Characteristics of the noise, reverberation time and speech-to-noise ratio found in day-care centers

Michel Picard

Abstract


The characteristics of the noise, reverberation time and speech-to-noise ratios were studied in active day-care centers. Noise measurements were collected for 24 sites accommodating groups of 1.5 to 5 years-old children. The results suggests that speech from conversations in parallel is the principal component of the so-called 'noise' problem lin day-care centers. The study also suggests pedagogical style as an important ingrediant of successful verbal communication beyond acoustical solutions.
