Earmuffs can be used for hearing protection and noise reduction, which can help ensure your baby (and you) can rest peacefully on a longer flight. Earmuffs can also potentially reduce discomfort caused by changes in air pressure, so be sure to pack them along in your carry-on or Pack.

Ear defenders (or noise-canceling earmuffs) are highly beneficial for children on planes as they address two primary stressors: noise and sensory overstimulation. Aeroplane cabins can reach noise levels of up to 80–85 decibels, which is equivalent to a loud vacuum cleaner running continuously. For infants and toddlers with smaller ear canals, this sound pressure is even more intense and can lead to fatigue or "meltdowns." While they do not prevent "airplane ear" caused by pressure changes—swallowing or using specialized pressure-regulating earplugs like EarPlanes is better for that—defenders create a quiet sanctuary that helps children sleep and protects their sensitive hearing from long-term damage. They are also invaluable for children with autism or sensory processing sensitivities who might find the sudden bursts of noise from the intercom or engine roar distressing.
