Transducer apparatus for high speech intelligibility in noisy environments

A transducer apparatus comprising a transducer, wherein

• the transducer is an acoustical microphone adapted to sense vibrations arising from the user's voiced and unvoiced sounds,
• the acoustical microphone having a housing,
• the housing having a hole that serves as the acoustical input port,
• the adaption of the acoustical microphone to sense vibrations is by means of the hole being placed on or pressed against the non-boney and non-cartilaginous part of said user's head,
• the non-boney and non-cartilaginous part of the user's head is the fleshy area of the user's cheek near the mouth of the user or the fleshy area under the user's chin, and
• the vibrations include that arising from the user's speech are conducted to the surface of the fleshy area of the user's cheek through the flesh of the user's cheek or the surface of the fleshy area under the user's chin through the flesh of the user's chin.
