Previous investigations of BC-AC sound field sensitivity have used different estimation methods and report estimates that vary by up to 20dB at some frequencies. In this study, the BC-AC sound field sensitivity was investigated by hearing threshold shifts, ear canal sound pressure measurements, and skull bone vibrations measured with an accelerometer. The vibration measurement produced valid estimates at 400Hz and below, the threshold shifts produced valid estimates at 500Hz and above, while the ear canal sound pressure measurements were found erroneous for estimating the BC-AC sound field sensitivity. The BC-AC sound field sensitivity is proposed, by combining the present result with others, as frequency independent at 50 to 60dB at frequencies up to 900Hz. At higher frequencies, it is frequency dependent with minima of 40 to 50dB at 2 and 8kHz, and a maximum of 50 to 60dB at 4kHz. The BC-AC sound field sensitivity is the theoretical limit of maximum attenuation achievable with ordinary hearing protection devices.<\/jats:p>","DOI":"10.1121\/1.2434762","type":"journal-article","created":{"date-parts":[[2007,3,6]],"date-time":"2007-03-06T15:00:13Z","timestamp":1173193213000},"page":"1576-1587","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":43,"title":["Examination of bone-conducted transmission from sound field excitation measured by thresholds, ear-canal sound pressure, and skull vibrations"],"prefix":"10.1121","volume":"121","author":[{"given":"Sabine","family":"Reinfeldt","sequence":"first","affiliation":[{"name":"Chalmers University of Technology Department of Signals and Systems, Division of Biomedical Engineering, , SE-412 96 G\u00f6teborg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Stenfelt","sequence":"additional","affiliation":[{"name":"Chalmers University of Technology Department of Signals and Systems, Division of Biomedical Engineering, , SE-412 96 G\u00f6teborg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Good","sequence":"additional","affiliation":[{"name":"Chalmers University of Technology Department of Signals and Systems, Division of Biomedical Engineering, , SE-412 96 G\u00f6teborg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"H\u00e5kansson","sequence":"additional","affiliation":[{"name":"Chalmers University of Technology Department of Signals and Systems, Division of Biomedical Engineering, , SE-412 96 G\u00f6teborg, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023080309044522500_c4","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1177\/000348946006900101","article-title":"The mechanism of bone conduction","volume":"69","year":"1960","journal-title":"Ann.
