Pumping Up the Volume on Hearing Loss in Your 30s and 40s

Plus, 3 ways to prevent noise-induced hearing loss

Here’s a cheery thought as you sip your coffee: If you’re in your 30s, you could already have hearing damage — and you may not even know it. As audiologist Sharon Sandridge, PhD, explains, “Hearing is not like seeing. You know when your eyes are going. But it’s much harder to detect early hearing loss.”

But wait! If you know the signs to look for and take some preventive steps, you can stop hearing damage from happening (or getting worse). Dr. Sandridge walks us through it:

First job, first home … first hearing loss?

Hearing loss affects more than 36 million adults, and we’re not just talking about Nana. Nearly 20% of people in their 20s have some degree of hearing damage.

Generally, high-frequency hearing loss comes first, which means background noise and people talking sound muffled. Then the volume starts its gradual move towards mute. So what’s a young or middle-aged adult to do? Dr. Sandridge says the key is prevention and recognizing the early signs of noise-induced hearing loss.

The buzz on noise-induced hearing loss

Dr. Sandridge says the most common cause of hearing loss at 30 and 40 is excessive sound. “Any loud sound can cause noise-induced hearing loss, including music and the crowd at a sporting event.”

Here’s why: New research has shown that loud sounds break the microorganisms in your ear that help you hear. “Those microorganisms are responsible for dropping off neurotransmitters that allow our ears to function swiftly and properly,” explains Dr. Sandridge. “If they aren’t working, the ear doesn’t function the way it’s supposed to.”

The amount of damage depends on how loud a sound is and your length of exposure. “The louder the sound, the shorter that exposure time can be,” notes Dr. Sandridge.

Noise measured at or above:

  • 85 decibels (dB): This level is dangerous after more than eight hours of exposure (think the sounds of city traffic while you’re driving in your car).
  • 100 dB: At this level (think a stadium when it’s rockin’), you reach the danger zone after 15 minutes.

After 10 minutes at 100 dB, your hearing is now on the clock. “You only have five minutes left at that level for the rest of the day before you’re maxed out.”

Two signs of hearing loss in your 30s and 40s

Since damage to your ears often happens gradually, you might not notice it at first. According to the U.S. Centers for Disease Control and Prevention (CDC), nearly one in four people between the ages of 20 and 69 have measurable hearing damage — but think their hearing is excellent.

Two signs that should turn up the volume on your suspicions:

  • Tinnitus, or ringing in your ears: Tinnitus often occurs in the aftermath of ear damage. If you hear that telltale ringing with no source in sight, check with a doctor.
  • Difficulty hearing high-intensity sounds: As the damage to your ears accumulates, these muffled sounds become more permanent.

If you notice either of these signs, see an audiologist as soon as possible. “It’s hard to detect a hearing problem on your own early enough to prevent hearing loss,” Dr. Sandridge says.

“Mild hearing loss will show up on a hearing test, but YOU won’t notice it until after five years of excessive noise exposure. And if you keep fatiguing your ears, the hearing damage only gets worse.”

Three ways to prevent hearing damage

The good news is noise-induced hearing loss is 100% preventable, especially if you follow these three tips:

  • Wear hearing protection: “If you have to raise your voice to be heard, you are in a potentially dangerous situation for your ears,”says Dr. Sandridge. “So wear earplugs or earmuffs.”
  • Turn down the sound: “For Apple products, if you keep the sound around 50 to 60%, you can listen to it all day long,” notes Dr. Sandridge. “Bring the volume up to 80%, and you can clock in about 90 minutes. But at the max, your ears only have about two songs (or seven minutes).”
  • Give your ears a rest: Don’t be afraid to walk away or take a break if you’re exposed to loud sounds at concerts, sporting events, mowing the grass or other recreational activities.

When you should see an audiologist for a hearing test

Brace yourself. Dr. Sandridge recommends getting a hearing test as early as your 20s, even if your ears seem to be firing on all cylinders.


“After college is a good time to get a hearing baseline. Then, have your hearing tested every five years to see if there are any changes,” advises Dr. Sandridge.

She explains: “A hearing test gives us a line graph of your hearing sensitivity. Certain patterns tell us if the loss is due to excessive noise. If we see little dips, we’ll be more aggressive with our counseling to stop further damage or maintain the hearing you have.”

Hearing aids can help you hear all life has to offer

While Dr. Sandridge says the stigma still exists for wearing hearing aids (for young and old alike) they’ve come a long way in the last 15 years.

“They are so cosmetically appealing now,” relates Dr. Sandridge. “They are little and sit behind your ear. You can no longer see the wire going into your ear. They are also great quality and natural sounding devices.”

Finding the perfect hearing aid for you mostly comes down to your motivation. “There is an effort to wearing them. You have to clean them, put them in every day, and change their batteries or charge them. You have to want to do all that,” says Dr. Sandridge. “But if you do, it will be worth it.”
