Lung Disease Classification Based on Lung Sounds—A Review

Sounds of hearts and lungs are one of the important human physiological signals. The lungs produce noises, when you breathe in and out. These noises can be identified with a stethoscope. The noises of your breath might be normal or abnormal. Based on the noise, a disease can also be classified. This chapter explains the different ways to identify lung diseases such as chronic obstructive pulmonary disease (COPD) and pneumonia by classifying the lung sound. Initially, basic symptoms are considered to recognize pneumonia. Further, how computational intelligence in health care addressing the treatment is discussed. There are many machine learning algorithms to recognize lung diseases based on lung sounds. This chapter throws light on various classifiers for the detection of lung diseases.
