1 - Do I need diffusers in my studio?
In small rooms, the priority is to have bass traps in the corners and acoustic tiles at the primary reflection points. Once these are installed, diffusion can be added to break up unwanted sound reflections without soaking up the remaining ambience.
2 - What are primary reflection points?
In a listening room (such as a studio control room or hifi room) there are a number of locations where sound from the studio monitors is reflected directly into the listener’s ears. The areas to the left and right and above the listening position are a priority and should be treated with acoustic tiles.
3 - Where should I place diffusers?
Diffusers should not be placed too close to a sound source or microphone. In a control room, they are best placed towards the back of the room on the walls and ceiling. For best results in a live room they should be distributed evenly around the walls and ceiling.
