Environmental noise, mostly related to human activities, has an immense impact on public health. The development of noise reduction technologies is paramount in addressing this problem. Because of practical and economic reasons, a compact, broadband, light ...
Invented at the end of the XIXth century, the electrodynamic loudspeaker has not much changed sincethen. Although the materials have greatly evolved, the geometry and the transduction principle staythe same. In many applications, the presence of two sets o ...
The recent introduction of acoustic metamaterials and metasurfaces in the literature has triggered an tremendous interest in the scientific community, with their capability to achieve extraordinary acoustic properties for various acoustic and noise control ...
Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the effect of the connections between floors and walls is rarely discussed or explicitly modelled when simulating the response of such buildings. These flexi ...
Some of the most important and challenging problems in science are inverse problems. They allow us to understand phenomena that cannot be measured directly. Inverse problems might not always have a unique or stable solution, or might not have any solution ...
Air traffic noise emissions are responsible for a significant part of the overall environmental noise, especially in the vicinity of airports. Exposure to environmental noise is known to negatively impact health and to be associated with cardiovascular dis ...
The extensive deployment of non-synchronous generation determines lower level of grid inertia resulting in deteriorated frequency containment performance and abnormal frequency excursions in case of contingency. This calls for identifying assets, controls, ...
The seismic in-plane response of cold-formed steel (CFS) framed diaphragm structures has not been the subject of extensive study. The information available specific to diaphragm design in the North American CFS design standard is based on limited experimen ...

This paper describes a research program involving wood-sheathed and cold-formed steel (CFS) framed diaphragm assemblies.The diaphragm’s response to in-plane monotonic and reversed cyclic lateral loading is investigated in an effort to characterize the seis ...
This paper presents a concept of sensorless electroacoustic absorber for damping the low-frequency modes in a cavity such as a duct or a room. Taking advantage of the reciprocity of the voice coil transducer, it is shown that a synthetic electrical admitta ...
