About the group

The Centre for Applied Hearing Research (CAHR) was established in 2003 to conduct fundamental and applied research with focus on human speech communication, auditory processing and perception, hearing impairment and hearing instruments. CAHR is a research centre within the Hearing Systems (HEA) group at the Department of Electrical Engineering. The purpose of CAHR is to promote research and education witin the field of acoustic communication with emphasis on:

  • Signal processing principles in the human auditory system
  • Perceptual consequences of hearing impairment
  • Functional models of auditory processing and perception
  • Applications of auditory models in hearing instruments
  • Measurement and diagnosis of auditory function
  • Technical audiology
  • Speech perception and production

Projects

CAHR is the main host of two INSPIRE projects:

  • Project ID-1: "Characterization and prediction of the perceptual consequences of hearing loss" with the aim to better characterise various types of hearing loss, based on estimates of sensitivity, cochlear compression, frequency selectivity, temporal resolution, intensity discrimination, cognitive capabilities, and their relation to performance in different speech intelligibility tests, including consonant identification and sentence recognition.
  • Project MIP-3: "Modelling speech intelligibility based on the signal-to-noise ratio in the modulation domain" with the aim to better understand why current intelligibility models often fail to predict the intelligibility improvements obtained by noise reduction techniques, and to develop improved models capable of providing accurate estimates of the effect of signal processing on intelligibility. This work is especially relevant for the development and evaluation of algorithms for hearing-instruments, but also has applications in context- and listener-specific speech modification to improve communication with speech technology for groups such as the elderly or non-natives in adverse conditions.

CAHR is also the second host of INSPIRE projects ID-3, MIP-2, MIP-4, and ENR-1.
