1. Extraction of Loudspeaker- and room impulse responses under overlapping conditions
University essay from Uppsala universitet/Signaler och systemAbstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

2. SINGLE CHANNEL SPEECH DEREVERBERATION FOR ACOUSTIC SIGNALS
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : Reverberation in speech is one of the primary factors caused by delayed image of speech signal plus the intended speech signals. Reverberation degrades the quality of the speech signal when recorded by a distant microphone and in the hands free telephonic scenarios. READ MORE

3. Algorithms for estimating reverberation characteristics for single channel dereverberation
University essay from KTH/SignalbehandlingAbstract : Speech enhancement systems achieving a joint suppression of reverberation and background noise can be used in digital hearing aids, voice controlled systems or hands-free telephony. Demanding requirements for computational complexity, signal delay and speech quality must be fulfilled in order to achieve a satisfactory performance. READ MORE

4. A survey on methods for blind acoustic dereverberation
University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandlingAbstract : 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.
