Noise reduction technologies implemented in head-worn preprocessors for improving cochlear implant performance in reverberant noise fields

Speech reception threshold benefits in cochlear implant users with an adaptive beamformer in real life situations

“…The design of the test environments was chosen to be particularly challenging to better represent a realworld noisy environment, rather than to maximize the possible measurable benefit in a laboratory setting. All tests were conducted in a room with a moderate average T 60 reverberation time of 0.6 seconds, higher than the T 60 of 0.5 seconds reported in Spriet et al (2007) and the 0.4 seconds reported by Chung et al (2012). A reverberation time of this length could be considered to be similar to the maximum value for a classroom environment in line with the American national standard on classroom acoustics (American National Standards Institute S12.…”

Application of Noise Reduction Algorithm ClearVoice in Cochlear Implant Processing

“…Single-microphone algorithms perform best in situations with stationary noise, whereas multi-microphone algorithms work best in conditions where speech and noise come from different directions in low-reverberant surroundings (e.g., Spriet et al 2007;Chung et al 2012;Hersbach et al 2012;Kokkinakis et al 2012). Among these technologies are noise reduction algorithms (NRAs).…”
