We approach this in two main steps. First, we estimate continuous contact force profiles from rigid-body impulses using a simple model based on Hertz contact theory. Next, we compute solutions to the acoustic wave equation due to short acceleration pulses in each rigid-body degree of freedom. We introduce an efficient representation for these solutions --\n            <jats:italic>Precomputed Acceleration Noise<\/jats:italic>\n            -- which allows us to accurately estimate sound due to arbitrary rigid-body accelerations. We find that the addition of acceleration noise significantly complements the standard modal sound algorithm, especially for small objects.\n          <\/jats:p>","DOI":"10.1145\/2185520.2185599","type":"journal-article","created":{"date-parts":[[2012,8,6]],"date-time":"2012-08-06T18:11:37Z","timestamp":1344276697000},"page":"1-9","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":28,"title":["Precomputed acceleration noise for improved rigid-body sound"],"prefix":"10.1145","volume":"31","author":[{"given":"Jeffrey N.","family":"Chadwick","sequence":"first","affiliation":[{"name":"Cornell University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changxi","family":"Zheng","sequence":"additional","affiliation":[{"name":"Cornell University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doug L.","family":"James","sequence":"additional","affiliation":[{"name":"Cornell University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2012,7]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1360612.1360623"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1618452.1618465"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1121\/1.1354200"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-460X(81)90346-1"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1243\/146441906X77722"},{"key":"e_1_2_2_6_1","unstructured":"Flores P.
