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 EPFL - LAI is investigating novel haptic technologies for rendering rich vibrotactile feedback in digital musical interfaces. The main objective is to develop an interactive surface that can render multitouch vibrotactile stimuli. As part of this resea ...
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 ...
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 ...
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 ...
Unreinforced masonry buildings with flexible timber floors are amongst the most vulnerable building typologies for seismic loading. Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the impact of the connect ...
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 ...
A unidirectional shake-table test was performed on the half-scale prototype of a natural stone masonry building aggregate, to investigate the seismic performance of this type of historical construction and to assess the effectiveness of two retrofit soluti ...
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 ...
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 ...
