Whether you’re a regular gym devotee or planning workout classes for the new year—first off, congrats for making your physical health a priority. And while a fitness center can be a fun and motivating place to do just that, it is also important to look after your hearing health while you’re there. Here’s why: noise exposure.
You may not even notice the high noise levels at first, amongst the upbeat, high-tempo pop music that often fills the background of the main gym. Or the cheerful yet commanding voice of your headset-wielding workout instructor. Both of which, are often blaring.
Just how blaring might they be? Well, recent research, for example, found that noise levels in fitness classes—from aerobic to spin—exceeded the maximum levels believed to be safe for hearing. So, even though the intent of loud music or booming instruction may be to boost motivation during workouts, the reality is that it may put you and your instructor at risk for noise-induced hearing loss.
What is noise-induced hearing loss?
Noise-induced hearing loss (NIHL) impacts nearly 40 million U.S. adults aged 20–69, according to the Centers for Disease Control and Prevention (CDC), and occurs when excessively loud noise damages the hair cells in your inner ear and the hearing nerve.
Noise can damage hearing immediately (if it’s sudden or impulse, like an explosion or firecracker near the ear) or over time (if it’s continuous and higher volume, such as music from earbuds—or regular visits to the gym).
The bad news: If the noise exposure is excessive, the hearing loss may be permanent and irreversible.
The good news: Protecting your hearing can help prevent the hearing loss from happening in the first place.
Here are four sensible things you can do to protect your hearing at the gym—so you can maintain your physical wellness and hearing health.
1. Know your noise levels
Paying attention to noise levels at your health club can help inform when or if you should take protective measures with your hearing.
According to the CDC, safe levels of noise exposure (measured in decibels/dB) are as follows:
- 85 dB for eight hours
- 88 dB for four hours
- 91 dB for two hours
- 94 dB for one hour
- 97 dB for half an hour
- 100 dB for 15 minutes
To give you some perspective on what you might expect at the gym: Research reported by the Noise and Health Journal showed that group fitness classes frequently exceed 90 dB and often exceed 100 dB—that’s similar to noise from a rock concert or a siren.
2. Wear hearing protection
The best way to protect your hearing from excessive noise at the gym (when it is unavoidable) is by wearing hearing protection devices. Worn in (earplugs) or on (protective earmuffs) your ears, these devices are designed to physically block sound waves from entering the ear so fewer decibels of sound can get in and potentially cause damage.
3. Limit your noise exposure
It could be as simple as taking a sip of water or toweling off for 30–60 seconds, just to give your ears a rest from noise. It also never hurts to find a place in class as far away from any speakers as possible, to limit your noise exposure.
4. Be an advocate for healthy hearing
If you find out your gym is exceeding safe noise levels, why not let your instructor or the gym manager know? If it’s too loud for you, you are likely not the only one.
