Detailed Directivity of Sound Fields Around Human Talkers

This report presents detailed measurements made in the anechoic chamber at IRC of the sound fields around human talkers. The measurements were made on behalf of Public Works and Government Services Canada (PWGSC). The sound field surrounding a human talker was measured simultaneously by two sets of eight microphones arranged at fixed positions on two fixed orthogonal meridian arcs in the anechoic chamber at IRC. The talker was positioned at the center of the two arcs of the microphone arrays. To complete the survey of the whole sound field surrounding the subjects, each talker rotated to six fixed positions in 15-degree increments.Le rapport pr\ue9sente les mesures d\ue9taill\ue9es des champs acoustiques autour des locuteurs humains effectu\ue9es dans la salle an\ue9cho\uefque de l'IRC. Les mesures ont \ue9t\ue9 faites \ue0 la demande de Travaux publics et Services gouvernementaux Canada (TPSGC). Le champ acoustique qui entoure un locuteur humain a \ue9t\ue9 enregistr\ue9 simultan\ue9ment par deux jeux de huit microphones dispos\ue9s \ue0 des emplacements d\ue9finis, sur deux arcs m\ue9ridiens fixes, dans la chambre an\ue9cho\uefque de l'IRC. Le locuteur \ue9tait plac\ue9 au centre des deux arcs form\ue9s par les ensembles de microphones. Pour \ue9tudier la totalit\ue9 du champ acoustique qui entourait les sujets, on a demand\ue9 \ue0 chaque locuteur de se d\ue9placer le long des six emplacements fixes par incr\ue9ments de 15 degr\ue9s.Peer reviewed: NoNRC publication: Ye
