Implementation of method for dynamic noise visualisation into educational process

Dynamic noise visualization represents ideal tool for clear and concise presentation of events not recordable with human eye and its implementation into educational process. Visualization is the right tool for students, that allows them to easily and effectively understand complex issues. This process of implementation is granted by modern instrumentation in conjunction with information technology. The _"acoustic camera“ is a measurement tool which joined the field of acoustics a few years ago. This technology analyses the actual sound scene, which consists of a superposition of different sound sources, into a visual sound map. The basic principle relies on accurate calculation of the specific runtime delays of acoustic sound emissions radiating from several sources to the individual microphones of an array. An acoustic map of the local sound pressure distribution at a given distance will be calculated using the acoustic data of all simultaneously recorded microphone channels.
