Few studies have been conducted to verify this process of acquisition for impact noise. However, results obtained on animals have demonstrated that an asymptote is reached after 1\u20132 h of exposure. These results have been confirmed in the present study on four human subjects using a 470- ms (B duration) impact noise at a rate of 1 pps. The above pattern of acquisition has been retested on two subjects exposed to the same impact for periods of 15\u2013150 min. An ATS of 15\u201320 dB was measured (Lp=102\u2013104 dBA) after 30\u201360 min of exposure. Recovery curves were determined for each exposure duration. They appeared to follow a logarithmic function of post-exposure time. It took from 30\u201350 min for one subject and from 4\u20135 h for other to completely recover. The time for total recovery did not seem to vary as a function of exposure time. Implications are drawn for damage risk criteria and for the study of the effects of impact noise on hearing.<\/jats:p>","DOI":"10.1121\/1.397957","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T18:57:10Z","timestamp":1129229830000},"page":"1681-1690","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["The growth of and recovery from TTS in human subjects exposed to impact noise"],"prefix":"10.1121","volume":"85","author":[{"given":"C.","family":"Laroche","sequence":"first","affiliation":[{"name":"Groupe d\u2019Acoustique de I\u2019Universit\u00e9 de Montr\u00e9al, C.
