- W2801441639 abstract "Most of the auscultation sounds do not reveal any significant single-frequency components, and their acoustic energy is concentrated in the low frequency region—up to about 100 Hz, falling even below the threshold of hearing. Such character is determined not only by the vibroacoustic behavior of sources, but mostly by high damping introduced by the sound transmission path through tissues underlying the skin surface. The contained diagnostic information is very subtle, and thus it can be easily masked by internal or external noise sources. Not all of those corrupting signals can be efficiently blocked, hence frequency filtering is the most obvious solution for improving the diagnostic capabilities. Many various filtering strategies and techniques were developed and implemented in both acoustic and electronic stethoscopes, however they are based primarily on (not always correct) intuition and subjective evaluation, without implementation of any accurate and objective measurement means or optimization algorithms. The present study introduces various signal to noise ratio (SNR) measures, applicable for different examination cases. Frequency filtering optimization strategies, for maximizing the values of the introduced coefficients for different heart and lung auscultation sounds, are presented." @default.
