Lin stumbled upon <a href=\"https:\/\/web.archive.org\/web\/20141006113229\/http:\/\/www.hopkinsmedicine.org\/FAE\/DBWpdf\/R3_1981aWeishampel.pdf\">a 1981 paper<\/a> by David Weishampel expanding on the notion, predicting that the dinosaur&#8217;s calls would have fallen in the frequency range of 55 to 720 Hertz. Weishampel&#8217;s model treated the crest as an open pipe\/closed pipe system. Lin did a bit more research, and a <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3807589\/\">2013 paper<\/a> convinced him that Weishampel&#8217;s model was due for an update.<\/p>\n<p>Lin created a physical setup to empirically test his own mathematical model of what might be happening acoustically inside <em>Parasaurolophus<\/em>&#8216; crest, dubbed the &#8220;Linophone,&#8221; although it is not a perfect anatomical replica of the dinosaur&#8217;s crest. The setup consisted of two connected open pipes designed to mimic the vibrations of vocal cords. Lin conducted frequency sweeps using a speaker to generate the sounds and recorded the resonance data with microphones at three different locations. An oscilloscope transferred that data back to his computer.<\/p>\n<p>He found that the crest did indeed seem to be useful for resonance, similar to the crests in modern birds. &#8220;If I were to guess what this dinosaur sounded like, it would be a brass instrument like a huge trumpet or saxophone,&#8221; said Lin, based on the simple pipe-like structure of his model. However, the presence of soft tissue-like vocal cords could mean that the sound was closer to that of a clarinet.<\/p>\n<p>Lin is still refining his mathematical model, and he thinks he should be able to extend it to studying other creatures with similar vocal structures.&#8221;Once we have a working model, we&#8217;ll move toward using fossil scans&#8221; to further improve it, Lin said, although he noted that one challenge is that soft tissue like vocal cords are often poorly preserved. His ultimate goal is to re-create the sound of the <em>Parasaurolophu<\/em>s\u2014and perhaps even design his own accessible plug-in to add dinosaur sounds to his musical compositions.<\/p>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/arstechnica.com\/science\/2024\/11\/one-scientists-quest-to-recreate-call-of-parasaurolophus\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A \u201cnear-crested lizard\u201d Reconstruction of the environment where Parasaurolophus walkeri lived during the Cretaceous.
