What would an airplane album sound like? Silence, sort of. More technically, the sound from the airflow and aircraft engines that passengers hear inside the cabin is pink noise, white noise’s low‑pitch cousin. Like a deep, continuous exhale, its ambient acoustics can actually have a calming effect. Think babbling brook, crackling fireplace, or rain shower – all of which you will find in Amazon Alexa’s relaxing sleep sound library, alongside airplane noises.
Studies have shown that pink noise can improve sleep quality, concentration and even memory. It’s why there are apps, albums and videos that simulate the conch croon of the cabin. One YouTube video depicts nothing but a window‑seat view of a wing rocking against a starry sky as clouds drift by like tumbleweed. The 10‑hour video has been watched – or listened to – over 3 million times, and it has the benefit of being more relaxing than the average level of noise in an actual airplane cabin, which produces sound levels between 85 and 105 dB.
