On peut soit fabriquer séparément les corps amortisseurs et les plaques céramiques puis les réunis* de manière amovible ou les coller par un adhésif approprié, ou bien on introduit, lors de la confection de la plaque, dans les @ trous de celle-ci, le matériau du corps amortisseur, par exemple les petits tubes disposés parallèlement les uns aux autres et on réalise la liaison des éléments du corps amortisseur entre eux et avec la plaque,
à l'aide d'une cuisson à grand tout
Les plaques qui, généralement, sont carrées et ont entre 10 et 20 cm de coté, peuvent être apposées de la manière habi- tuelle sur une construction de force portante suffisante (par exemple une ossature),qui fixe la distance entre la plaque et le mur ou le plafond.

Par ces trous l'eau de nettoyage pénétrant dans la cavité peut s'écouler en entraînant: les saletés.
On doit tenir compte de ces ouvertures lors de la détermination de la résonnance du dispositif,
Dans les endroits où le revêtement est exposé à de fortes souillures, s'indiquent les plaques avec corps amortis- seurs amovibles* Les pores obturés de telle garniture peuvent être dégagea par lavage des un liquide de nettoyage.

The plates which are generally square and have a side between 10 and 20 cm, can be affixed in the usual way on a construction of sufficient load-bearing strength (for example a framework), which fixes the distance between the plate and the wall or ceiling. This distance from the wall which, as mentioned is, next to other quantities, of importance

essential for the resonance frequency, is between about 5 to 3o ara. The air mattress between the plate and the wall or ceiling can be cut, in a horizontal and vertical direction, by strips of non-porous material (eg masonite), placed at the joints of all two or three places.
In order to dispense with the placement of the framework in the case of small distances between plate and wall, one can apply by casting, on the perimeter of the plate and perpendicular.

Through these holes the cleaning water entering the cavity can flow out, entraining: dirt.
These openings must be taken into account when determining the resonance of the device,
In places where the covering is exposed to strong soiling, the plates with removable shock-absorbing bodies are indicated. The pores blocked by such a lining can be freed by washing out a cleaning liquid. This formula is particularly advantageous when the covering of walls or ceilings is designed for a narrow strip of

frequencies, because then the soiling could act particularly strongly on the resonant frequency and on the damping.
In the interest of low labor consumption when cleaning such plates, the number of damping elements of each plate should be chosen as low as possible.
