Abstract: Medical apparatus (20) includes an auscultation pickup unit (26) configured to sense acoustic waves emitted from a body of a subject (24) and to output signals in response thereto. Processing circuitry (40, 42, 44, 50) is configured to collect the signals output while the auscultation pickup unit contacts multiple locations on the body of the subject, including a respective signal acquired at each contacted location, to extract from each of the signals features of breath sounds of the subject, to compute multiple local scores including a respective local score for each contacted location based on the features extracted from the respective signal, and to classify a respiratory condition of the subject by combining the multiple local scores.

Abstract: An apparatus is used to detect insect infestations within a tree. The apparatus is used to insert a needle of a microphone housing within the tree. The microphone housing includes a microphone coupled to the needle. The microphone monitors an audio window. Within the audio window a plurality of overlapping audio sub-windows are detected. A mel spectrogram is calculated from the plurality of overlapping audio sub-windows where the mel spectrogram includes a matrix of features. A neural network determines if each of the plurality of overlapping sub-audio windows includes an indication of an insect being present and determines if the indications of an insect being present of the plurality of overlapping audio sub-windows indicates that the tree has an insect infestation.

Abstract: Embodiments of the invention determine a speech estimate using a bone conduction sensor or accelerometer, without employing voice activity detection gating of speech estimation. Speech estimation is based either exclusively on the bone conduction signal, or is performed in combination with a microphone signal. The speech estimate is then used to condition an output signal of the microphone. There are multiple use cases for speech processing in audio devices.

Abstract: An acoustic-to-electrical transducer (152) for sensing body sounds is disclosed. The transducer (152) comprises a diaphragm (2/202) that can be placed in direct contact with a body, whereby the diaphragm motion directly affects an electromagnetic sensing signal, which is then converted to an electrical signal representation of the diaphragm motion. Such sensing means (70) allows the diaphragm (2/202) to move freely without mechanical coupling to a secondary transducer, while providing a direct and further provides a means for using static diaphragm pressure to control gain and frequency characteristics of the electrical signal. The transducer provides methods for ambient noise reduction or applications such as well as means for simulating sound detection for applications such as medical education and testing. The sensor, circuitry, manufacturing methods and improvements are disclosed.
