Relationship Between Chinese Speech Intelligibility of Elderly and Speech Transmission Index

open access: yesArchives of Acoustics, 2021
In this paper, the relationship between Chinese speech intelligibility (CSI) scores of the elderly aged 60–69 and over 70 years old, and speech transmission index (STI) were investigated through the auralization method under different reverberation time ...

The speech intelligibility and applicability of the speech transmission index in large spaces [PDF]

open access: yesApplied Acoustics, 2020
Abstract This paper aims to explore the influence factors of speech intelligibility and the applicability of the speech transmission index (STI) in large spaces, where the sound energy is unevenly distributed and non-exponentially decays. The subjective speech intelligibility tests were conducted in Mandarin (China mainland) in two large spaces with ...

Disruption of writing by background speech: The role of speech transmission index

open access: yesApplied Acoustics, 2014
AbstractSpeech transmission index (STI) is an objective measure of the acoustic properties of office environments and is used to specify norms for acceptable acoustic work conditions. Yet, the tasks used to evaluate the effects of varying STIs on work performance have often been focusing on memory (as memory of visually presented words) and reading ...

Experimental Characterization and Acoustic Correction of a Multipurpose Performance Hall: The Italian Theatre “Cavallino Bianco”

open access: yesBuildings, 2022
This study presents the retrofit acoustic dq1esign of the Italian theatre “Cavallino Bianco”. In its historical configuration, the hall had a curved roof with a pressed-plant fiber ceiling, which was demolished and replaced with a wooden roof without a ...

Effect of Power Amplifier Distortion on the Speech Transmission Index for Public Address Systems [PDF]

open access: yesArchives of Acoustics, 2022
The effect of the power amplifier on speech intelligibility in public address systems is often marginalised – i.e. it is assumed that it does not introduce significant signal distortion.

Visualization of Acoustic Comfort in an Open-Plan, High-Performance Glass Building

open access: yesBuildings, 2022
The aesthetic and functional appeal of high-performance, open-plan office buildings presents special challenges. Extensive use of glass at the building’s perimeter to improve visual comfort and office communication can negatively impact acoustic comfort ...

Speech transmission index from running speech: A neural network approach [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2003
Speech transmission index (STI) is an important objective parameter concerning speech intelligibility for sound transmission channels. It is normally measured with specific test signals to ensure high accuracy and good repeatability. Measurement with running speech was previously proposed, but accuracy is compromised and hence applications limited.

Comparison between Predictive and Measurement Methods of Speech Intelligibility for Educational Rooms of Different Sizes with and without HVAC Systems

open access: yesEnergies, 2023
Heating ventilation and air conditioning (HVAC) systems represent one of the main noise sources inside classrooms. This explain why HVAC systems require careful design, competent installation and balancing, and regular maintenance. Many factors influence
