EURASIP Journal on Applied Signal Processing

  Special Issue on
  DSP in Hearing Aids and Cochlear Implants

Digital signal processing for hearing aids was initiated as
a topic of research in the mid-late 1980s. However, it was
not until 1995 that technology was matured to a level where
size and power consumption made a market introduction of
hearing aids with full digital signal processing possible.
Today more and more hearing aids are turning digital even
in the low-price segments. Current technology enables hearing
aids that fit completely in the ear canal, and the
introduction of truly programmable platforms has allowed the
development of advanced digital signal processing algorithms
that provide a natural sound picture with increased speech
intelligibility and comfort to the hearing-impaired user.

Such signal processing technology is now also being adopted
in cochlear implants. A cochlear implant needs, in addition,
a sound processing strategy that converts the acoustical
signal into electrical signals to be applied to the
electrodes placed in the cochlea. The design of such sound
processing strategies poses additional signal processing
challenges, but at the same time builds on knowledge acquired
through physiological and psychophysical studies.

The goal of this special issue is to present research in
signal processing methods and algorithms for hearing aids
and cochlear implants.

Topics of interest include (but are not limited to):

 o Feedback cancellation
 o Noise reduction
 o Source separation
 o Adaptive directionality systems
 o Speech detection and recognition
 o Auditory scene analysis
 o Binaural signal processing
 o Filterbanks and compression
 o CI stimulation strategies
 o Psychoacoustically motivated signal processing algorithms
 o DSP architectures, complexity, parallel implementation
