OS-2760
Fluctuation Sound Analyzer pack
OS-2740
OS-2760
Feature
Sound quality evaluation pack OS-2740 quantifies sound by using six parameters of psychoacoustic evaluation; loudness, sharpness, roughness, fluctuation strength, AI (Articulation Index), tonality as well as conventional physical quantities such as frequency analysis or octave analysis. Comparative evaluation of recorded data assessed by time axis or second processing of calculated results by sound quality parameters can produce new original parameters to extract features in sound to be measured. It achieves improving of sound quality, reducing cost of test, speed-up of development period and so on.
Feature
Fluctuation Sound Analyzer OS-2760 makes clear sound features based on the two axes of frequency and fluctuating frequency by using new concept of "time fluctuation" as well as six parameters of physical quantities such as loudness, sharpness, roughness, fluctuation strength, AI (Articulation Index), tonality. Since "Fluctuation Sound Analysis" can be performed comprehensively for sounds with various fluctuation speeds, it is capable of dealing with a wide range of variable frequencies. It enables to make clear sound quality elements for sounds that are not so loud but annoying.
