Cat Bowen, Romper, looks at whether fireworks can hurt babies’ ears. Bowen, who is deaf, has a daughter who is hard of hearing, so she is particularly concerned about the impact of noisy fireworks, writing “that what little hearing we have, we want to protect at all costs.”
Bowen points to a Boys Town National Research Hospital report which states that “fireworks register at over 140 decibels of sound” and recommends safe distances for adults and children. Bowen writes that adults “need to be about 65 feet away from the fireworks to be considered safe,” but it’s more than double that for a child.
But what about babies? Bowen says that “it’s different with babies,” because there is no hearing protection gear made for infants under six months. So “[c]an fireworks hurt your baby’s ears?” “Absolutely,” says Bowen, who recommends that you limit your baby’s exposure, try using protective headphones, and “keep you and your baby as far from the fireworks as you can while still enjoying the view.”
Why the warning? Because some summer activities could cause exposure to hazardous noise levels. Stefanie Valentic, EHSToday, writes that “Ball State University audiologists are warning people to use hearing protection during activities that may expose them to hazardous noise this summer such as mowing the lawn, concerts and fireworks.” “[P]eople may suffer irreversible damage to their auditory systems after only brief exposure,” says Ball State audiology professor Lynn Bielski. Her colleague, Professor Blair Mattern, adds that “[e]xcessively loud noise, music or other sound exposure will damage our hearing. We need to take responsibility and protect it.”
Ed Pfeifer, TribLIVE, would agree. He asserts that ear protection now will pay huge dividends down the line. Pfeifer writes about the “crazy amount of abuse” the human body can take and yet continue to function. But, he adds, eventually there is a price to pay. For Pfeifer, the price was a “very slight drop” in his ability to hear. And the cause of his hearing loss? Pfeifer speculates that:
Numerous rock concerts, excessive gunfire and front row seats at the stock car races have all left their mark on the lobes on the sides of my head. But, I use power tools all the time and if I was a betting man I’d put my money on those tools as the main culprit.
He notes that “[c]hainsaws and circular saws run at about 110 decibels, most table saws hover around the 104 mark and the average confrontation with teenage children, 127.” Pfeifer knows he can’t go back in time and tell his younger self to wear ear protection, but he is doing that now “to preserve every last bit” of what hearing he has left.
So the best advice this summer–and every summer–is to protect your hearing today so that you have it tomorrow. If you use loud lawn and garden equipment, find quieter replacements—they exist–or, at the least, don’t start an engine before you put in a pair of earplugs or don ear muff protectors. And if your idea of summertime fun includes outdoor concerts, fireworks displays, or an afternoon at a race track or your workbench, always have a supply of earplugs handy. Ultimately, we must assume responsibility for our hearing.

Noise is a medical and public health problem, and yet people ignore it at their own peril. Most of us are exposed to too much noise every day. That may explain why the Centers for Disease Control and Prevention found that about 25% of adults age 20-69 had hearing loss, and that many people with hearing loss didn’t know they had it.
Which is why a recent article by Mark Fischetti in Scientific American, “A Loud Warning: Millions of People Do Not Protect Their Ears,” is particularly disturbing. Fischetti reports that while “many people know that they should use earplugs or earmuffs when mowing the lawn or partying at the club,” they don’t protect their ears against noise at home or at work. If you click the link to the article, you’ll see a frightening infographic that very clearly shows that millions of Americans are at risk of losing their hearing or suffering other hearing damage because they fail to protect their ears.
Maybe if people knew that noise caused hearing loss, tinnitus, and hyperacusis–none of which can be cured–they might be motivated to protect their hearing and fight for quiet.

In California, on his or her birthday a 16-year-old gets a driver’s license and, if he or she is lucky, a car.
One Dutch town is thinking about what may be an even better birthday present, the gift of good hearing: Dutch town considers giving birthday earplugs to all 16-year-olds.

