Acoustic holography techniques for characterizing noisy industrial machinery C.1/1.062 | 2011

Outline of reasons and objectives
Acoustic holography is a technique that makes it possible to map the acoustic field at the surface of a noisy mechanical system on the basis of measurements taken in a parallel plane situated a small distance…

CIBNAH: a new Near-field Acoustic Holography method with no requirement for reference signals. C.1/1.062/C2014-119 | 2014

One of the main difficulties, in the application of Near-field acoustic holography (NAH) to noise radiating structures, is the choice of the reference signal(s). To successfully select such signals, a preliminary knowledge of the noise sources and…
Reference-less acoustic holography techniques based on sound intensity. C.1/1.062/P2013-104 | 2014

This paper describes a detailed implementation and application of an intensity based holography method called BAHIM, and investigates its possibilities and its limitations. Although this method is attractive in the sense that it bypasses…
On the performance of a hybrid (intensity – MISO) method to identify and locate noise sources in a wood processing centre. A.5/2.050/P2013-215 | 2014

An array composed of 16 intensity probes has been applied to a complex CNC wood machining centre to identify and locate the principal noise sources. The initial investigations have suggested a significant radiation from the moving head panels…
Noise abatement in wood-machines? Must first be able to detect and rank the sources! C.1/1.062/P2014-160 | 2014

Work related deafness is one of the most frequent pathologies in France. Machinery noise in work places is the principle source of the risk for deafness. In this paper, dealing with wood conditioning machines, we show that noise control procedures…
