Title Study of the acoustic behaviour of sound-absorbing materials for possible use in the food industry
Original title Etude du comportement acoustique des matériaux absorbants susceptibles d'être utilisés dans l'industrie alimentaire [in French]

Abstract Hygiene constraints in the food industry limit the choice of conventional sound-absorbing materials that can be used. Models potentially usable in the food industry were identified and subject to theoretical and experimental study. A computer model of the acoustic behaviour of the materials available on the market was developed, and their absorption coefficients were measured. The model was validated by comparing the values measured with those calculated. It was then used to determine how the absorption coefficient changed with an air space behind the material. Finally, a noise prediction study demonstrated the usefulness of these materials, applied only to the ceiling, in reducing reverberation at the workplace when reverberation by the walls made a significant contribution to the workplace noise level.
