The reverberation time (RT) is an important parameter for characterizing the quality of an auditory space. Sounds in reverberant environments are subject to coloration. This affects speech intelligibility and sound localization. Many state-of-the-art audio signal processing algorithms, for example in hearing-aids and telephony, are expected to have the ability to characterize the listening envi...

A major problem in moving platform active sonar systems is the detection of targets in spatially distributed and Doppler-spread reverberation. This paper presents a novel space time adaptive prewhitener for reverberation based on a two-dimensional autoregressive model. The space time adaptive prewhitener jointly processes received data in angle and Doppler to improve the separation of a target ...

the quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. this acoustic quality can be characterized based on the reverberation time (rt), speech transmission index (sti) and the sound insulation. in this context, an acoustic study was conducted in an auditorium located in the higher...

Changes in acoustic parameters measured a room may depend on the location and orientation of sound source microphones or reverberation conditions room. As was found research presented this publication, is also influenced by thermo-hygrometric conditions. The article presents an experimental analysis involving impact temperature relative air humidity time. Since it very difficult to control real...

Current video games either pre-render reverberation effects into the sound effects or implement them at run-time using artificial reverberation filters. While interactive geometrical approaches can be used for more accurate acoustical modeling, the increased authoring complexity and the additional cost of geometrical calculations still appears to overshadow their potential benefits. This paper ...

The question of what is the optimal reverberation time for speech intelligibility in an occupied classroom has been studied recently in two different ways, with contradictory results. Experiments have been performed under various conditions of speech-signal to background-noise level difference and reverberation time, finding an optimal reverberation time of zero. Theoretical predictions of appr...

A combined approach for estimating a feature-domain reverberation model suitable for the robust distant-talking automatic speech recognition concept REMOS (REverberation MOdeling for Speech recognition) [1] is proposed. Based on a few calibration utterances recorded in the target environment, the combined approach employs ML estimation and blind estimation of the reverberation time to determine...

Artificial reverberation is an important music production tool with a strong but poorly understood perceptual impact. A literature review of the relevant works concerned with the perception of musical reverberation is provided, and the use of artificial reverberation in multisource mixes is studied. The perceived amount of total artificial reverberation in a mixture is predicted using relative ...
