We investigated the potential distances over which female dolphins and their dependent calves could remain in acoustic contact. We quantified the propagation of sounds in the frequency range of typical dolphin whistles in shallow water areas and channels of Sarasota Bay, Florida. Our results indicated that detection range was noise limited as opposed to being limited by hearing sensitivity. Sounds were attenuated to a greater extent in areas with seagrass than any other habitat. Estimates of active space of whistles showed that in seagrass shallow water areas, low-frequency whistles (7\u201313kHz) with a 165dB source level could be heard by dolphins at 487m. In shallow areas with a mud bottom, all whistle frequency components of the same whistle could be heard by dolphins travel up to 2km. In channels, high-frequency whistles (13\u201319kHz) could be detectable potentially over a much longer distance (&amp;gt;20km). Our findings indicate that the communication range of social sounds likely exceeds the mean separation distances between females and their calves. Ecological pressures might play an important role in determining the separation distances within communication range.<\/jats:p>","DOI":"10.1121\/1.2226559","type":"journal-article","created":{"date-parts":[[2006,9,11]],"date-time":"2006-09-11T19:04:37Z","timestamp":1158001477000},"page":"1671-1683","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":57,"title":["Estimated communication range of social sounds used by bottlenose dolphins (<i>Tursiops truncatus<\/i>)"],"prefix":"10.1121","volume":"120","author":[{"given":"Ester","family":"Quintana-Rizzo","sequence":"first","affiliation":[{"name":"University of South Florida College of Marine Science, , 140 7th Avenue South, St. Petersburg, Florida 33701"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Mann","sequence":"additional","affiliation":[{"name":"University of South Florida College of Marine Science, , 140 7th Avenue South, St. Petersburg, Florida 33701"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall S.","family":"Wells","sequence":"additional","affiliation":[{"name":"c\/o Mote Marine Laboratory Chicago Zoological Society, , 1600 Ken Thompson Parkway, Sarasota, Florida 34236"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023073108344917200_c1","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1163\/156853974X00534","article-title":"Observational study of behavior: Sampling methods","volume":"49","year":"1974","journal-title":"Behaviour"},{"key":"2023073108344917200_c2","first-page":"511","article-title":"The active space of Red-winged Blackbird song","volume":"142","year":"1982","journal-title":"J.
