SOUNDS ODD by Elizabeth Holmes
Fun Facts on the Science of Sound

9. Snap, Crackle & Jaw Pop!

For some of us, the wave form (at right) is a familiar gremlin. It's the result of a jaw pop.

To hear what it sounds like on an audio track, listen for the faint, hollow pop that follows the word "You" in "Thank You" in this looped clip: click here.

For me, this annoying mouth noise makes an unwelcome appearance when I'm tired, dehydrated or tense. Several of my voice over colleagues have told me that they also cope with this problem.

Here's how we solve it. We either:

Stop it at the source, or
If it slips through, clean it up with audio software afterwards

If this kind of mouth noise is a problem for you, read on! Help's on the way.

QUICK ANATOMY LESSON

Doctors who specialize in treating "jaw pops" call this condition temporomandibular disorder (TMD). Here's a simple anatomy lesson that explains the mechanics involved:

The joint that attaches our 'jawbones' to our skulls is called the temporomandibular joint, (TMJ).
Muscles surrounding this joint allow for movement from side to side, and up and down.
When the TMJ is smooth and flexible, we talk, chew and yawn with ease.

Most people who have TMD have had a TMJ injury. It can be painful, even years later. It can also cause restricted movement, such as trouble opening the mouth, or having the mouth be stuck open. (!)

For voice actors, the most annoying part is the clicks, pops and grating noises that our ultra-sensitive microphones "hear."

STOPPING AT SOURCE

If you're cleaning up mouth noise from TMD on your audio tracks, the following remedies may help you stop these sounds at the source:

Apply moist heat or cold packs to swollen muscles.
Avoid extreme jaw movements.
Use relaxation techniques. The best pre-performance warm-up I've found so far is from Bettye Zoller. It involves a soft, open-mouthed yawn that gently stretches the jaw muscles.
If you grind your teeth, look into wearing a splint or night guard.
Balance the biting surfaces on your teeth if they're out of alignment.
Reduce inflammation of affected muscles with: a) over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) b) pharmaceutical prescription medication (see your doctor) c) low-level laser therapy d) TENS (Transcutaneous Electrical Nerve Stimulation) therapy, which is a mild electrical pulse that a TENS unit sends through affected muscles to relieve pain.
Correct your posture. Don't hold the phone between your neck and shoulder. Don't rest your chin on your hand.

SPECIALTY SOFTWARE

Yes, an ounce of prevention is worth a pound of cure. But if you need a pound of cure - because those wave-form gremlins are still popping up - there are a variety of options open to you.

Most voice over software programs offer a range of remedies for mouth noises. Training tips for the more popular programs are beyond the scope of this article, but stay tuned to VoiceOverXtra for Dan Lenard's upcoming webinar on Cleaning Up Your Audio.

In the meantime, I'm told that iZotope RX™ 2 editing software is the software of choice for "jaw poppers."

This is an audio repair toolkit that will help you suppress and remove unwanted noises. For details, please consult vo tech blogs and see iZotope RX™ 2's website at: www.izotope.com/products/audio/rx.

Thank you for this! I've never been able to get rid of that tiny click that seems to be in my jaw after an "L." But I found Audacity is a tremendous time-saver! Their Effect called "Click Removal" worked perfectly for me using their default settings.

Thank you, Elizabeth, for the nice mention in your TMJ article (don't ask me to spell that...I Can't!) And do by all means see your DENTIST. They recommend this gizmo you sleep in that helps the condition. But my exercise you mentioned, it's called "the YAWN SIGH" - the open mouth drops the jaws slowly and carefully with NO TENSION in the jaw hinges. Then, just let the jaws hang open like that for about three or four seconds and gently close. Thanks again for the mention. Great article.

Ken -- Thank you for the link to that fascinating article on yawning! Who knew that something so simple could have such amazing benefits.

Joel -- Thanks for the feedback on RX 2. It was recommended to me by another 'jaw popper' who said the same thing: "Works great, but requires work!"

Fred -- In the course of researching this article, I was surprised to learn that neck cricks (from holding a phone against your ear, for example) could cause jaw popping problems. It makes sense that chiropractic adjustments would bring relief. Thanks for sharing this.

iZotope Rx is my go-to plug in for any kind of audio forensics. It is truly amazing for buzzes, hums... you name it! For the really adventurous, it is great for sound design/FX! ie: Radio Imaging productions.
It's your doctor's scalpel for audio repair!

I have also suffered from this problem on occasions in the past. I have found a trip to my chiropractor for a thorough adjustment to my spine and jaw quickly corrects the problem.

Although I don't suffer from TMD I can speak to the efficacy of RX 2. It is a bit intimidating, though!

Fine, relevant piece (with damning graphic to make the point), thanks! The simple act of making a conscious effort to relax the throat - sometimes I was bringing a certain, entirely unnecessary tightness to the mic - can make the difference. This goes to that...
