2. White Noise Machines

White noise machines produce a consistent soundscape that masks disruptive noises like traffic, barking dogs, or snoring. This steady hum helps calm the mind and signals your brain that it’s time to sleep, reducing the chances of waking up during the night. Unlike basic phone apps, dedicated devices such as LectroFan and Marpac offer a range of options—including pink noise and nature sounds—for a more personalized experience. Their portability and reliability make them a popular choice for restful sleep.
