Continuous Head-related Transfer Function Representation Based on Hyperspherical Harmonics [PDF]
Archives of Acoustics, 2023 Expressing head-related transfer functions (HRTFs) in the spherical harmonic (SH) domain has been thoroughly studied as a method of obtaining continuity over space. However, HRTFs are functions not only of direction but also of frequency.

Modeling the directivity of parametric loudspeaker [PDF]
, 2012 The emerging applications of the parametric loudspeaker, such as 3D audio, demands accurate directivity control at the audible frequency (i.e. the difference frequency). Though the delay-and-sum beamforming has been proven adequate to adjust the steering

A DIRECT ADVANCE ON ADVANCE DIRECTIVES [PDF]
Bioethics, 2010 ABSTRACTAdvance directives (ADs), which are also sometimes referred to as ‘living wills’, are statements made by a person that indicate what treatment she should not be given in the event that she is not competent to consent or refuse at the future moment in question.

Product directivity models for parametric loudspeakers [PDF]
, 2012 In a recent work, the beamsteering characteristics of parametric loudspeakers were validated in an experiment. It was shown that based on the product directivity model, the locations and amplitudes of the mainlobe and grating lobes could be predicted ...
