Running time calculation for delay lines for large events
For events with large audiences, such as concerts or open-air shows, event technicians usually set up several loudspeakers. In addition to the main loudspeakers on the stage, additional loudspeakers are placed further back in the audience area to amplify the signal at the rear. This ensures that the sound from the stage is equally audible throughout the audience area.
At large events, the loudspeakers are so far apart that echoes become audible due to the travel time of the sound if all loudspeakers are driven with the same electrical signals. The sound from the rear speakers can then be heard earlier than the sound from the front speakers. To solve this problem, the signal for the rear speakers must be delayed. To calculate this delay, a program with a graphical user interface was developed as part of the practical course in Computer Science 2 (second semester of the Information Technology study program).
The program allows the event technician to load an image of the venue into the graphical interface and intuitively specify the scale and positions of the speakers. The program calculates the delay in milliseconds that needs to be set for each speaker. The result is output as a list of delays for each speaker, which the event technician can use to configure their speaker system.
