Patent abstract
An acoustic-electronic stethoscope that filters aberrant environmental background noise. The chest piece employs acoustic vents to inhibit resonant amplification of noise and contains a diaphragm design that focuses vibrational energy to a raised ring, which transfers and further focuses the energy to a piezoelectric polymer sensor with dual elements. The ensuing electrical signal is then preamplified with the low frequency sound, comprising predominantly background noise, filtered out. The stethoscope contains a binaural head set and output jack for down loading of data. Furthermore, areas normally subject to exposure and damage to water, such as the chest piece and headset, are water-tight.
