Abstract: The development of noise reduction algorithms for hearing aids HA is
not longer only related to the improvement of signal to noise ratio, but also
to the quality of hearing, e.g., binaural aspects of hearing. This is very important
for the recognition of the localization of sound sources but also for
an improved speech intelligibility in noisy situations due to spatial release
from masking effects. New design and signal processing algorithms for binaural
HA’s need to be tested and validated in different acoustical scenarios.
As it is too laborious and time consuming to perform sufficient numbers of
perceptual evaluations in different rooms with different acoustical parameters,
advanced acoustic modeling of different virtual acoustical environments
might be needed. Virtual acoustics in our research relates to the convolution
of the measured or simulated binaural signals head related transfer
functions - HRTF’s with the impulse response generated from a computer
model of a room using ODEON® software to simulate binaural sounds.
This study investigates the usage of virtual acoustics in the framework of
developing algorithms for binaural hearing aids. It evaluates and quantifies
the fidelity of binaural signals generated by commercially available virtual
acoustics software with respect to the localization of sound and speech intelligibility
in different acoustical scenarios.
