    Abstract - (Show below) - (Hide below)

    Describes methods for the measurement under laboratory conditions of airborne and structure borne sound produced by whirlpool baths connected to low mobility structures; for the case of whirlpool baths, building structures of mass per unit area equal or greater than 220 kg/m[2], hollow elements excluded, are considered as low mobility elements.
