The thesis addresses the field of sound reinforcement and the fundamental principles of audio engineering applied in live events. The theoretical part introduces the basic concepts of sound, audio signals, human hearing, and room acoustics, which significantly influence sound perception, followed by an overview of essential audio equipment.
The practical part of the thesis focuses on the analysis of low-frequency loudspeaker directivity under different placement configurations and the influence of phase and time delays on the propagation of sound waves. Configurations such as the classic L–R, central, distributed, cardioid, and end-fire setups are presented. The analysis was carried out using the L-Acoustics Soundvision software, which enables the simulation of frequency and amplitude response as well as directional characteristics, thereby allowing optimization of loudspeaker placement. The simulation results were confirmed by practical measurements, which showed good agreement with the actual values and validated the usefulness of simulations as an effective tool in sound system design.
The aim of the thesis is to demonstrate how software simulations can be used to optimize subwoofer placement and system parameters, with the results directly transferred to the digital signal processor. This approach reduces the need for extensive on-site testing, accelerates system setup, and ensures more predictable outcomes, thereby contributing to higher sound quality and an improved listening experience.
