Speech intelligibility in rooms: Effect of prior listening exposure interacts with room acoustics

Effect of classroom acoustics on the speech intelligibility of students.

PURPOSE To analyze the acoustic parameters of classrooms and the relationship among equivalent sound pressure level (Leq), reverberation time (T₃₀), the Speech Transmission Index (STI), and the performance of students in speech intelligibility testing. METHODS A cross-sectional descriptive study, which analyzed the acoustic performance of 18 classrooms in 9 public schools in Belo Horizonte, M...

Factors Affecting Acoustics and Speech Intelligibility in the Operating Room: Size Matters

INTRODUCTION Noise in health care settings has increased since 1960 and represents a significant source of dissatisfaction among staff and patients and risk to patient safety. Operating rooms (ORs) in which effective communication is crucial are particularly noisy. Speech intelligibility is impacted by noise, room architecture, and acoustics. For example, sound reverberation time (RT60) increas...

The effect of binaural processing techniques on speech quality ratings of assistive listening devices in different room acoustics conditions

Prediction of binaural speech intelligibility against noise in rooms.

In the presence of competing speech or noise, reverberation degrades speech intelligibility not only by its direct effect on the target but also by affecting the interferer. Two experiments were designed to validate a method for predicting the loss of intelligibility associated with this latter effect. Speech reception thresholds were measured under headphones, using spatially separated target ...

Speech Intelligibility in Persian Children with Down Syndrome

Objectives: One of the most effective methods to describe speech disorders is the measurement of speech intelligibility. The speech intelligibility indicates the extent of acoustic signals that correctly speaker produces and hearer receives. The purpose of this study was to investigate the speech intelligibility in the Persian children with Down syndrome, age range was 3 to 5 years, who had spo...
