ARTICULATION INDEX IN LARGE AIR-CONDITIONED LANDSCAPED OFFICES

The relationships between articulation index and some noise criteria f or indoor environmental design and assessment in large air conditioned landscaped offices are discussed in the present investigation. Result s show that good correlations exist between it, loudness level and the preferred speech interference level. However; the articulation index does not correlate very well with the equivalent sound pressure level and thus does not correlate with auditory sensation feeling of office workers.
