So far I&#8217;ve only been able to do so by applying PML underneath my structure and a acoustic diffuse field excitation by DFSWAVE on top of the structure. With this I could calculate the TL with the commandnpras,dfst,avg,all   ! print average transmission lossnThis however only yields correct results if I apply the PML.nIs there another way to calculate the diffuse TL without PML for example with the rayleigh integral (command PRFAR) or something similar?nThanks a lot.n<\/p>\n","protected":false},"template":"","class_list":["post-50582","topic","type-topic","status-closed","hentry","topic-tag-acoustics","topic-tag-diffuse-sound-field","topic-tag-sound-transmission-loss"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["22834"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["??\u00030"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["477"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50582"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","159336"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["136003"],"_bbp_last_active_id":["136003"],"_bbp_last_active_time":["2020-12-14 13:26:23"]},"test":"bcho"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50582","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50582\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50582"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
