Yes, it is highly recommended for babies to wear noise-canceling ear defenders or soft earmuffs during a flight in 2026. While the primary concern for many parents is "airplane ear" (pain from pressure changes), ear defenders are actually more effective at protecting a baby's delicate hearing from the high-decibel engine noise, which can peak at 110-120 dB during takeoff. Muffling this ambient roar helps keep the baby calm and can encourage better sleep. For the pressure changes themselves, ear defenders provide a slight physical barrier, but they do not equalize pressure; for that, doctors suggest breastfeeding, bottle-feeding, or using a pacifier during takeoff and landing to trigger the swallowing reflex. In 2026, specialized infant headphones designed with pressure-venting technology have become popular, providing both sound protection and a more comfortable environment for the child’s inner ear.
