Continuing with our analysis and incorporating the valuable insights of Prof. Jaime Delannoy, our collaborator and renowned expert in Acoustics with a PhD in the field, we found that the original conditions of the rehearsal rooms at Wellington Barracks lacked sufficient diffusion and useful first reflections.
To address this issue, we strategically implemented four different systems of diffusion. The percussion section was allocated a 2D diffusion system to increase residual absorption and provide smooth reflections throughout the rest of the band, with particular emphasis on the back of the drummer. The “conductor” wall, or front wall, was equipped with a 1D diffusion system to enhance horizontal reflections near the conductor and capture the entire width of the room. Additionally, the side walls were designed to create diffusive areas at the listening height and generate late scattered sound waves effectively creating a sense of increased width within the room, despite its square shape.
One of the key objectives of the new acoustic strategy was to recreate the immersive atmosphere of a live recording room. However, considering the unique context of a rehearsal room, it is crucial to be able to discern and distinguish each instrument individually, while also being able to clearly perceive the instructions from the Band’s conductor. This is particularly important as the conductor needs to be able to perceive and respond to changes in dynamics during the rehearsal process.
