (supervised by UCL - 1 DC and UOS - 2DCs), in a wide variety of cutting-edge noise control technologies, developing a new generation of creative and entrepreneurial innovators. The ...
IN-NOVA-MSCA-DN-2021 "Passive and active approaches for noise reduction in automotive applications" Grant agreement ID: 101073037 KU Leuven
This project targets noise reduction of Hybrid-electric vehicles (HEVs). HEVs and battery-electric vehicles (BEVs) are cleaner and produce less exterior noise than cars with internal combustion engines. However, the interior noise is characterized by high-frequency noise components which can be subjectively perceived as annoying and unpleasant. The challenge is to reduce the interior noise levels in (H/B)EV, without adding too much weight to ...
Component Based TPA for Virtual Vehicle Noise and Vibration Prediction KU Leuven
The goal of the PhD will be to develop and validate an hybrid engineering technique that allows quantifying the contribution of vehicle subsystem components early in the design. This will be achieved by combining source component models obtained from test bench measurements with vehicle noise transfer functions coming from both test and numerical simulations. By doing so, the effects of engine control settings and vehicle design changes can ...
Smart mitigation of flow-induced acoustic radiation and transmission for reduced aircraft, surface transport, workplaces and wind energy noise KU Leuven
A step change in our noise mitigation strategies is required in order to meet the environmental targets set for a number of sectors of activity affecting people through noise exposure. Besides being a hindrance to our daily life and subject to regulations, noise emission is also a competitive issue in today’s global market. To address these issues, new technologies have been emerging recently, based on radically new concepts for flow and ...
Design Strategies for Narrow and Broadband Noise and Vibration Reduction through Distributed Resonators KU Leuven
Environmental as well as ecological requirements combined with the drive for efficiency have given rise to the introduction of lightweight designs. Nonetheless, their resultant increased stiffness-to-mass ratio often leads to a poor noise and vibration insulation performance. Given the well-known shortcomings of classical noise control measures, thus, their mass and/or volume, novel solutions are pursued. In this context, distributed ...
