5 ways to protect your hearing this Fourth of July

By | July 3, 2020

When you think of celebrating Independence Day, the first thing that comes to mind is probably fireworks. After enjoying the 4th of July swimming, playing and barbecuing, many of us in the United States spend the evening oohing and aahing over a display of colorful and exciting pyrotechnics. But whether you are watching a professional show or have purchased your own fireworks, hearing loss is a real risk. 

Why are fireworks so loud?

Always keep a safe distance from fireworks.

It all comes down to the chemical reaction that happens after the fuse is lit. The burning gunpowder releases hot gas that expands rapidly; when the gas expands to the point that it runs out of room within the firework, the resulting explosion causes a blast wave.

The vibrations from that blast wave have the potential to cause permanent damage to the delicate hair cells of the inner ear.

Yes, they’re exciting, but the problem is the excitement is often measured by the “loudness factor.” For some people, the louder the better. And those loud explosions have the potential to reach levels between 150 and 175 decibels at close range.

At close range, fireworks are typically between 150 and 175 decibels—well above what’s safe for your hearing.

When it comes to fireworks, the World Health Organization recommends the maximum safe decibel level for adults is 140 decibels, and for children only 120 decibels. Fireworks often range right between a shotgun blast and a jet engine taking off:

Never expose babies to fireworks

Infants should not be exposed at all; an infant’s ear canal is much smaller than an older child’s or an adult’s, so the sound pressure entering the ear is greater. What might not sound that loud to an adult actually sounds up to 20 decibels louder to an infant.

Infants should not be exposed at all—their ear anatomy is too delicate.

5 ways to protect your hearing

1. Keep a safe distance

One way is to maintain a safe distance from the display. The farther you are from the sound, the less harmful the sound is to your ears, so your distance from the sound of the fireworks can make all of the difference in terms of decibel level and hearing safety. A distance of around 500 feet will still give you a great view, but without the sound pressure that can damage the tiny hair cells in the inner ear.

2. Skip the home displays

Where you view your fireworks can also affect your hearing. Experts recommend attending a community display rather than setting off your own fireworks at home. Not only are fireworks dangerous and best left to trained professionals, but there is usually a roped off area located a safe viewing (and listening) distance away from the show.

3. Bring earplugs and earmuffs

If you intend to sit as close to the action as possible, or if you are determined to create your own display, protect your hearing and that of your children. Inexpensive foam earplugs can be found in drugstores and pharmacies, and work well for adults; earmuffs (basically foam-filled cups that cover the ears) are better for small children because earplugs sometimes don’t fit and can be a choking hazard.

4. If you buy your own fireworks, buy these

If you are planning your own fireworks display, the good news is you can customize your selection for reduced noise. All fireworks come with a noise level rating, so selecting quieter fireworks will not only preserve a good relationship with your neighbors, it will protect your hearing as well. Quieter options include fountains, wheels, falling leaves and comets. While not completely silent, they crackle and whistle instead of creating a loud, explosive boom. All are created for spectacular visual display but less noise. If you buy fireworks, your fireworks provider should be able to direct you to those that are lower on the noise rating scale.

5. And avoid these 

What to avoid? Rockets, mines and any fireworks that have many blasts strung together tightly. These fireworks are created to make as much noise as possible.

Noise-induced hearing loss

Noise-induced hearing loss is one of the top ways Americans lose their hearing. Exposure to noises such as loud fireworks can result in:

  • Tinnitus
  • Slight temporary hearing loss (less than 24 hours)
  • Eardrum perforation (rare)
  • After repeated exposure, it can cause permanent hearing loss, especially as you get older

If you think you have temporary hearing loss after attending a fireworks display, see a hearing care professional—you can find a clinic in our extensive consumer-reviewed directory. And don’t worry; you can still have fun this Fourth of July while protecting your hearing from the eardrum-shattering booms. Protecting your hearing now will enable you to enjoy the sounds of the fireworks for years to come.
