Build Your Own Microphone Pop Screen

One of the bigger hassles in editing voice audio tracks is cleaning up loud pops in the recording where plosive ‘p’ and ‘b’ sounds cause a burst of volume. These sounds are easily avoided by placing a screen between the person speaking or singing and the microphone.
By creating a fixed distance between the vocalist and the microphone you get the added bonus of reducing sibilant sounds made through speaking words with ‘s’ and ‘ch’.

Buying a microphone pop filter from a music supply store will set you back $20-30, depending on the quality of the screen and the stand it’s mounted on. It’s easy to build your own pop screen with some nylons and an embroidery hoop available at most craft stores for a couple of dollars.

Pop Filters Mitigate Sibilance and Plosives

Sibilance and plosive sounds do more damage to a vocal track than almost anything other than turning up the gain to the point of distortion. If you listen carefully to almost any recording you do both types of disruptive vocal tonalities are quite easy to pick out.

Sibilance is that lisping ‘s’ sound you hear from words that start or end with the official letter of Superman and shrill sounds generated from the ‘ch’ combination so popular with cats who adore curled cheese snacks. If you want to run a quick test, record the phrase, “A steel seal searches childish snakes for chewy chocolates.”

You can sometimes de-ess a recording in software after it’s finished by using multiband EQ to eliminate the offending frequencies or by running your entire recording through a de-essing plug-in. The best way to prevent overloading a recording with sibilant sounds is to talk into the microphone at a slight angle so the ‘s’ sounds don’t hit the microphone directly. Staying slightly off the microphone in the six-inch range also helps because the air between the microphone and your mouth gives the ‘s’ sibilant sounds a chance to dissipate.

Plosive sounds are the percussive vocal blasts created when speaking words with hard ‘p’ and ‘b’ sounds. The sounds create a volume spike which skews your recording and may distort audio with a loud pop where the sound appeared. Try recording the phrase, “Boldly balancing pickles on punks in poodle skirts.” Those bursts of vocal impact can be held in check quite easily by putting a pop screen (sometimes called a pop blocker or pop filter) in front of the microphone. A pop screen is basically a thin nylon or metal mesh stretched on a frame.

The one shown connected to the microphone stand here is available for about $20 from Guitar Center, but prices range up to $100 depending on what the screen and its supporting stand are made out of. The $20 unit pictured here works reasonably well, although the gooseneck on it isn’t as durable as units in the $30 range and the clip tends to wear out over time making it likely to slip down longer microphone stands.

You can build your own pop filter and flexible stand with more durability and all the pop elimination you need for slightly less money. If you already have some of these items (some worn out tights also work instead of panty hose) To make a pop screen and stand like the one I walk you through here you need the following items:

7″ Embroidery Hoop$3.27
Generic panty hose (or thin tights)$1.50
1/2-inch Split Flex Tubing$2.96
2 feet 10-2 Wire$4.70
7.5″ Black zip ties$1.74
1 1/4″ Compression fitting (from plumbing)$0.50
Optional 1″ Spring Clamp$2.09
Total Cost (as of February 2023)$16.76 ($14.67)
Scissors, nylons and embroidery hoop to make pop filter screen

In choosing parts for this, make sure you get a plastic embroidery hoop because the plastic hoops are more durable and there’s more space to work with on the compression fitting. The one shown here is a 6-inch Susan Bates Hoop-La from Wal-Mart. The panty hose need to be either thigh high or the pants-type so that you have enough material to work with. I used the cheapest generic brand I could find.

When you make the screen the first thing you need to do is cut off the top part of the pantyhose at thigh level, which leaves you with two separate leg pieces. Take one leg and cut a line from the thigh down to the toe. At the toe, cut the toe end straight across leaving you with a long rectangular sheet.

Nylon material in embroidery hoop for pop filter screen

After separating the embroidery hoop into two pieces, fold the pantyhose in half and stretch it across the inside hoop. Keeping the nylon hose as tight as possible, place the outside portion of the embroidery hoop on top of it and tighten the compression fitting so the two hoops hold the nylon snugly in place. You’ll be left with a square edge all the way around the hoop.

Trimmed excess nylon

Trim the leftover nylon so that no excess scrap is sticking out from the embroidery hoop. At this point, you have a finished screen capable of blocking pops with ease. Of course, you’re limited to holding the screen in front of the microphone throughout the record process, which may become tiresome.

Handheld pop filter screen in front of microphone

In creating a stand for my DIY pop screen, I have a few basic requirements: The stand needs to fasten securely to the microphone stand with no chance of slipping. The stand needs to be flexible so I can adjust it for different microphone stands and positions. It needs to be sturdy enough to support the weight of the screen while meeting the other two requirements.

Supplies for making a flexible pop filter stand

Based on my criteria and an afternoon spent in Home Depot, I decided 10-gauge electrical wiring provided the stability and flexibility required to support the weight of the screen while allowing me to bend it to adjust as needed. Split flex tubing hides the wiring providing a more polished look to the stand arm. A compression fitting meant to connect water piping holds the stand in place at the base and a zip tie secures the screen to the end of the stand.
The first thing I did was bend the 10-gauge wire into a shape meant to fit in front of the microphone. I covered the wire with the flex tubing up to the point where the wire gets fastened to the microphone stand.

Flexible tubing to cover wire used in pop filter stand

Secure the wire to the microphone stand with the compression fitting. Zip ties work here to but if you need to make adjustments you need to cut them and start over. With the fitting, just unscrew, adjust and tighten. Find the point where the screen will connect to the top of the wire and trim the flex tubing leaving any remaining wire exposed.

After marking the position on the wire covered by the screen, trim the wire to fit. I used a spring clamp to temporarily hold the screen in place while making adjustments but this certainly isn’t a required step. After trimming the wire, fasten the pop screen to the wire by running a zip tie around the wire and the metal screw of the compression fitting on the embroidery hoop. You now have a finished pop screen for under $20.
