Abstract

See full text

A speech transmission adapter and a respirator mask comprising a speech transmission adapter. The respirator mask comprises an inhalation port, an exhalation port, and a speech transmission adapter in detachably sealed engagement with the inhalation port. The adapter comprises a peripheral housing, a speech reception means supported by the peripheral housing, and a speech transmission means operably coupled to the speech reception means. The speech reception means receives sound pressure generated by a wearer of the respirator mask, and the speech transmission means conveys signals representative of such sound pressure to an external speech transducer. The adapter mates to the inhalation port of a respirator mask and expands the clean air envelope defined within the mask to include the speech reception means within the clean air envelope without requiring structural modification of the respirator mask. The speech transmission adapter comprises a central aperture which is adapted to accommodate the passage of air therethrough and engaging means at each of its ends.
