摘要： The present invention relates to a device for auscultation of a body. An embodiment of the device includes a housing dimensioned and configured for disposition in an operative orientation relative to a predetermined portion of the body. The housing includes a plurality of chambers disposed therewithin. The plurality of chambers are collectively structured to receive an acoustic signal at least when the housing is disposed in the operative orientation. The housing also includes at least one transducer at least partially disposed in a corresponding one of the chambers. The transducer is structured to convert the acoustic signal into an electrical signal. A concentric structure is formed around the housing for additionally receiving and processing low frequency signals.

摘要： The present invention provides for systems and methods for acquiring acoustic information from a resonating body. Specifically, a focused light beam is emitted from an emitter module onto an impedance matching reflector. The impedance matching reflector has similar wave propagation characteristics to the resonating body, so as to capture a mechanical vibrations thereof. The impedance matching reflector reflects the focused light beam as it vibrates, and the vibrations are captured by a receiver module through the reflected light beam, which is converted to an input signal. The input signal may be further processed and converted to an audio output signal, as an accurate representation of the acoustic information emanating from within the resonating body.
