Performance degradation due to multipath noise for narrowband OFDM systems: channel-based analysis and experimental determination [PDF]
, 2015 The performance of OFDM systems over a multipath channel can strongly degrade due to the propagation delay spread. The distortion of the received signal over the fast Fourier transform window is referred to as multipath noise.

The percept of reverberation is not affected by visual room impression in virtual environments.
Journal of the Acoustical Society of America, 2019 Humans possess mechanisms to suppress distracting early sound reflections, summarized as the precedence effect. Recent work shows that precedence is affected by visual stimulation.

Spherical microphone array acoustic rake receivers [PDF]
, 2015 Several signal independent acoustic rake receivers are proposed for speech dereverberation using spherical microphone arrays. The proposed rake designs take advantage of multipaths, by separately capturing and combining early reflections with the direct ...

Spring Reverberation: A Physical Perspective [PDF]
, 2009 Spring-based artificial reverberation was one of the earliest attempts at compact replication of room-like reverberation for studio use. The popularity and unique sound of this effect have given it a status and desirability apart from its original use ...

Chinese Syllable and Phoneme Identification in Noise and Reverberation
Archives of Acoustics, 2014 Chinese is a tonal language, which differentiates it from non-tonal languages in the Western countries. A Chinese character consists of an initial, a final, and a tone. In the present study, the effects of noise and reverberation on the Chinese syllable,

Nonnative implicit phonetic training in multiple reverberant environments. [PDF]
, 2019 Speech intelligibility is adversely affected by reverberation, particularly when listening to a foreign language. However, little is known about how phonetic learning is affected by room acoustics.

Frequency-dependence characterization of electromagnetic reverberation in indoor scenarios based on 1-40 GHz channel measurements [PDF]
, 2019 A novel model for the reverberation time is proposed in this letter, based on room electromagnetics theory. While the commonly used models consider absorption based on a constant rate of wall interactions within a given time, the proposed model takes the
