Fireworks Peak at 170 dB. Your Child’s Safe Limit Is 120. Here’s What Every Parent Needs to Know.

Key Takeaways

Fireworks are among the loudest sound events most children will ever encounter. A single shell bursting overhead produces between 140 and 170 decibels of peak sound pressure, compared to the WHO’s recommended limit of 120 dB for children, and the damage it causes can be permanent after just one display without protection. According to the CDC, approximately 12.5% of children and adolescents already live with some degree of noise-induced hearing loss, and fireworks are among the most common single-event causes. The difference between a memorable evening and lasting hearing damage is a pair of well-fitted earmuffs or earplugs, and knowing which option is right for your child’s age before you arrive at the display.

How Loud Are Fireworks Compared to Safe Noise Levels for Children?

A professional fireworks shell exploding overhead reaches between 140 and 170 decibels of peak sound pressure, a level that exceeds the World Health Organization’s maximum recommended limit for children by 20 to 50 dB and that is capable of causing irreversible hearing damage from a single exposure.

The WHO sets the peak sound pressure limit at 120 dB for children and 140 dB for adults, recognising that children’s developing auditory systems are more sensitive than those of adults. For context, 85 dB is the threshold at which sustained exposure begins to harm hearing over time. Fireworks don’t give the cochlea time to adapt. The impulse noise arrives in a fraction of a second, and the hair cells inside the cochlea that convert sound into neural signals have no mechanism to protect themselves from sudden acoustic peaks.

The situation is made worse by the nature of a fireworks display itself. Unlike a concert, where sound levels build gradually and families can step further from a speaker bank, a fireworks show delivers dozens of sharp, high-amplitude impulse events across 20 to 30 minutes with no warning between each burst. Each individual burst in the 140 to 170 dB range is a separate acoustic event that, on its own, exceeds the threshold for immediate cochlear damage in children. The NIDCD at the National Institutes of Health confirms that noise-induced hearing loss is entirely preventable and entirely irreversible once it occurs.

Why Are Children’s Ears More Vulnerable to Fireworks Than Adults’ Ears?

Children’s ear canals are narrower than adults’, which means the same sound pressure wave generates a higher intensity inside the ear canal at the point it reaches the cochlea, with research cited by paediatric audiology organisations indicating that sounds reaching an infant’s cochlea can be up to 20 dB louder than those experienced by an adult standing in the same position.

Each 10 dB increase on the decibel scale represents a tenfold increase in sound intensity. An adult standing 15 metres from a firework that peaks at 170 dB might be approaching the WHO’s upper limit for adults. A child at the same spot is not, because their smaller ear canal amplifies the pressure further before it reaches the cochlea. For infants and toddlers, this difference is clinically significant and not a minor margin that can be dismissed.

Children also have less experience to draw on when noise becomes overwhelming. An adult instinctively covers their ears, turns away, or moves further from the source. A young child typically freezes, cries, or reaches toward a parent rather than moving away from the noise. This means that protective instincts are less reliable in children, and external hearing protection needs to be in place before the display begins, not applied mid-show when several shells have already gone off overhead.

At What Age Should Children Wear Ear Protection at Fireworks?

Children of any age need hearing protection at fireworks displays, but the type changes by age: babies and toddlers under 3 must wear over-ear earmuffs because in-ear earplugs present a choking hazard and cannot be safely fitted at this age, while children aged 3 and above can wear either earmuffs or child-sized silicone earplugs depending on their comfort and the level of noise reduction required.

Infants are the most vulnerable group at a fireworks display. Their ear canals are narrow enough that sound pressure is amplified further than in older children, and they have no capacity to communicate pain or discomfort clearly. The American Academy of Pediatrics recommends that when attendance at high-noise events is unavoidable for young children, well-fitting over-ear earmuffs are the appropriate protection. Some paediatric ENT specialists advise skipping outdoor fireworks entirely for newborns and children under 6 months.

Children aged 3 to 5 can wear either over-ear earmuffs or child-specific silicone earplugs, provided an adult fits the earplugs and checks the seal. At this age, earmuffs carry a practical advantage at fireworks events: they are faster to apply, harder for a child to remove unnoticed, and deliver a higher SNR rating than most child-sized earplugs. Children aged 6 and above who are already familiar with in-ear earplugs can use fitted silicone models, provided the earplug has been practised at home before the event.

For a detailed breakdown of safety by age group, see our article on whether earplugs are safe for kids.

Which Ear Protection Works Best for Children at Fireworks Displays?

At a fireworks display, the two appropriate options for children are over-ear passive earmuffs and child-sized silicone earplugs, with earmuffs being mandatory for children under 3 and both options viable from age 3 upward, though earmuffs consistently deliver a higher SNR rating for the short, high-intensity acoustic peaks that define fireworks exposure.

The Bollsen Rooth Baby Earmuffs are designed for children aged 0 to 5, with a 28 dB SNR over-ear passive design that sits entirely outside the ear canal. There is no insertion technique required and no choking risk. The adjustable headband applies consistent pressure across the ear cups without resting on the fontanelle, which matters for newborns and young infants. At 28 dB SNR and £24.95 per pair, they fold flat for transport and the headband is machine-washable.

