Most of the existing frequency-invariant beamformers (FIBs) with circular arrays are
implemented with omnidirectional microphones, where uniform circular arrays (UCAs) and …

Enhancementof a desired speech signal in the presence of competing or interfering speech
remains an unsolved problem, as it can be hard to determine which of the speech signals is …

This article focuses on estimating relative transfer functions (RTFs) for beamforming
applications. Traditional methods often assume that spectra are uncorrelated, an …

Acoustic-scene-related parameters such as relative transfer functions (RTFs) and power
spectral densities (PSDs) of the target source, late reverberation and ambient noise are …

Speech enhancement in hearing aids (HAs) can take advantage of a wireless remote
microphone (RM) having a better signal-to-noise ratio than the HA microphones. However …

Estimation of acoustic parameters is of great interest but very challenging in the
multichannel microphone signal processing area. Existing methods either assume simple …

This paper introduces a speech enhancement algorithm for hearing assistive devices, eg,
hearing aids, connected to a remote microphone. Remote microphones are especially …

Estimating the parameters that describe the acoustic scene is very important for many
microphone array applications. For example, consider the power spectral densities (PSDs) …

Estimation of the acoustic-scene related parameters such as relative transfer functions
(RTFs) from source to microphones, source power spectral densities (PSDs) and PSDs of …

A hearing device, eg a hearing aid, comprises a) an input unit configured to provide at least
one time-variant electric input signal representing sound, the at least one electric input …
