Computerized Lung Sound Screening for Pediatric Auscultation in Noisy Field Environments

Clinical auscultation in noisy environments.

Smartphone-Based Hearing Screening in Noisy Environments

It is important and recommended to detect hearing loss as soon as possible. If it is found early, proper treatment may help improve hearing and reduce the negative consequences of hearing loss. In this study, we developed smartphone-based hearing screening methods that can ubiquitously test hearing. However, environmental noise generally results in the loss of ear sensitivity, which causes a he...

Performance evaluation and enhancement of lung sound recognition system in two real noisy environments

This study investigates the problems associated with lung sound recognition under noisy conditions. Firstly, the effects of noise on the lung sound feature representation and the classification performance are analyzed. Two kinds of feature representations, autoregressive and mel-frequency cepstral coefficients, are used to characterize the lung sound signals. Dynamic time warping is used to ca...

Fundamentals of lung auscultation.

Chest auscultation has long been considered a useful part of the physical examination, going back to the time of Hippocrates. However, it did not become a widespread practice until the invention of the stethoscope by René Laënnec in 1816, which made the practice convenient and hygienic.1 During the second half of the 20th century, technological advances in ultrasonography, radiographic computed...

Clinical auscultation skills in pediatric residents.

OBJECTIVE The aim of this study is to determine the level of clinical auscultation skills in pediatric residents at Duke University Medical Center. METHODS Forty-seven residents from pediatrics and joint medicine/pediatrics training programs at Duke University Medical Center were enrolled in this study. They were asked to examine the cardiovascular patient simulator, Harvey, and report their ...
