Abstract:

The work involved the design of an experimental ceramic piezoelectric gradient microphone of particular promise for use in diving masks and undersea habitats from sea level to deep submergence, and the discovery and demonstration that speech intelligibility is insensitive to mask cavity size and shape, in both air and helium, when this microphone is used.
