Abstract：Objective To construct a model with a spatial and channel reconstruction convolutional module for accurate identification and classification of lung sound data.Method We propose a convolutional network architecture combining the spatial-channel reconstruction convolution(SCConv)module.A lung sound feature extraction method combining the dual tunable Q-factor wavelet transform(DTQWT)with the triple Wigner-Ville transform(WVT)was used to improve the model's ability to capture the key features of the lung sounds by adaptively focusing on the important channel and spatial features.The performance of the model for classification of normal,crackles,wheezes,and crackles with wheezes was tested using the ICBHI2017 dataset.Results and Conclusion The accuracy,sensitivity,specificity and F1 score of the proposed method reached 85.68%,93.55%,86.79%and 90.51%,respectively,demonstrating its good performance in classification tasks in the ICBHI2017 lung sound database,especially for distinguishing normal from abnormal lung sounds.
