How to Protect Your Microphone From Sweat – Tips from an Audio Technician

The fitness instructor's verbal instructions are an important part of the exercise experience. One of the best ways to make sure everyone can hear your voice is to have a properly working microphone. But even a properly working microphone can be damaged by sweat if you’re not careful. As audio technicians, we’ve seen it all!

As an audio technician, we understand the importance of a properly working microphone. A well-functioning microphone can make the difference between a successful performance and fitness class failures. A microphone that is not working properly can make an performer's voice sound muffled or distorted, disrupting the entire event.

In our experience, there are a few signs to look out for when determining if a microphone is working properly.

  1. The first is that it should produce clear and natural sound. Any unwanted noise, such as hissing or static, is a sign of a faulty microphone.
  2. Secondly, a properly working microphone should be able to handle high sound pressure levels without clipping or distorting the audio.
  3. Finally, a good mic should be durable and reliable, able to withstand the rigors of a fitness classes regular use without breaking down.
With these factors in mind, it's easy to determine whether a microphone is working properly or not. So here are some tips on how to protect your microphone from sweat and prolong its life.

Tip #1: Use a Windscreen or Cover
A windscreen or cover is a simple accessory that fits over the microphone head. It can be made from foam or another moisture-resistant material. The windscreen is designed to protect the microphone from the wind, but it also helps to repel moisture. This will prevent any sweat droplets from getting on the microphone and causing damage.

Tip #2: Use a Sweatband
This option is a little more old-fashioned but equally effective. Simply secure a sweatband around your head, over the microphone head. This keeps the sweat from dripping down and damaging your microphone.

Tip #3: Heavy Sweat
If you’re really sweating profusely while teaching or training, you must use a microphone made for sweat exposure. We classify our microphones based on sweat ratings. Each microphone has a sweat rating located on our product pages. If you have questions about whether a specific microphone brand/model will work for your fitness classes reach out to our team.

Tip #4: Keep Your Microphone Dry
After your workout, make sure you thoroughly dry off the microphone components. Here are some helpful tips:

  • Use a clean cloth or towel and gently wipe the microphone down
  • Make sure to let the microphone air dry (in a cool dry location) after cleaning it to prevent any moisture from getting trapped in the head
  • Note, do not store in a box or sealed drawer immediately after using the microphone, this will lock in the moisture.

Tip #5: Store Your Mic Properly
When you’re done exercising, you should always store your microphone in a dry, cool place. Moisture can build up in the head of the mic and cause damage over time. Try not to leave your mic in direct sunlight or a humid environment.
