In a monophonic teleconference, for instance, it is much more difficult to distinguish between different speakers due to missing binaural cues. Spatial positioning of the speakers by means of binaural reproduction methods using head-related transfer functions (HRTFs) enhances speech comprehension. These HRTFs are influenced by the torso, head and ear geometry as they describe the propagation path of the sound from a source to the ear canal entrance. Through this geometry-dependency, the HRTF is directional and subject-dependent. To enable a sufficient reproduction, individual HRTFs should be used. However, it is tremendously difficult to measure these HRTFs. For this reason this thesis proposes approaches to adapt the HRTFs applying individual anthropometric dimensions of a user. Since localization at low frequencies is mainly influenced by the interaural time difference, two models to adapt this difference are developed and compared with existing models. Furthermore, two approaches to adapt the spectral cues at higher frequencies are studied, improved and compared. Although the localization performance with individualized HRTFs is slightly worse than with individual HRTFs, it is nevertheless still better than with non-individual HRTFs, taking into account the measurement effort.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Ramona Bomhardt\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3832545433\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783832545437\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Logos Verlag Berlin\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/03\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 153\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 4.36lbs","brand":"Ramona Bomhardt","offers":[{"title":"Paperback","offer_id":48450137719039,"sku":"9783832545437","price":53.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_66037a88-c357-4b1c-aceb-5e31855bb1f3.jpg?v=1777266374","url":"https:\/\/www.whiterainbookhouse.com\/products\/anthropometric-individualization-of-head-related-transfer-ramona-bomhardt-9783832545437","provider":"WR Book House","version":"1.0","type":"link"}
