Diagnosis of lung sound using the stethoscope has the many limitation. It depends on the experience and skill of the medical practitioners. Lung sound classification has two parts, first is the feature extraction and second is the classifier used for the classification. Here a biomedical based system is proposed for the feature extraction of lung sound which is done using daubechies wavelet (db10). The features which have been extracted are energy, entropy, standard deviation and variance of the normal lung sound (e.g. vesicular.) and adventitious lung sounds (e.g. crackles and wheezes) and a comparative study has been given between the various features of lung sounds.
