The necessity of dereverberation algorithms in hand-held speech communication systems is
discussed in this contribution. The study is based on a new measurement campaign with …

Head-related transfer functions, HRTFs, that is, the pair of acoustic transfer functions from a
sound source in anechoic space to the human ears, are important elements of binaural …

Closed-room scenarios are characterized by reverberation, which decreases the
performance of applications such as hands-free teleconferencing and multichannel sound …

Fast and robust acoustic system identification is still a research topic of interest, because of
the typically time-variant nature of acoustic systems and the natural performance limitation of …

ABSTRACT Recently proposed Head-Related Transfer Function acquisition methods
include head-tracking to allow unconstrained subject movements during the measurement …

Speech signals captured by the microphones of a speech communication device are often
distorted by interfering noise sources as well as room reverberation. Such degradations may …

Linear transmission systems are often characterized by their impulse responses. A simple
and fast approach to acquire these impulse responses is the normalized leastmean-square …

Identification and tracking of time-variant systems is relevant in many applications, such as
acoustic echo cancellation, active noise control, or in acoustics, eg, for fast acquisition of …

Head-related transfer functions (HRTFs) describe the free field sound propagation between
a sound source and the listener's ears and include all the cues which are evaluated …

Research in static and time-variant system identification has brought up a broad variety of
identification algorithms. In acoustics, eg, static measurements of transfer functions are …
