Abstract: A device for signalling acoustic signals associated to a sound source to people having hearing problems. The device includes receiving and transmitting elements, which can be associated to a specific acoustic alarm, by an appropriate phase for recording and recognizing the sound and associating to an identifying code, near the emitting sound source. The device also includes a portable terminal, apt to receive and recognize the signals emitted by the receiving and transmitting elements. The device further includes software, installed on a portable processing device capable of connecting to the wireless connection of the portable terminal of providing an interface for programming the terminal, where each receiving and transmitting element is shaped like a plate acting as transducer for the mechanical vibration and includes a fastener to a surface.

Abstract: A device for signalling audible alarms, or other specific acoustic signals associated to a respective sound source to people having hearing problems, comprises: a plurality of receiving and transmitting elements, each one can be associated to a specific acoustic alarm, by means of an appropriate phase for recording and recognizing the sound and associating to an identifying code, near the emitting sound source thereof, the receiving and transmitting element comprising: a piezoelectric sensor for receiving the acoustic alarm; a microprocessor provided with at least a storage device, implementing the recognition of the acoustic alarm by means of FFT analysis; and means for the radiofrequency transmission of a signal thereto the code identifying the receiving and transmitting element is associated; a portable terminal, apt to receive and recognize the signals emitted by the receiving and transmitting elements, having: a radiofrequency antenna, a processor associated to a storage device including a library of cod
