The multi-agent system for monitoring sound information (MAMS) in the environment is a set of agents for sound detection, analyzing, classification and transformation. The objective of this article is to propose a methodology from the detection of sound (specific agents) to the classification and decision making. In order to do the classification an agent must be implemented and regarding the situation it will generate a corresponding scenario. This agent will have as input, the sound, classification method, and the environment characteristics. Based on the information about environment the same sound can have different interpretation. MAMS implements the functions to ensure the required class of protection of people (working or living) and allows implementing an environmental safety system
