نویسنده
چکیده
Looking at the increasing request concerning sound insulation in building, TechnoFirst@ and Saint Gobain Vitrage propose an active double-glazing window. In this partnership, TechnoFirst@ brings its experience in active control system. The product will be characterized by a global insulation never obtained. It deals with an acoustic treatment of the air volume. Modelisations have been done and show the contribution of each acoustic mode. The experiments have confirmed these information. This publication shows first results obtained with a prototype. The control process is also presented. The electroacoustic system which allows this treatment can be fitted into the width of the air volume and is distributedto the four sides of the window.

This paper presents an investigation into the development of an active vibration control (AVC) system using genetic algorithms (GAs). During the last two decades, a substantial amount of research work has been carried out using GAs in various disciplines. Although GAs have gained popularity as parallel, global search techniques, their use in the area of active control is limited. This investiga...

Electro-Optic Holography (EOH) is a laser based, fill field diagnostic technique used to measure micron sized deflections in statically displaced or vibrating structures. When applied to dynamically excited objects, EOH yields the time averaged displacement profile of the object surface. To obtain the structural power flow from EOH measurements, the structural phase must be extracted. This pape...

The aim of this paper is firstly to address the consequences of the nonlinear interactions between higher order modes and the first order mode of a flexible cantilever beam. The tested cantilever beam exhibited numerous nonlinear phenomena that are commonly observed in many flexible structures. The experimental results have shown that active control of the nonlinear vibration in a flexible stru...

Active noise control technology is an attractive solution for attenuation of low frequency noise in enclosures. In terms of control strategies, feedforward control has often been used. While feedforward control has many advantages, its success relies on the availability of causal reference signals which have to be highly correlated to the noise to be cancelled. For some applications such as att...

This paper describes a new method estimating an objective low-frequency acoustic sound contaminated with wind noise in the outdoor measurement. It is a dynamic estimation technique employing a reference band pressure level (BPL) of a particular frequency range of the observation as the basis of the wind noise estimation. First, a conditional probability distribution function (c.d.f) of the wind...
