Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room
Buildings, 2022 Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

Experimental Validation of the Model of Reverberation Time Prediction in a Room [PDF]
Buildings, 2022 It is well known that the uncertainty of input data has a great influence on the accuracy of room acoustics simulations. The aforementioned accuracy is significantly influenced by the selection of the acoustic properties of room-delimiting materials ...

Calibration of Consonant Perception to Room Reverberation [PDF]
Journal of Speech, Language, and Hearing Research, 2021 AbstractPurposeWe examined how consonant perception is affected by a preceding speech carrier simulated in the same or a different room, for a broad range of consonants. Carrier room, carrier length, and carrier length/target room uncertainty were manipulated.

Tuning of Estimated Sound Absorption Coefficient of Materials of Reverberation Room Method
Shock and Vibration, 2022 Acoustical materials are usually used for architectural design, ambient noise, and traffic noise to absorb sound. The sound absorption coefficient (SAC) is often used as the performance index of acoustical materials.

Effect of Diffusing Elements in a Reverberation Room on the Results of Airborne Sound Insulation Laboratory Measurements [PDF]
Archives of Acoustics, 2023 The main problem in the measurement of airborne sound insulation is the measurement of the sound power radiated by the barrier, in practice performed by measuring the sound pressure level and the acoustic absorption in the receiving room.

Denoising Directional Room Impulse Responses with Spatially Anisotropic Late Reverberation Tails
Applied Sciences, 2020 Directional room impulse responses (DRIR) measured with spherical microphone arrays (SMA) enable the reproduction of room reverberation effects on three-dimensional surround-sound systems (e.g., Higher-Order Ambisonics) through multichannel convolution ...

Sensitivity of Acoustic Voice Quality Measures in Simulated Reverberation Conditions [PDF]
BioengineeringRoom reverberation can affect oral/aural communication and is especially critical in computer analysis of voice. High levels of reverberation can distort voice recordings, impacting the accuracy of quantifying voice production quality and vocal health ...

Volumetric reconstruction of acoustic energy flows in a reverberation room [PDF]
Journal of the Acoustical Society of America, 2019 This study examines the spatial and directional properties of net energy flows in a reverberation chamber. Based on measurements with a spherical array, a method is proposed to estimate the flows of acoustic energy in the volume surrounding the array ...
