Abstract

Measurements of early-decay time and multivariable linear-regression techniques were used to estimate the 125-8000-Hz octave-band absorption coefficients of eight types of surfaces in university classrooms. The eight types were 'hard surfaces', 'paneled surfaces' (including hard seats and windows), 'glued-on acoustical tiles', 'suspended acoustical ceilings', 'carpeted surfaces', 'upholstered seats', 'porous absorbers' and 'Helmholtz-resonator absorbers'. In general, resulting estimates were statistically significant, physically realistic and in good agreement with previous results. Values for suspended acoustical ceilings were significantly lower than published data. © 2005.
