The paper studies the current state of the art in the use of acoustic effects in the prevention and elimination of fires. For this purpose, the literature review method was applied. The well-known approaches to fire extinguishing and their impact on the environment are considered. Multifaceted studies by a wide range of scientists on the possibilities of the acoustic effect in fire extinguishing are noted. The analysis of literary sources showed the negative impact of both the fires themselves and the majority of fire extinguishing agents on the environment. Variants of the use of the acoustic effect for the prevention and elimination of fires of various combustible substances are considered. The influence of the frequency of acoustic waves, scanning speed, power, and other acoustic parameters on flame extinguishing is noted. The possibilities of using a deep neural network for flame detection have been studied. The limitations and advantages of acoustic technology and further prospects for its development as an element of environmental technologies are shown.

The purpose of this article is to analyze the impact of influencer marketing on trust, trust inclination and consumer purchasing intentions. In addition, this study aims to turn the negative perceptions of influencer marketing of companies into positive and raise awareness accordingly. SPSS 26 and Amos programs were used. In this study; Frequency, percentage, standard deviation, average, factor analysis, correlation and regression analysis were performed on the survey form data, which was easily distributed by sampling method and filled out completely by 411 Instagram users over the age of 18. Instagram influencer marketing has been found to have a positive and positive effect on confidence, confidence trend and consumer purchasing intentions.
