How to Sleep with Earplugs on a Plane | In-Flight Noise Fix

For the full breakdown, see our best Earplugs For Sleeping On Plane guide.

Cabin hum, crying babies, and seatmate chatter make airplanes one of the hardest places to fall asleep. Earplugs are the simplest fix — but only if you wear them right. The difference between a restless flight and real rest comes down to choosing the right attenuation, inserting plugs properly, and pairing them with a few deliberate habits. Here is the exact routine that works on long and short flights alike.

Choosing the Right Earplugs for a Plane

Aircraft cabin noise typically sits around 80–85 decibels during cruise. You need earplugs with an NRR (noise reduction rating) between 28 and 32 decibels — enough to cut the drone without blocking important sounds or causing discomfort. Higher attenuation is rarely necessary and can make the plugs feel too firm after a few hours.

Foam earplugs are the standard choice: they expand to fill the ear canal and offer the best seal for most people. Silicone earplugs are a solid alternative if your ear canals are oddly shaped or you find foam plugs uncomfortable after an hour.

How to Insert Earplugs Correctly (The Step That Matters Most)

Earplugs only work if they create a full seal. Half-inserted plugs let noise leak in and defeat the purpose entirely.

For foam earplugs: Roll the plug between your thumb and fingers into a thin, tight cylinder. Reach your opposite hand over your head, pull your ear up and back to straighten the ear canal, then insert the plug deeply with a gentle twisting motion. Hold it in place for 30–40 seconds while the foam expands. When it’s seated correctly, you should notice a sudden drop in ambient noise and the plug should feel snug but not painful. If it slowly works its way out, you didn’t roll thin enough or hold long enough.

For silicone earplugs: Choose the size that matches your ear canal — most brands include multiple sizes in one pack. Gently press and rotate the plug into the ear opening until it forms a flush seal. Silicone does not expand, so the fit must be correct from the start.

Insert plugs before takeoff, not after the plane gets noisy. Once the cabin fills with engine roar and chatting passengers, the loud environment makes it harder to tell if the seal is good. You will also sleep through the ascent more easily with the plugs already in.

Building Your Complete In-Flight Sleep Kit

Earplugs alone rarely deliver deep sleep on a plane because light and motion also disrupt rest. Combine them with a sleep mask that blocks all light — the darker you make your environment, the faster your melatonin rises. Choose a window seat so you can rest your head against the cabin wall and minimize disturbances from passengers needing the aisle. If the noise is still noticeable, add over-ear noise-canceling headphones over the earplugs for extra dampening; this combination is effective but not a substitute for staying aware of safety instructions.

To help your body wind down, limit phone or tablet use at least 30 minutes before you plan to sleep. Avoid heavy meals, caffeine, and alcohol in the hour before sleep — they disrupt sleep quality and can make earplugs feel more uncomfortable if your sinuses swell. If you struggle to relax once you are settled,

Keep your seatbelt fastened over the blanket or clothing while you sleep so you do not need to wake up if the seatbelt sign comes on, and use a travel pillow to keep your head from drooping forward.

Common Earplug Mistakes That Ruin Plane Sleep

Even with good earplugs, a few common errors can ruin your chance of rest. Using plugs with excessive NRR makes them too firm and uncomfortable for a long flight, causing you to remove them after an hour. Inserting foam plugs too shallowly leaves a gap that lets in the very noise you are trying to block. Reusing disposable earplugs for more than one flight introduces dirt and bacteria and degrades the foam, making the seal unreliable. And failing to bring a backup pair means a single lost plug can force you to deal with the noise unprotected for the rest of the trip.

Clean reusable earplugs after each flight with warm water and mild soap and replace them every three to six months. Disposable foam plugs should be discarded after a single use. If you need to hear crew announcements or safety instructions, loosen or remove one earplug rather than trying to hear through the full attenuation.
