Gobos are really useful things especially if you're working in a sub-par recording environment (ie. your living room). So what exactly is a Gobo?
Baffle - A physical object that absorbs or otherwise reduces the volume of sound which passes through it, or is reflected by it.
Gobo - see Baffle.
In other words, It absorbs or blocks sound. Those are the 2 main ways this effect can be achieved:
1. Absorbing the sound (converting it to heat via friction) - this is what foam, cloth, and other porous materials do.
2. Reflecting the sound (bouncing it back where it came from) - this is what concrete, and other non-porous materials do.
Here's a youtube video of the finished product:
Step 1: Gather your materials
note: Each step covers what to do for one gobo. You need to do the instructions from step 3 - 12 twice to complete both gobos.
- 16 feet of 2x12 lumber
- 12 feet of 2x4 lumber
- 2 - 2' x 2' pieces of 1/4" plywood
- 2 - handles (I used cabinet handles)
- Box of 2" wood screws
- Fiberglass insulation
- A cover for the absorptive side of the gobo
Step 2: Gather your Tools
Tools you'll need:
- Circular Saw
- Drill (with a 3/32" bit; A screwdriver bit would also be useful)
- Measuring Tape
- T - Square
Step 3: Cut your pieces
- (2x) 2x2 1/4" plywood
- (2x) 2x2 pegboard
- (4x) 2' long 2x12
- (4x) 1' 9" long 2x12
- (4x) 2' long 2x4
- (4x) 8" long 2x4
