5 Best White Noise and Sound Masking Machines for Better Sleep in 2025

After our look at sleep tracking wearables, we now explore the best options for Sleep Environment.

White noise and sound masking machines have become essential tools for creating optimal sleep environments. These devices work by producing consistent ambient sounds that mask disruptive noises like traffic, neighbors, or snoring partners. By filling the auditory environment with steady, non-intrusive sound, they help your brain filter out sudden noise changes that typically trigger arousal during sleep cycles.

The science behind sound masking is straightforward: sudden noise changes create contrast that alerts your brain. White noise reduces this contrast by providing a constant acoustic blanket. Studies show that consistent ambient sound can reduce sleep latency (time to fall asleep) and increase overall sleep quality, particularly in noisy urban environments.

Our technical analysis evaluated machines based on sound quality, variety, volume range, portability, and power options. We prioritized devices with non-looping audio tracks, as repetitive loops can become noticeable and counterproductive. The following five machines represent the best options currently available for creating peaceful sleep environments in 2025.
