Acoustic and non-acoustic factors in modeling listener-specific performance of sagittal-plane sound localization

open access: yesFrontiers in Psychology, 2014
The ability of sound-source localization in sagittal planes (along the top-down and front-back dimension) varies considerably across listeners. The directional acoustic spectral features, described by head-related transfer functions (HRTFs), also vary ...

Closed-Form DoA Solution for Co-Centered Orthogonal Microphone Arrays Based on Multilateration Equations

open access: yesApplied Sciences, 2023
This study proposes a closed-form direction-of-arrival (DoA) solution derived from multilateration equations for microphone arrays of co-centered and orthogonal pairs.

Imaging local acoustic pressure in microchannels [PDF]

open access: yesApplied Optics, 2015
A method for determining the spatially resolved acoustic field inside a water-filled microchannel is presented. The acoustic field, both amplitude and phase, is determined by measuring the change of the index of refraction of the water due to local pressure using stroboscopic illumination.

Acoustic Reflector Localization and Classification

open access: yes2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
The process of understanding acoustic properties of environments is important for several applications, such as spatial audio, augmented reality and source separation. In this paper, multichannel room impulse responses are recorded and transformed into their direction of arrival (DOA)-time domain, by employing a superdirective beamformer.

Comparison of Direct Intersection and Sonogram Methods for Acoustic Indoor Localization of Persons

open access: yesSensors, 2021
We discuss two methods to detect the presence and location of a person in an acoustically small-scale room and compare the performances for a simulated person in distances between 1 and 2 m.
