Binaural Rendering with Measured Room Responses: First-Order Ambisonic Microphone vs. Dummy Head
TL;DR: This work investigates the perceptual characteristics of dynamic rendering from MOBRIRs and test for the required angular resolution, finding that a resolution between 15 ∘ and 30 ∘ is sufficient to accomplish binaural rendering of high quality, regarding timbre, spatial mapping, and continuity.

Fast continuous HRTF acquisition with unconstrained movements of human subjects
TL;DR: The proposed continuous HRTF acquisition technique relies on the activation based normalized least-mean-square (ANLMS) algorithm to extract HRTF on the fly, which validated the accuracy of the proposed technique, when compared with the standard static acquisition technique.

Efficient Representation and Sparse Sampling of Head-Related Transfer Functions Using Phase-Correction Based on Ear Alignment
TL;DR: A new method for pre-processing HRTFs in order to reduce their effective order, which uses phase-correction based on ear alignment, by exploiting the dual-centering nature of HRTF measurements, making it more robust to measurement noise.

Physical characteristics of headphones used in psychophysical experiments
TL;DR: In this paper, the IEC coupler, dummy-head and actual-ear responses, harmonic distortion, impulse response decay, phase rotation and group delay, external sound radiation, sound attenuation and acoustic crosstalk characteristics of six models of headphones, the TDH39, DT48, HD250 Linear II, HD414 Classic, HDA 200 and SR-Lambda Professional, are measured and compared.

Coupling of earphones to human ears and to standard coupler
Dejan Ciric,Dorte Hammershøi +1 more
TL;DR: The results indicate that significant difference appears among sound pressures generated in different individuals' ears, and the earphone couplings to human ears and to the coupler differ considerably.

Simulation of the transient and steady‐state sound propagation in rooms using a new combined ray‐tracing/image‐source algorithm
TL;DR: The new method combines the advantages of the ray‐tracing process, namely, the relatively slow increase of computation time with the length of the impulse response, with the accuracy inherent to the image‐source model, which is even sufficient to calculate the Fourier transform.

Transformation characteristics of the external human ear
S. Mehrgardt,V. Mellert +1 more
TL;DR: With an impulse response technique the transfer functions from the free sound field to the ear‐canal entrance were measured on 20 subjects for sound incidence and the eardrum impedance was computed from this transfer function and completes the poor knowledge of the eARDrum impedance in the frequency range from 2 to 15 kHz.

Directional sensitivity of sound‐pressure levels in the human ear canal
TL;DR: The results indicate the types of horizontal and vertical spatial information that are available from sound level cues over various ranges of frequency and, within a small subject population, indicate the nature of intersubject variability.

ODEON—Another hybrid room acoustical model
TL;DR: The ODEON room acoustics program is intended to be a base for research in objective and subjective room acoustic research, and a useful tool for consultants, in which an initial ray tracing is carried out to determine potential reflection sequences.

Spectral cues utilized in the localization of sound in the median sagittal plane
TL;DR: A series of experiments carried out to further elucidate the role of spectral cues in locating sounds in the median sagittal plane (MSP) revealed a notch in the frequency response curves which migrated toward the lower frequencies as the sound source was moved from above to below the aural axis.
