  • The subjective unwantedness felt from the noise sources in living and office environment has been evaluated by investgating the upper/lower limit of perceptual loudness of the noise. The limits were selected by the subject and the noise sources were analyzed to find out whether there is any correlation with Zwicker parpmeters and ACF fastors. It was found that the loudness of vacuum cleaner noise does not influence its perceived noiseness. Noises implicated in human such as floor walking noise and talking sound, are the most irritating noise in office environment.

  • This paper is to provide the basic way of a acoustical evaluation and efficient control noise by investigating the limits of perceptual loudness of living environment and by finding out any correlation between Physical characteristics of noise and psychoacoustic parameters. The limits of perceptual loudness were selected by the subjects in a chamber for residential and working environment. And the noise sources were analyzed to find out whether there is any correlation with Zwicker parameters and ACF factors. In this study especially, to set up the domestic evaluation grade about floor impact noise. we'd like to suggest the loudness Perception research result as fundamental resource for setting up the evaluation grade through the result that is based on annoyance. In the result of this research, upper limit of heavy-weight impact noise was L-60, and lower limit of it was L-50. On the other hand, upper limit of light-weight impact noise was L-70, and lower limit of it was L-55. It seemed that the loudness of noise from vacuum cleaner noise does not affect its perceived noisiness. Noises implicated In human such as floor walking noise and talking sound, are the most irritating noise in office environment.
