How to find overall trouble spots in a room
Every surface in a room does not have to be treated in order to have good room acoustics. Here is a simple method of finding trouble spots in a room.
- Grab a friend to hold a mirror along the wall near a certain speaker at speaker height.
- The listener sits in a spot of normal viewing.
- The friend then moves slowly toward the listening position (stay along the wall).
- Mark each spot on the wall where the listener can see any of the room speakers in the mirror.
- Congratulations! These are the trouble spots in the room that need an absorptive material in place. Don't forget that diffusive material can also be placed in those positions.
