Abstract
A support pad for use in a hearing device of the type comprising a casing having an inner surface defining a cavity; and a sound receiving, amplification and transmitting system within the cavity in the casing, which system includes a transducer. The support pad includes a layer of conformable metal having first and second opposite major surfaces, and a layer of viscoelastic material along its first major surface. The support pad has an attachment portion with the layer of viscoelastic material along the attachment portion being adapted to be adhered to a side surface of the transducer, and has at least one tab portion adapted to project away from the transducer adjacent an end of the transducer. The tab portion is adapted to be shaped so that the second major surface along the tab portion is adjacent and conforms to the inner surface of the casing and can be adhered to the inner surface of the casing with the tab portion shaped and positioned so that the attachment portion of the support pad and the transducer are spaced from the inner surface of the casing.