If you follow the Centers for Disease Control and Prevention (CDC) recommendations to protect your hearing then be prepared for isolation and depression. The CDC’s February 2017 issue of Vital Signs states that continued exposure to unsafe sound levels can cause stress, anxiety, depression, isolation, and other health issues. So in order to protect your hearing, the CDC recommends everyone:
- Avoid noisy places.
- Use earplugs, earmuffs and noise canceling devices when in noisy places.
Amplified sound levels at restaurants, retail stores, movie theaters, health clubs, nightclubs, and other public places often are unsafe.
Following recommendation No. 1: You don’t go.
Following recommendation No. 2: Your ears can’t function properly.
Imagine if the “solution” to second hand smoke at a restaurant was to wear a protective mask over your nose and mouth. How could you possibly communicate and enjoy your meal? Hearing “protection” simulates the effects of hearing loss and inhibits your ability to communicate and enjoy the event. It also trains your ears to get used to the effects of hearing loss and may inhibit recognizing gradual hearing impairment.
The National Institute for Occupational Safety and Health (NIOSH), a part of the CDC charged with conducting research and making recommendations for the prevention of work-related injury and illness, is highly critical of earplugs and earmuffs and recommends they should only be used when engineering controls are not feasible to reduce noise levels. According to NIOSH, the noise reduction rating system (NRR) used for earmuffs and earplugs greatly overstates “protection” and therefore is not NIOSH approved. Workers often do not use hearing protectors properly, and they interfere with communication. If earplugs are removed for a short period in order to communicate, there can be immediate and irreparable injury. Even double protection (earplugs and earmuffs) is inadequate when exposure exceeds 105 dB.
Manufacturers mislead the public with overstated marketing claims. A Dow Industrial company markets their “Professional Earmuff” as “Our Highest-NRR Rated Earmuff (30 Decibels), Patented Twin Cup Design.” The really small print in the inside of the box states the Company:
[M]akes no warranty as to the suitability of NRR as a measure of actual protection from any noise level since such protection depends on the sound level (loudness), how long you listen to the loud sound, and how well you fit the earplugs (sic) in your ears…The NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire…[Company] recommends reducing the NRR by 50% for estimating the average amount of noise reduction provided.
Furthermore, no type of hearing protection or noise canceling device protects against low frequency sounds, which travel through your body causing stress and may damage unborn children. Accordingly, NIOSH’s primary recommendation of the most effective way to prevent noise-induced hearing loss (NIHL) is to “remove hazardous noise from the workplace or remove the worker from hazardous noise.”
If you follow the primary CDC and NIOSH guideline, avoiding noisy places, it results in the same isolation, depression, and other issues associated with hearing impairment. The only healthy solution is requiring safe amplified sound levels so no hearing protection is necessary–it doesn’t cost anything to Turn Up the Quiet.™ There are many architecturally safe and pleasing ways to reduce sound levels in public places: breaking up an open floor plan, using materials that absorb or diffuse sound on wall and ceiling surfaces, installing carpeting, curtains, and tapestries, and using attractive acoustic panels, to name a few. It is also good for business.
After meeting with a local health club, they agreed to institute a new “quiet” class with no amplified music on a trial basis. Management was surprised to hear positive comments from members who had simply stopped coming to classes due to the unsafe volumes. They learned that some members with hearing aids took them out, put in earplugs, and still found the classes unbearable. In a few months they added two more quiet classes.
It’s OK to ask the grocery store, the clothing store, and other retailers to turn off the amplified music while you are shopping. Many will happily accommodate you, and it encourages others to do the same. Some businesses are establishing regular “quiet” hours of operation and finding more satisfied, and even new, customers who spend more time at the establishment.
In addition, “silent discos” are gaining popularity, where instead of amplifying music through speakers it is “silently” delivered via Wi-Fi to smartphones for patrons to listen without disturbing others. The local mayor wants to try it as part of the Summer Concerts in the Park series. It will allow those who may not want amplification to enjoy the Park, and won’t interfere with nearby businesses or residents. The same technology can be applied to other music events such as outdoor exercise, and speech events, such as public ceremonies, political speakers, and other large public gatherings.
These and other creative ways to avoid unsafe levels will allow all of us to fully participate and enjoy public gatherings without the risk of injury.

How do noise cancelling headphones work? Royce Wilson, news.com.au, writes about noise cancelling headphones, the cure-all to our modern noisy world. But have you ever wondered how they actually work? Wilson reports that there are “two types of noise cancelling technologies for headphones — passive and active,” and he asked University of Queensland School of Information Technology and Electrical Engineering research fellow and lecturer Dr Konstanty Bialkowski about the different approaches. Dr. Bialkowski said that the passive technology is “like having a cup around your ear that reduces high-frequency noise” (“people talking or high-pitched squealing”), while active cancellation is for low-frequency noise (e.g., low-pitched hum like a car engine, aeroplane engine or a fan). With active cancellation, the headset, which has a microphone, “knows the distance between the microphone and your ear and it makes [a] complete opposite noise” to cancel out the distracting noise.

