Abstract (en)
The device for transducing noise generated inside a body, in particular for transducing voice, for the detection outside of the body with a great damping of environmental noise consists essentially of a sheet element operating as a transducer associated with a supporting body adapted to provide a pressure between said sheet element and a contact surface forming a portion of the noise generating body so as to not transduce directly the noise as an acoustic phenomenon through the air but as a vibration affecting said contact surface and generated by the noise itself.
