Opportunities for active noise control in communication headsets
Keywords:Acoustic variables control, Adaptive filtering, Feedback control, Speech communication, Speech intelligibility, Active noise control, Adaptive feedforward control, Headsets, Hearing loss
AbstractAlmost all commercial circumaural headsets incorporating active noise reduction (ANR) employ feedback control with fixed filters and analog signal processing. This combination provides, at best, a conditionally-stable device. However, inconsistent control of environmental noise results from air leaks in the seal between the earmuff and the head. The potential of improving speech communication and reducing noise-induced hearing loss in an ANR handset using adaptive feedforward control is presented.
