Sound Design of a technical object - proposal for a technical and sensitive approach
Résumé
This paper describes a collaboration, in 1995, between the CRESSON and the CERG (Research and Survey Center : ACB - GEC - ALSTHOM), in Grenoble (France). The CERG, expert in industrial acoustic, vibration, mecanic and outflow, has understood that the "decibels run" is reaching its limits, and that manufacturers won't spend more time and more funds to reduce noise of sonic bjects. Even though work has be done, electric engines or computer fans, for exemple, will still be noisy for some time.
Therefore, another approach can be considered, which may interest manufacturers, which aims to modify, to change, in a word, the sound design of technical object.
My work was to conduct two sonic approaches at the same time : one, acoustic, based on measurements, and the other one, ecological, based on perception of sound in situ. This work was essentially theorical, we didn't have enough time to pratice the results of the survey.
I attempted to go beyond classical studies which correlate subjective evaluation with acoustic parameters. Consequently, my purpose was to begin a sound design project, that is to say, bring to light the role of sound in the construction of our relationship with technical objets : what is the meaning of the sound of an object ? Is the sound well correlated to the use of this bject ? How does the sound create, in the user's perception, a good or a bad evaluation ?
