description: The object of research of the present work â modern sound-absorbing and sound-absorbing materials, constructions and means of personal protection. Subject of research â acoustic characteristics of modern sound-absorbing and soundproofing materials, constructions and personal protective equipment. Objective â to analyses modern sound-absorbing and sound-insulating materials, structures and personal protective equipment. The following tasks were solved in the work: â theoretical bases of soundproofing and sound absorption were considered; â modern soundproofing and sound-absorbing materials were analyzed; â the acoustic characteristics of modern soundproofing and sound-absorbing materials were analyzed; â modern means of individual and collective protection against noise were analyzed. It was determined that each group of soundproofing and sound-absorbing materials is suitable for different spheres of application. The most universal means of protection at production facilities are personal protective equipment (earmuffs, headphones, helmets). The following digital technologies are used in the work: official Internet portal of legal information (pravo.gov.ru), Polytechnic electronic library (elib.spbstu.ru), scientific electronic library (www.elibrary.ru), Microsoft Excel.
