Representation of the results is performed according to both methodological and applicative taxonomies. The study method covers a wide span of related keywords using well-known search engines. Implementation of the observed methods along with the related results is pervasively represented and compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results and discussion<\/jats:title><jats:p>It is observed that convolutional neural networks and recurrent neural networks are the most commonly used ones for discriminating abnormal heart sounds and localization of heart sounds with 67.97% and 33.33% of the related papers, respectively. The convolutional neural network and the autoencoder network show a perfect accuracy of 100% in the case studies on the classification of abnormal from normal heart sounds. Nevertheless, this superiority against other methods with lower accuracy is not conclusive due to the inconsistency in evaluation.<\/jats:p><\/jats:sec>","DOI":"10.3389\/frai.2024.1434022","type":"journal-article","created":{"date-parts":[[2024,11,13]],"date-time":"2024-11-13T11:41:00Z","timestamp":1731498060000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":30,"title":["A review on deep learning methods for heart sound signal analysis"],"prefix":"10.3389","volume":"7","author":[{"given":"Elaheh","family":"Partovi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ankica","family":"Babic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arash","family":"Gharehbaghi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,11,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"183","DOI":"10.9734\/jpri\/2021\/v33i47B33112","article-title":"A systematic review on machine learning and deep learning based predictive models for health informatics","volume":"33","author":"Abdullah Aloyuni","year":"2021","journal-title":"J.