For children aged 3 to 12, the Bollsen Rooth Kids Earmuffs use the same over-ear passive construction with a higher-profile adjustable headband suited to older children, at 26 dB SNR and £24.95. For children aged 3 and above who prefer in-ear protection, the Bollsen Silicone Kidz+ offers 24 dB SNR at £26.95 per pair. Made from medical-grade silicone free of BPA, PVC, and latex, tested to ISO 4869 by independent German laboratories, and reusable up to 100 times, the Kidz+ is built specifically for children’s ear canal dimensions rather than scaled down from an adult mould. A small pull-tab makes removal easy for child or parent.

How Far Away from Fireworks Should Children Stand, Even with Protection?

Children should stand at least 50 to 60 metres from the nearest launch point during a fireworks display even when wearing properly fitted ear protection, a distance more than three times the 15 to 20 metre minimum recommended for adults, reflecting the additional vulnerability of children’s narrower, still-developing ear canals.

Distance and ear protection work together, not as alternatives. Ear protection reduces the sound level reaching the cochlea, but it does not eliminate it. A 28 dB SNR earmuff on a child standing close to a firework that peaks at 165 dB still delivers approximately 137 dB to the ear. Standing at the appropriate distance reduces the source level significantly before the protection takes effect, and the combination of both measures brings exposure into a range the cochlea can better tolerate.

Positioning within a public display also matters. The section of ground with the clearest overhead view is often uncomfortably close to the launch zone. Side or rear sections of most public fireworks events, which feel further from the action visually, are typically 60 to 120 metres from launch points and represent a better acoustic position for young children and infants. For similar guidance on high-dB events beyond fireworks, see our articles on ear protection for kids at concerts and ear protection for kids at sports events.

How Do You Keep Ear Protection on a Young Child During a Fireworks Display?

Children tolerate ear protection far more readily when it has been worn at home before the event: fitting earmuffs or earplugs once or twice during the days before the display removes the strangeness of the object and replaces the unfamiliar sensation with something predictable, and parents who do this consistently report it as the most effective single strategy for keeping protection in place during a live show.

This is the question that comes up in nearly every parent discussion about fireworks and hearing safety. Older children who understand that the earmuffs will stop their ears from hurting tend to cooperate readily. Toddlers are more likely to reach up and pull at something unfamiliar the moment the first burst startles them. A practice session at home, with the child seated calmly and a parent wearing their own protection at the same time, addresses this directly and normalises the equipment before the acoustic stress of the event.

For babies and very young toddlers who cannot be reasoned with, the fitting approach matters as much as the preparation. The Rooth Baby Earmuffs use an over-the-head headband rather than a tight under-chin strap, which reduces the sensation of being restrained. Fitting them while the child is already calm, before any noise has started, produces far better results than attempting to apply them mid-display after the first firework has gone off. A softly fitted hat worn over the ear cups can help prevent a determined toddler from pulling them off.

What Are the Signs That a Fireworks Display Has Damaged a Child’s Hearing?

If a child reports ringing or buzzing in their ears after a fireworks display, cannot hear normal speech clearly, or shows muffled hearing in the hours following the event, these are signs of acoustic trauma and should be evaluated by a paediatrician or audiologist within 24 to 48 hours, because prompt assessment can determine whether the change is temporary or permanent.

Temporary threshold shift is the milder form of noise-induced hearing change. The child’s hearing appears reduced immediately after the event and may recover partially or fully over the following hours or days. A persistent change that does not recover indicates that cochlear hair cells have been permanently destroyed. The distinction cannot be made at home, which is why any post-fireworks hearing symptoms should prompt professional evaluation rather than a wait-and-see approach.

Younger children who lack the language to describe what they are hearing may show different signals. A child who does not respond to their name at the usual volume, asks for the television louder than normal, or seems startled by sounds they would typically ignore in the days following a fireworks event may be experiencing some degree of post-exposure hearing change. For a detailed guide to what parents should watch for, see our article on the signs of hearing damage in children. For a broader understanding of how noise events affect children’s hearing over time, see our article on noise-induced hearing loss in children.

Fireworks are the highest-dB situation most children encounter in everyday life. At 140 to 170 dB peak sound pressure, each display delivers multiple impulse events that exceed the WHO’s 120 dB safe limit for children, and the cochlear hair cells that noise destroys do not regenerate. The right ear protection by age, combined with a safe viewing distance of at least 50 to 60 metres, reduces the risk to a manageable level. For babies and toddlers aged 0 to 5, Rooth Baby Earmuffs at 28 dB SNR are the appropriate starting point at £24.95 per pair. For children aged 3 to 12, Rooth Kids Earmuffs at 26 dB SNR and £24.95 or Bollsen Silicone Kidz+ earplugs at 24 dB SNR and £26.95 both provide meaningful protection.
