Paper Title - Objective Stress Assessment Of Indoor Noises Based On Multiple Linear Regression Analysis
This paper proposes an objective assessment of stress under indoor noise conditions. In the proposed assessment
method, both a qualitative stress score and quantitative feature parameters are collected according to a sequence of various
indoor noises. The qualitative stress score is obtained by continuously evaluating the perceptual intensity of stress for a certain
period with a score ranging from 1 to 10 under indoor noise conditions. In addition, the quantitative stress score is
represented by a combination of various audio feature parameters consisting of psychoacoustic, spectral, and temporal features.
Finally, a multiple linear regression analysis is conducted on the pairs of the qualitative and quantitative stress scores
to design an objective stress score estimator. It is shown from the evaluation that the proposed stress assessment method
could estimate stress score with mean error of 1.06 and standard deviation of 0.92.