Maybe one day the Guinness Book of World Records will have a category for the most people sustaining auditory damage at one time at an indoor sports event? Because that’s what happened in Lawrence, Kansas, at the University of Kansas’ Allen Fieldhouse on February 13, 2017. A new world record was set for indoor noise at a sports event: 130.4 decibels. The previous “winner,” the University of Kentucky’s Rupp Arena, set a record of 126.4 decibels just two weeks earlier.
It was a great game, undoubtedly sold out. Kansas won in overtime, coming back from a 67-60 deficit with 1:13 to play in regulation to tie the game, and then won in overtime. The few disheartened fans who left early missed the conclusion of a one of the season’s best basketball games. Famed Kansas coach Bill Self called it “the most remarkable win I’ve ever been a part of.” But his ears, the players’ ears, the ears of team and fieldhouse staff, and those of the capacity crowd of 16,300, undoubtedly also suffered permanent auditory damage. That’s because 130.4 decibels is about as loud as a four-engine jet plane from 100 feet away, but the auditory injury threshold (the point at which a hearing injury may occur) is only 75 to 78 decibels.
Maybe one day the NCAA, which touts “Student-Athlete Well-Being” as one of its core principles, will show some concern for the auditory health of its student-athletes and ban this type of silly and dangerous competition at NCAA events.
But if not, then how about a contest to see how many NCAA student athletes and sports event attendees can be blinded at one time by the host NCAA institution shining powerful laser lights into the stands and team benches at the sports arena? Hey, a world record is a world record, right?
Or maybe reason will prevail and the people who have the power to stop this senseless and dangerous contest will come to their senses? They can’t say that they didn’t have notice, because my letter to the editor of The Kansas City Star was published on Monday, February 20th. Your move, NCAA.

Mack interviews audiologist Michele Abrams who spoke about limiting exposure to damaging sound:
When we think about decibel levels, when we think of loudness levels, it’s really incremental. It’s a logarithmic scale. It’s not a linear scale. So we know that 85 db is that critical level. Eighty-five db, eight hours a day, that’s your maximum. If it’s 90 db — five db greater — you have to cut your time in half.
While generally informative, Abrams’ comment unfortunately identifies 85 db, eight hours a day as the “critical level.” But this noise exposure level is too high. It was developed solely as an occupational noise exposure standard and should never be applied to the general public, certainly not to children. As Dr. Daniel Fink, a noted noise activist, wrote in, “What Is A Safe Noise Level For The Public?”:
In the absence of a federal standard, an occupational standard meant to prevent hearing loss appears to have become the de facto safe level for all public noise exposures. This is demonstrated by the use of 85 decibels as a safe sound level by hearing health professionals and their organizations, in media reports, and in publications, most often without time limits; by its use as a volume limit for children’s headphones marketed to prevent hearing loss, again without exposure times; and by general acceptance of higher indoor and outdoor noise levels in the United States.
* * *
Eighty-five decibels is not a safe noise exposure level for the public. In 1972, the National Institute for Occupational Safety and Health developed an 85 A-weighted decibel recommended exposure level to reduce the risk of hearing loss from occupational noise exposure. … Even with strict time limits, this standard does not protect all workers from hearing loss.
So what is a safe noise level for the public? Dr. Fink states:
In 1974 the Environmental Protection Agency’s (EPA’s) Office of Noise Abatement and Control (ONAC) adjusted the National Institute for Occupational Safety and Health recommendation for additional exposure time: 24 instead of 8 hours daily and 365 instead of 240 days annually. The EPA calculated the safe noise level for the public to prevent hearing loss to be a 70-decibel time-weighted average for a 24-hour period… The EPA did not adjust for lifetime noise exposure, now almost 80 years versus 40 work-years, so the real average safe noise level to prevent hearing loss is probably lower.
One thing is clear, allowing children to use earbuds or headphones without limiting volume and time exposure is a recipe for hearing loss. Since the federal government has abdicated its authority to regulate noise, and manufacturers are unlikely to design products that limit the user’s ability to deliver as many decibels as he or she wants, parents must step in to protect their children’s hearing. Here’s something that will help: Don’t allow your children to wear earbuds and headphones. Tell them that if they want to listen to music they must play it through a speaker. While this may be unpopular, know that you will be giving your children an important gift–the ability to listen to and enjoy music throughout their lifetimes.
