An Enhanced Binaural 3D Sound Localization Algorithm
TL;DR: This work proposes a new binaural sound source localization technique based on using only two microphones placed inside the ear canal of a robot dummy head that is able to localize sound sources in free space with high precision and low computational complexity.

TL;DR: The technical details of the 3D Tune-In Toolkit are presented, outlining its architecture and describing the processes implemented in each of its components, followed by a comparison between the features offered by the 3DTI Toolkit and those found in other currently available open- and closed-source binaural renderers.

Perceptual Evaluation of Headphone Compensation in Binaural Synthesis Based on Non-Individual Recordings
TL;DR: In this paper, a method for measuring HpTFs reliably at the blocked ear canal was developed, and compared non-individual dynamic binaural simulations based on recordings from a head and torso simulator (HATS) directly to reality.

Efficient synthesis of room acoustics via scattering delay networks
TL;DR: In this paper, an acoustic reverberator consisting of a network of delay lines connected via scattering junctions is proposed, which allows for simulation of unequal and frequency-dependent wall absorption, as well as directional sources and microphones.

Using beamforming and binaural synthesis for the psychoacoustical evaluation of target sources in noise
TL;DR: The results indicate that SHB almost entirely restored the loudness (or annoyance) of the target sounds to unmasked levels, even when presented with background noise, and thus may be a useful tool to psychoacoustically analyze composite sources.

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.
