Poetic Objects: Bachelardian Reverie, Reverberation and Repose in Claire Denis' 35 Shots of Rum
Film-Philosophy, 2023 This article draws on the interrelated concepts of reverie and repose in Gaston Bachelard's philosophy to approach Claire Denis' poetic foregrounding of objects in 35 Shots of Rum (35 Rhums, 2008). Connecting Bachelard's work on time to his later studies

Reverberation Mapping of Active Galactic Nuclei [PDF]
, 2004 Reverberation mapping is a proven technique that is used to measure the size of the broad emission-line region and central black hole mass in active galactic nuclei. More ambitious reverberation mapping programs that are well within the capabilities of Hubble Space Telescope could allow us to determine the nature and flow of line-emitting gas in active

Stacked reverberation mapping [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2013 Abstract Over the past 20 years reverberation mapping has proved one of the most successful techniques for studying the local (<1 pc) environment of supermassive black holes that drive active galactic nuclei. Key successes of reverberation mapping have been direct black hole mass estimates, the radius–luminosity relation for the ...

PSD estimation in Beamspace for Estimating Direct-to-Reverberant Ratio from A Reverberant Speech Signal [PDF]
arXiv, 2015 A method for estimation of direct-to-reverberant ratio (DRR) using a microphone array is proposed. The proposed method estimates the power spectral density (PSD) of the direct sound and the reverberation using the algorithm \textit{PSD estimation in beamspace} with a microphone array and calculates the DRR of the observed signal.

Phoneme-Based Ratio Mask Estimation for Reverberant Speech Enhancement in Cochlear Implant Processors [PDF]
arXiv, 2021 Cochlear implant (CI) users have considerable difficulty in understanding speech in reverberant listening environments. Time-frequency (T-F) masking is a common technique that aims to improve speech intelligibility by multiplying reverberant speech by a matrix of gain values to suppress T-F bins dominated by reverberation.

The control of reverberation [PDF]
The Journal of the Acoustical Society of America, 1993 The variety of programs that a good modern auditorium should accommodate, requires that reverberation should be controllable if each program is to merit optimal acoustical environment. Guidance from auditorium synthesis suggests that, in contrast with the usual doctrine stressing reverberation time, the sound level of the reverberant sound relative to ...

IEEE Access, 2020 Although sound source localization is a desirable technique in many communication systems and intelligence applications, the distortion caused by diffuse noise or reverberation makes the time delay estimation (TDE) between signals acquired by a pair of ...

Blind Signal Dereverberation for Machine Speech Recognition [PDF]
arXiv, 2022 We present a method to remove unknown convolutive noise introduced to speech by reverberations of recording environments, utilizing some amount of training speech data from the reverberant environment, and any available non-reverberant speech data. Using Fourier transform computed over long temporal windows, which ideally cover the entire room impulse ...
