This study proposes the Mathematical Formula for Systematic Digestive Sounds (MFSDS), a method that converts abdominal audio signals into mathematical formulas for automated analysis. The approach integrates devices from the Internet of Things (IoT), signal processing, and artificial intelligence to address challenges such as acoustic complexity, environmental noise, and individual variability. Experimental evaluation with datasets of 25, 50, and 100 formulas achieved similarity rates between 50% and 67%, indicating potential for improvement. Although initial accuracy remains below clinical application thresholds, the results suggest that the integration of advanced AI techniques could improve precision and adaptability. The MFSDS framework offers a novel perspective for preventive healthcare and real-time gastrointestinal monitoring.<\/jats:p>","DOI":"10.3897\/jucs.160360","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T10:20:19Z","timestamp":1779358819000},"page":"736-760","source":"Crossref","is-referenced-by-count":0,"title":["Toward a Mathematical Approach to Sound Waves for&amp;nbsp;Enhancing Digestive Health"],"prefix":"10.3897","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-3923-1450","authenticated-orcid":true,"given":"Kevin","family":"Lima","sequence":"first","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0312-1310","authenticated-orcid":true,"given":"Alex","family":"Roehrs","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3859-6199","authenticated-orcid":true,"given":"Cristiano","family":"Andr\u00e9 da Costa","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5080-7660","authenticated-orcid":true,"given":"Rodrigo da Rosa","family":"Righi","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0358-2056","authenticated-orcid":true,"given":"Jorge Luis Vict\u00f3ria","family":"Barbosa","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1891-3580","authenticated-orcid":true,"given":"Kleinner Silva Farias","family":"de Oliveira","sequence":"additional","affiliation":[{"name":"University of Vale do Rio dos Sinos, S\u00e3o Leopoldo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2026,5,28]]},"container-title":["JUCS - Journal of Universal Computer Science"],"original-title":[],"link":[{"URL":"https:\/\/lib.jucs.org\/article\/160360\/download\/pdf\/","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lib.jucs.org\/article\/160360\/download\/xml\/","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lib.jucs.org\/article\/160360\/download\/pdf\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T10:20:19Z","timestamp":1779358819000},"score":1,"resource":{"primary":{"URL":"https:\/\/lib.jucs.org\/article\/160360\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,28]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2026,5,28]]}},"URL":"https:\/\/doi.org\/10.3897\/jucs.160360","relation":{},"ISSN":["0948-6968","0948-695X"],"issn-type":[{"value":"0948-6968","type":"electronic"},{"value":"0948-695X","type":"print"}],"subject":[],"published":{"date-parts":[[2026,5,28]]}}}
