NEAR END LISTENING ENHANCEMENT CONSIDERING THERMAL LIMIT OF MOBILE PHONE LOUDSPEAKERS
Bastian Sauert, Peter Vary · RWTH Publications (RWTH Aachen) · 2011
In mobile telephony, listening enhancement is desired by the near end listener who perceives not only the clean far end speech but also ambient background noise.A typical scenario is mobile telephony in acoustical background noise such as traffic or babble noise.During continuous playback the thermal load of the small loudspeakers is a major limitation.In this contribution, we adapt two previous approaches to this constraint.Furthermore, the impact of a new speech PSD estimator and state-of-the-art noise PSD tracking algorithms on the system performance is evaluated.
