Let’s take the room from How To Tune A Sound System In 15 Minutes, add a balcony, and raise the ceiling. That’s it! Listen to my conversation with Lundberg for a more details on how it works. Put your measurements into the Speaker Coverage Calculator above. This calculator is designed to give you the least amount of level variation across the listening area, but there are many more variables at play here. So if the highest measured level in the audience is 100dB SPL, then no part of the audience may be lower than 94dB SPL. It doesn’t know about walls and other speakers, so it works best for single-speaker applications like balconies, side fills, and smaller venues.Ĭonsistent coverage means that SPL will not vary more than 6dB. The calculator will give you a consistent coverage result for any scenario, but unfortunately it’s not very smart. Lucky for you, Daniel Lundberg and I have created a great new speaker coverage calculator that makes this initial step quick and easy. In sound system design, step one is to define speaker coverage. Please send me a message if the embedded calculator above is not working.
