Comparison of Binaural RTF-Vector-Based Direction of Arrival Estimation Methods Exploiting an External Microphone

no code implementations11 Apr 2021 Daniel Fejgin, Simon Doclo

In this paper we consider a binaural hearing aid setup, where in addition to the head-mounted microphones an external microphone is available.

Coherence-Based Frequency Subset Selection For Binaural RTF-Vector-Based Direction of Arrival Estimation for Multiple Speakers

no code implementations18 May 2022 Daniel Fejgin, Simon Doclo

Recently, a method has been proposed to estimate the direction of arrival (DOA) of a single speaker by minimizing the frequency-averaged Hermitian angle between an estimated relative transfer function (RTF) vector and a database of prototype anechoic RTF vectors.

Assisted RTF-Vector-Based Binaural Direction of Arrival Estimation Exploiting a Calibrated External Microphone Array

no code implementations30 Nov 2022 Daniel Fejgin, Simon Doclo

This method exploits the external microphones to estimate the RTF vector corresponding to the binaural hearing aid and constructs a one-dimensional spatial spectrum by comparing the estimated RTF vector against a database of anechoic prototype RTF vectors for several directions.

BRUDEX Database: Binaural Room Impulse Responses with Uniformly Distributed External Microphones

no code implementations14 Jun 2023 Daniel Fejgin, Wiebke Middelberg, Simon Doclo

There is an emerging need for comparable data for multi-microphone processing, particularly in acoustic sensor networks.

Exploiting an External Microphone for Binaural RTF-Vector-Based Direction of Arrival Estimation for Multiple Speakers

no code implementations10 Jul 2023 Daniel Fejgin, Simon Doclo

In hearing aid applications, an important objective is to accurately estimate the direction of arrival (DOA) of multiple speakers in noisy and reverberant environments.

Comparison of Frequency-Fusion Mechanisms for Binaural Direction-of-Arrival Estimation for Multiple Speakers

no code implementations15 Jan 2024 Daniel Fejgin, Elior Hadad, Sharon Gannot, Zbyněk Koldovský, Simon Doclo

According to how the SPS are combined, frequency fusion mechanisms are categorized into narrowband, broadband, or speaker-grouped, where the latter mechanism requires a speaker-wise grouping of frequencies.
