DOI: 10.1121/1.4988321
Abstract: Assistive listening applications can be grouped into two categories: public announcements and live reinforcement. Each has unique needs. For public announcements, system temporal latencies of hundreds of milliseconds are irrelevant. For live reinforcement, temporal latencies… read more here.
