The detection of environmental sounds that affect our daily life makes it possible to assess the suitability of the surrounding sound environment to the situation. In this study, EEGs of 20 healthy adults were measured and analyzed for changes in the frequency band power and event-related potentials. Consequently, pink noise, which changes its volume periodically, was found to easily reach the primary auditory cortex and induce changes in deep brain functions. In addition, a method for detecting environmental sounds in daily life, including such acoustic elements, is proposed. This method is developed by preparing 10-second samples of each environmental sound corresponding to the categories indicated in the environmental sound dataset ESC-50, except for short-time shot sounds. Periodic volume changes were extracted using autocorrelation analysis, and the presence of pink noisiness was determined using the flatness and crest values of the acoustic property index. Consequently, air conditioning, road repair, and washing machine sound samples were selected as typical environmental sounds containing the applicable sound elements, and all of the selected samples were long-lasting continuous sounds emitted by machines.
