Good understanding of sound field in open and closed spaces. Practical skills to model the relevant acoustical parameters e.g. speech intelligibility and sound pressure level. Students are trained to calculate, choose and configure optimal version of sound reinforcement system for special purposes.
- define the basic terms used for describing the sound propagation in space, both open and closed
- distinguish between the elements in the sound reinforecement chain according to their purpose and technical characteristics
- distinguish between different types of loudspeaker box designs and their advantages and disadvantages in sound reinforcement applications
- estimate the interaction between the space and the sound reinforcement system
- analyze the problem of instaling a sound reinforcement system in a given space depending on its acoustical properties and intended purpose
- design a sound reinforcement system with appropriate charactersitics and topology that will ensure the best possible conditions for transmission of acoustic information and is appropriate for a given space
- evaluate the quality of a sound reinforcement system and its adequacy for a given space based on acoustical measurements and computer simulations
