Comparison of binaural auralisations to a real loudspeaker in an audiovisual virtual classroom scenario: effect of room acoustic simulation, HRTF dataset, and head-mounted display on room acoustic perception*

Acta Acustica
In this study, auralisations of a real room were compared to the actual acoustics of that room using listening tests. Participants sat in a room and wore a combination of a head-mounted display (HMD) and headphones, and rated different room-acoustic ...

Listener perception of changes in historically informed performance of solo baroque music due to room acoustics

Acta Acustica
A listening test was performed to determine whether there were any perceived differences in the playing styles of musicians as a function of the room in which the music was performed.

Comparison of speech intelligibility in a real and virtual living room using loudspeaker and headphone presentations

Acta Acustica
Virtual acoustics enables hearing research and audiology in ecologically relevant and realistic acoustic environments, while offering experimental control and reproducibility of classical psychoacoustics and speech intelligibility tests.

Digital Adaptive Echo-Canceller for Room Acoustics Improvement

Advances in Electrical and Computer Engineering, 2010
This paper presents a method to cancel the echoes generated by reflections in a room. The starting point is the full-band adaptive system identification method, where the unknown system is the room, providing several reflections of the sound.

Modeling Measurement Uncertainty in Room Acoustics

Acta Polytechnica, 2007
This paper investigates a way of determining and modeling uncertainty contributions in measurements of room acoustic parameters, which are commonly used to describe the acoustic situation of a room in an objective manner.

Modelling of Green function in a rectangular room based upon the geometrical-filtration model

Archives of Acoustics, 2014
Significant problem in room acoustic is evaluating an acoustic quality of projected and modernized rooms. Estimation of room impulse response giving posibility to evaluate the subjective and objective room acoustic properties and hence to run the room ...

Cognitive load associated with speaking clearly in reverberant rooms

Scientific Reports
Communication is a fundamental aspect of human interaction, yet many individuals must speak in less-than-ideal acoustic environments daily. Adapting their speech to ensure intelligibility in these varied settings can impose a significant cognitive burden.

A room acoustic calibration method for vanished architectural spaces using archival sound: A case study of the Bürgerbräukeller (1885–1979)

Acta Acustica
Virtual reality auralizations offer the opportunity to interactively explore historic buildings and sites through immersive auditory experiences. In the context of historic auralizations, the calibration of room acoustic simulation models is often ...
