Acoustic Characterization of Rooms Using Reverberation Time Estimation Based on Supervised Learning Algorithm

Applied Sciences, 2021
The measurement of reverberation time is an essential procedure for the characterization of the acoustic performance of rooms. The values returned by these measurements allow us to predict how the sound will be transformed by the walls and furnishings of

BIM-based reverberation time analysis [PDF]

Journal of Information Technology in Construction, 2021
Building Information Modeling (BIM) can store information of building elements and provide a computational platform for physical analyses for building systems. BIM can resolve several problems throughout various phases of design (as well as construction and operation).

Experimental Study on Source Level Estimation Techniques of Underwater Sound Source in Reverberant Water Tank [PDF]

한국해양공학회지, 2019
The acoustic power is used as a primary index characterizing underwater sound sources and could be defined by its source level. The source level has been assessed using various experimental techniques such as the reverberation time method and reverberant

Effects of Varying Reverberation on Music Perception for Young Normal-Hearing and Old Hearing-Impaired Listeners

Trends in Hearing, 2018
Reverberation enhances music perception and is one of the most important acoustic factors in auditorium design. However, previous research on reverberant music perception has focused on young normal-hearing (YNH) listeners.

Fast reverberation-reduction algorithm based on inexact matrix decomposition [PDF]

JASA Express Letters
Traditionally, matrix-based methods for reverberation reduction have prioritized a high signal-to-reverberation ratio over low time consumption. This letter describes a fast reverberation-reduction algorithm.

Study on Doppler characteristics of underwater bistatic reverberation [PDF]

MATEC Web of Conferences, 2019
Active sonar has two typical types of geometry configuration respectively named monostatic and bistatic like a radar system. In the monostatic scenario, co-located underwater transducers transmit and receive sound energy, while in a bistatic situation ...
