DEVICE FOR INCREASING AUDIO PLEASANTNESS OF CONSTRUCTION EQUIPMENT SOUND AND METHOD FOR INCREASING AUDIO PLEASANTNESS OF CONSTRUCTION EQUIPMENT SOUND

摘要

This device (A) for increasing audio pleasantness processes the temporal fluctuation characteristics of the natural world on the basis of human subjective and physiological response evaluations in a manner so as not to match or approximate the peak frequency component and the frequency component of a frequency band matching or approximating the casing (111) of an indoor machine (110) in which is mounted a drive component (fan, motor, or the like), and causes the driving of the drive component at a signal that is on the basis of the processed waveform (post-processing waveform example (102)).
