Abstract :
Microphone arrays are the most effective of the techniques that have been proposed for improving speech intelligibility in noise for the hearing impaired. Superdirective arrays are attractive since optimal performance can be obtained for a stationary random noise field. A constrained superdirective array suitable for hearing-aid applications is discussed in the paper
