If we are trying to make our room 'sound better', we should start with our listening position... as well as the position of our loudspeakers.
Class activity: Acoustic treatment positioning
Class activity: Acoustic treatment positioning
Goal: Locate early reflection points for listening position
Student A sits in ‘mix position’ while student B holds mirror against each wall to find where student A can see the loudspeaker.
Place a post-it note to mark this location

Small group activity: Mapping early reflections
Small group activity: Mapping early reflections
Each group take TWO copies of each DIAGRAM.
Flip one of the diagrams to create a ‘mirror’ of the room.
Using a ruler or straight edge, draw a line between the ear of the listener and the loudspeaker in ‘mirror room’
The point of the wall where the line intersects will be where we need some acoustic treatment
