Abstract
New methods for obtaining impulse response of a room (ISO 18233) can be used in building acoustics for measurements of sound pressure level and reverberation time. In principle, application of MLS and swept-sine deterministic signals should help enhancing the effective signal-to-noise ratio and, therefore, the accuracy of measurements, compared to the classical interrupted noise method. The aim of this paper is to make the comparison between the two methods when implemented for low frequency measurements.
