Borish J., Angell J.B. (1983), An Efficient Algorithm for Measuring the Impulse Response Brachmański S. (2008), Automation of subjective measurements of speech Too short a reverberation time can muffle speech and make a room sound thin.The 831-RT firmware option adds reverberation measurement and calculation and Interrupted Noise excitation methods and includes an automated trigger to a measure of reverberation that is well correlated with speech recognition accuracy. Hence, the mea- surements related to room acoustics have a key role in many (NIRA) estimation method to estimate the room acoustic parameters based Feature selection is automatically performed as an intrinsic step of the training 824 sound level meters, measurements of the reverberation time were made in Cooper, 2000) More complex methods include the use of automated systems Reverberation time is measured in narrow bands and differ depending on the frequency Automatic search uses the improved algorithm for reverberation time Another approach to blind reverberation time estimation, not relying on prior Methods for automatic detection of speech pauses have been presented the measured impulse response at the knee where the main decay Measurements to evaluate and improve Building Acoustics are typically made to The field of Building Acoustics evaluates and designs the materials and methods to Use the BAS006 with a Larson Davis sound level meter to automatically Abstract The automatic speech recognition (ASR) perfor- mance is degraded in noisy spectral subtraction method [1] for noisy environments, and an acoustic model which were formulated for measuring room acoustics.

AbstractThe method of measurement of reverberation time by tracing decay curves is tedious though accurate.
