In recent years, as more people stayed at home due to the pandemic, fireworks sales—and injuries—set records, reports the American Speech-Language-Hearing Association. This year, with the pandemic waning, people are more likely to venture out to city displays of fireworks, possibly reducing sales of home fireworks (and resulting injuries).
Fireworks, even simple sparklers, are well-known among emergency physicians as a major cause of painful injuries to the hands, arms and face. But whether you are watching a professional show or have purchased your own fireworks, hearing loss is also a real risk. And this kind of hearing is permanent.
Why are fireworks so loud?
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." Volume is measured in decibels. 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.
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.
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—and wear!—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:
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.
