The paper presents the results of experimental studies of the effect of acoustic noise of the sound and infrasonic frequency bands on the auditory, visual, motor, tactile responses of a person, as well as on the time of making decisions. A method for estimating the time of human reactions was proposed, which was implemented by the authors as a software application for mobile devices. The obtained results unequivocally show an increase in the reaction time of all types under the influence of sound and infrasound noise even of a small level.
The paper deals with the assessment of the Chelyabinsk meteoroid energy based on long-period infrasonic waves in the atmosphere. A new technique is proposed, which utilizes the integral energy distribution in the power spectrum. The obtained results are in satisfactory agreement with the independent energy estimates.
This paper describes the results of experimental study influences of urban planning and green spaces on the acoustic transport noises. The contribution of green spaces to the acoustic noise attenuation is shown.
