The effect is caused by a motion of the skull that deforms the cartilage and bone to radiate sound into the ear canal.<br \/>\nAn anatomical finite element model of the outer ear is used to investigate details of the occlusion effect. The spatial distribution of the vibrations at the ear canal walls is analyzed for different types of excitation and the results are discussed for the open and occluded ear canal entrance. These simulations provide insights that could be used to develop measures to reduce the occlusion effect. Improving the knowledge of the occlusion effect may further benefit future algorithms.<\/p>\n<p><strong>Deutsch:<\/strong> Wenn der Geh\u00f6rgang durch Ger\u00e4te wie Kopfh\u00f6rer oder H\u00f6rger\u00e4te verschlossen wird, erh\u00f6ht sich die auditive Wahrnehmung von Knochenschall, was z. B. zu einer ver\u00e4nderten Wahrnehmung der eigenen Stimme f\u00fchrt. Der Effekt wird durch eine Bewegung des Sch\u00e4dels verursacht, die den Knorpel und den Knochen verformt, sodass der Schall in den Geh\u00f6rgang abgestrahlt wird.<br \/>\nEin anatomisches Finite-Elemente-Modell des Au\u00dfenohrs wird verwendet, um Details des Okklusionseffekts zu untersuchen. Die r\u00e4umliche Verteilung der Schwingungen an den Geh\u00f6rgangsw\u00e4nden wird f\u00fcr verschiedene Anregungsarten analysiert und die Ergebnisse werden f\u00fcr den offenen und geschlossenen Geh\u00f6rgangseingang diskutiert. Diese Simulationen liefern Erkenntnisse, die zur Entwicklung von Ma\u00dfnahmen zur Verringerung des Okklusionseffekts genutzt werden k\u00f6nnen. Die Verbesserung des Wissens \u00fcber den Okklusionseffekt kann zuk\u00fcnftigen Algorithmen dienen.<\/p>\n<p><a href=\"https:\/\/lists.rwth-aachen.de\/postorius\/lists\/akustik-kolloquium.lists.rwth-aachen.de\">Melden Sie sich hier an um Einladungen zu den Kolloquium-Vortr\u00e4gen per E-Mail zu erhalten.<\/a><br \/>\n<a href=\"https:\/\/lists.rwth-aachen.de\/postorius\/lists\/akustik-kolloquium.lists.rwth-aachen.de\">Register here to receive the invitations to colloquium talks via e-mail.<\/a><\/p>\n<p>Zoom-Meeting-ID: <a href=\"https:\/\/rwth.zoom.us\/j\/95440733814\">954 4073 3814<\/a><br \/>\nPasswort: 450783<\/p>\n","protected":false},"excerpt":{"rendered":"<p>English: When the ear canal is occluded by devices such as headphones or hearing aids, the auditory perception of bone-conducted sounds is increased, which results, e.g., in an alteration of [&hellip;]<\/p>\n","protected":false},"author":3556,"featured_media":0,"template":"","meta":{"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[74],"class_list":["post-2513","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-verteidigung-masterarbeit","cat_verteidigung-masterarbeit"],"_links":{"self":[{"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tribe_events\/2513","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/users\/3556"}],"version-history":[{"count":1,"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tribe_events\/2513\/revisions"}],"predecessor-version":[{"id":2514,"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tribe_events\/2513\/revisions\/2514"}],"wp:attachment":[{"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/media?parent=2513"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tags?post=2513"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/akustik\/wp-json\/wp\/v2\/tribe_events_cat?post=2513"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
