Titel / Title: A survey on methods for blind acoustic dereverberation
Abstrakt Abstract:

Reverberation is a phenomenon in auditoriums such as concert halls and churches. Reverberation consists of a combination of multiple echoes, and its intensity and duration depend on factors such as the dimensions of the enclosure, materials used in construction and shape. Reverberation is desirable in music reproduction, however, it renders speech
unintelligible. Thus there is a requirement to control reverberation of speech. This thesis work investigates the performances of different signal processing algorithms applied to suppress reverberation. Theoretical methods which have been verified with simulations are tested with real measurements. This gives a practical evaluation of the performance to be expected in the use of the algorithms.
