The effect of simulated room acoustic parameters on the intelligibility and perceived reverberation of monosyllabic words and sentences

Abstract

Individual acoustic parameters of reverberation have the potential to affect both the intelligibility of speech and the degree of perceived reverberation. The current experiments used monaural acoustic simulations to investigate the effect of reverberation time (RT) and direct-to-reverberant ratio (DRR) on word and sentence intelligibility at different levels of analysis (phonemes, words, and sentences). Perceived reverberation and recall of sentences were also assessed. Intelligibility and perceived reverberation decreased with increasing RT and decreasing DRR (particularly between 0 and À10 dB). Results indicate consistent effects of both RT and DRR on the intelligibility and perceived reverberation of words and sentences. V

Impact of face masks on voice radiation

“…It can be assumed that especially phonemes incorporating significant energy in the affected frequency range might show degraded intelligibility. The datasets from this study can be applied in follow-up studies similar to Fogerty et al (2020) or Kokabi et al (2019) using room acoustic simulations or virtual acoustics to analyze in more detail which way the masks affect speech intelligibility.…”

Speech Intelligibility Prediction Using Spectro-Temporal Modulation Analysis

“…In [59], HINT [60] and IEEE sentences were convolved with room impulse responses simulated using the image method. The sentences were processed subject to four reverberation times: T60 = 0.9, 1.2, 1.5, and 2.1 seconds, and three directto-reverberant ratios (DRR): 0, -10, -20 dB.…”

Condiciones acústicas en las aulas de clase: Una revisión de la literatura

“…Distintos estudios evidencian la necesidad de mejoras en la acústica de las aulas de clase dado los niveles actuales de los parámetros acústicos en comparación con los estándares a nivel mundial [39,40,41,42,43,44,45,46,47,48,49,50], razón por la cual el conocimiento de las medidas de mejoramiento anteriormente mencionadas sería útil para aumentar los niveles de calidad de la acústica en las instituciones educativas.…”
