description: The topic of the final qualification work: Â«Research on the effectiveness of sound warning systems and evacuation controlÂ». The purpose of this study is to provide recommendations for improving the sound notification system. To achieve this goal, the following tasks were set: 1. Analysis of technical and scientific materials to ensure fire safety. 2. Conducting tests to assess the change in sound pressure level as a function of sound frequency. 3. Drawing up proposals for improving the sound notification system. 4. Drawing up a proposal for the implementation of a test method for sound alarms included in a cable line to maintain their performance in a fire. In the process of writing a master's thesis, tests were carried out to assess the change in the sound pressure level, depending on the frequency of sound when a signal passes through an obstacle. A method has been developed for testing sound alarms included in a cable line to maintain their performance in a fire. A variant of the standard sound mask of the Â«FireÂ» signal for the sound notification system is proposed. The assessment of the competitiveness of this signal is given.
