Why Do I Chew So Loud Even With My Mouth Closed? Tips to Do It Quietly

Have you ever been in a quiet room, munching on a snack, only to realize you can hear every single chomp and crunch echoing around you? I know I have. Even with my mouth closed, it seems as if the sound of my chewing is amplified.

So, why do some of us chew so loud, even with our mouths closed? That’s what we’re going to explore today.

The Science Behind Chewing Sounds

Before we dive into the reasons behind loud chewing, let’s take a moment to understand the science behind it. When we chew, our teeth, tongue, and jaw muscles work together to break down food. These actions produce a variety of sounds, such as crunching, smacking, and grinding. Even with our mouths closed, the sounds can still escape.

Sound Waves and Resonance

The reason we can hear these sounds so clearly is that they are transmitted as sound waves. When we chew, the sound waves travel through our teeth, bones, and other tissues, creating a resonance that amplifies the sounds. This is why we can hear our chewing even with our mouths closed.

The Eustachian Tubes

Another reason we might be able to hear our chewing so loudly is due to the Eustachian tubes. These tubes connect our middle ears to the back of our throats, allowing for air pressure equalization. However, they also provide a direct pathway for sound to travel from our mouths to our ears.

When we chew, the Eustachian tubes can carry the sounds directly to our ears, making it seem louder than it actually is.

Personal Factors That Can Amplify Chewing Sounds

Now that we know the science behind why we can hear our chewing, let’s explore some personal factors that can make our chewing sound even louder.

Sinus Issues

If you’re congested or have sinus issues, you might find that your chewing sounds louder than usual. This is because the sound waves can get trapped in the congested areas, making them seem more amplified.

Psychological Factors

Sometimes, loud chewing can be attributed to psychological factors. For example, if you’re feeling anxious or stressed, you might become more sensitive to sounds in general, including your own chewing. This heightened sensitivity is called hyperacusis, and it can make even the quietest chewing sounds seem deafening.

Jaw Structure and Bite

Our jaw structure and the way our teeth meet when we bite down can also influence the volume of our chewing sounds. If you have an overbite, underbite, or misaligned teeth, it might cause your chewing to be louder than normal.

Tips to Reduce the Volume of Chewing

Understanding the reasons behind our loud chewing, we can now explore various tips on how to chew quietly and make our eating experience more enjoyable for ourselves and those around us.

Take Smaller Bites

Taking smaller bites is a simple yet effective way to minimize chewing sounds. By reducing the amount of food in your mouth, you’ll need to apply less force when chewing, which can in turn decrease the volume of the sounds produced.

Moreover, smaller bites can aid digestion, as they are easier for your stomach to process, so you won’t be farting or burping later on. It also allows you to savor your food, letting you fully appreciate its flavors and textures, resulting in a more satisfying and enjoyable mealtime.

Chew Slowly and Gently

Rushed or forceful chewing can create louder and more abrasive noises. By consciously taking your time and being gentle with each bite, you’ll generate less noise and create a more peaceful eating environment.

Additionally, focusing on your jaw movements and avoiding clenching or grinding your teeth can further contribute to quieter chewing.

Remember to breathe through your nose while chewing, as it helps relax your facial muscles and reduces the intensity of your chewing.

Practice Mindful Eating

Mindful eating is a powerful tool for becoming more aware of the sounds we make while chewing and learning to adjust our habits accordingly. This practice involves paying close attention to the sensations and experiences of eating, such as the taste, texture, sight, smell, and sound of our food.

To effectively practice mindful eating, start by eliminating distractions like TV, smartphones, or computers, allowing you to concentrate solely on your meal. As you eat, make a conscious effort to chew your food thoroughly. Not only will this help reduce the volume of your chewing, but it will also improve digestion and help you feel more satisfied after eating.

Maintain Good Oral Hygiene

Keeping your teeth and gums clean and healthy can also contribute to reducing the volume of your chewing. Buildup of plaque or tartar on your teeth can alter the way your teeth come together when you chew, potentially increasing the noise produced.

Regular dental checkups, brushing at least twice a day, and flossing daily can help maintain good oral hygiene and possibly minimize chewing sounds.

Stay Hydrated

Dry mouth, which can result from dehydration, may cause an increase in smacking or clicking noises during chewing. Drinking water regularly throughout the day and having a glass of water nearby during meals can help keep your mouth moist, thereby reducing any additional sounds caused by dryness.

Adjust Your Eating Environment

Making small adjustments to your eating environment can also help. For example, using softer utensils, such as wooden or silicone spoons and forks, can help minimize clinking noises against your teeth or plates.

Additionally, adding soft background music or white noise during meals can help mask chewing sounds, making them less noticeable and potentially reducing any self-consciousness you may feel about the volume of your chewing.

When to Seek Professional Help

If you find that your loud chewing is causing significant distress or affecting your quality of life, you may want to consider seeking professional help. 

Auditory Processing Disorder

In some cases, loud chewing could be a symptom of an auditory processing disorder, which is a condition that affects how the brain processes sound. A hearing specialist, such as an audiologist, can help determine if you have an auditory processing disorder and recommend appropriate treatment options.

Misophonia

Another reason to seek professional help is if you suspect you may have misophonia. Misophonia is a condition characterized by an extreme sensitivity to specific sounds, often including chewing noises. It can cause intense emotional reactions, such as anger, anxiety, or disgust. If you suspect you may have misophonia, it’s important to consult a mental health professional who can help diagnose and manage the condition.

Dental Issues

As mentioned earlier, jaw structure and bite can impact the volume of chewing sounds. If you suspect that your loud chewing is related to dental issues, it’s a good idea to consult with a dentist. They can assess your teeth and jaw alignment, and recommend treatments or interventions to help address the problem.

To Sum Up

So, there you have it. Chewing loudly with our mouths closed can be attributed to a variety of factors, from the science of sound waves and resonance to personal factors like sinus issues, anxiety, and jaw structure.

By understanding these factors and implementing some of the tips mentioned, we can work towards reducing the volume of our chewing sounds.

And remember, if your loud chewing is causing significant distress or if you suspect an underlying condition, don’t hesitate to seek professional help.
