Superdirective microphone arrays significantly enhance speech recognition for hearing-impaired individuals by reducing background noise. This advanced processing outperformed other methods, including directional microphones, in listening tests.

Area of Science:

  • Acoustics and Signal Processing
  • Hearing Science and Audiology

Background:

  • Microphone arrays can enhance speech recognition in noisy environments for hearing-impaired listeners.
  • Previous work evaluated array-processing techniques using AI-weighted array gain.

Purpose of the Study:

  • To evaluate speech intelligibility using delay-and-sum beamforming and superdirective processing for hearing-impaired subjects.
  • To compare array processing techniques against single omnidirectional and cardioid microphones.

Main Methods:

  • Speech intelligibility was measured using the speech reception threshold (SRT) and speech intelligibility rating (SIR).
  • Two array-processing techniques (delay-and-sum beamforming, superdirective processing) were tested.
  • Performance was compared to single omnidirectional and cardioid microphones.

Main Results:

  • Superdirective array processing demonstrated the highest effectiveness.
  • Cardioid microphone and delay-and-sum beamforming showed intermediate results.
  • Single omnidirectional microphone yielded the lowest performance.

Conclusions:

  • Superdirective processing offers the most significant improvement in speech intelligibility for hearing-impaired listeners.
  • Room size did not strongly affect the relative performance of the processing techniques.
  • SRT and SIR measures provided comparable intelligibility assessments.
