Microphone Reflection Filter




A recording microphone works much better if you use a Pop Filter in front of the microphone and a reflection filter behind the microphone. The reflection filter blocks sound from bouncing back in the rear of the microphone creating distortion and annoying transients in your recordings.

I made this Microphone Reflection filter from a Microphone Pop Filter, Paint Roller strainers, a mattress pad, and some miscellaneous hardware and paint.

Here are the list of items and tools:

  1. 2 each Bucket Paint Strainers
  2. 5/32 inch Pop Rivets
  3. Satin Black Krylon Paint
  4. Outdoor Double sided Permanent Tape
  5. A Pop Filter that clamps to a microphone stand
  6. 3X3 Metal Bracket that attaches two beans together - look in construction section of Home Depot
  7. A strong Microphone Stand with Boom Arm
  8. Acoustic Foam or find corrugated bed or box foam. In a pinch, you can also use egg crate.


  • Pop Rivet Gun
  • Denatured Alcohol or Paint thinner to clean parts for paint
  • Drill
  • Center Punch and Hammer
  • Clamps
  • Pliers and Locking wrench
  • Metal Cutting Snips

Step 1: I Bought a Pop Filter That Clamps to a Microphone Stand

This Pop filter can be obtained from Monoprice:


I bought the paint strainers at Wal-Mart for about $5.00.

Bend, straighten, and separate the hook end of the Paint Strainers.

Physically slide the ends into each other. Fit the Metal Beam bracket between them.

Clamp everything together

Using the Center Punch and hammer, Dent metal so the drill does not wander

Drill holes that will attach the bracket and the upper and lower paint strainers. Use the Pop rivets to attach the metal pieces.

Pop rivets are much better than screws for this type of job because they do not rattle loose under the vibrations of Audio systems

Step 2: Painting Parts and Foam

I painted the frame

I cut out the foam with a pair of shears and spray painted. It takes a can of paint for foam because it soaks it up

I used Double sided, 10 pound, outdoor tape to attach the foam to the frame. The Tape is super strong.

Step 3: End

The pictures do not do this justice

It came out great and it work well.

It is not as heavy as it looks.

Total cost was less than $100.

Good luck on Yours.

Thanks for the offer, but construction has started on my own version already :-) I record a lot of brass so am making a bigger one to try and handle the various angles brass will approach the mic.
