Inspiratory and expiratory vesicular breath sounds.
TLDR
It is concluded that the lack of significant differences suggests similar mechanisms and sites of production of inspiratory and expiratory vesicular breath sounds, as well as three methods of heart sound cancellation, are suggested.Abstract:
Unfiltered breath sounds (NF) from the apical area of the heart, lung volume and ECG signals were recorded in 5 normal subjects. The signals were digitized and subjected to three methods of heart sounread more

Dynamic visualization of lung sounds with a vibration response device: a case series.
TL;DR: A new computer-assisted lung sound imaging system, ‘vibration response imaging’ (VRI), that records and creates a dynamic image and quantitative assessment of breath sound distribution is evaluated to provide a new perspective in acoustic imaging and quantification of breath sounds by adding aspects of time analysis and quantifiers to existing methods.

Qualitative and quantitative evaluation of heart sound reduction from lung sound recordings
TL;DR: Recursive least squares (RLS) adaptive noise cancellation (ANC) and wavelet transform (WT) ANC have been applied and compared for heart sound (HS) reduction from lung sounds (LS) recordings.

Characteristics of normal lung sounds after adaptive filtering.
TL;DR: The results indicated that by filtering out low frequency heart sounds, the frequency spectrum of lung sounds was moved upward.(ABSTRACT TRUNCATED AT 250 WORDS)
