Calculating noise levels

At the early stage of planning of a target, calculations for noise levels are often made in order to resolve the sound source?s effect on the environment or how the target can be insulated from external noise. To make these calculations, commonly accepted calculation models, such as models for traffic, railway or industrial noise, are used .The mission of acoustical consulting is to provide buildings and other places with appropriate acoustical environment. The noise source as well as purpose of the place or room will be noticed when planning the target. By this way it is possible to prevent the noise in advance and make the room more comfortable for the user. Problems with acoustical design and planning are often related with insulating or damping the noise sources, properties of the structures and proper placement of the rooms.
