Fresh Rankings: Meg Updates the Best Sound Machines for Sleep and Rest
By David Miller
The average shopper asks for white noise, but true white noise is rarely what a light sleeper needs. White noise distributes energy equally across every frequency between 20 Hz and 20,000 Hz. The result sounds harsh, reminiscent of television static or an escaping blast of high-pressure steam. Its high-frequency energy can cause ear fatigue over eight hours.
The real debate in the sleep lab centers on pink noise vs brown noise. Pink noise drops energy by 3 dB per octave as frequency increases. This mimicry of natural rainfall or rustling leaves aligns closely with human hearing curves, making it exceptional at dampening sudden conversational bursts.
Brown noise drops energy by 6 dB per octave, pushing acoustic power down into the low-frequency basement. It sounds like a distant waterfall or heavy ocean surf. Meg’s field notes single out brown noise as the ultimate snoring sound blocker. Because an airway obstruction produces low-to-mid frequency vibrations, the heavy low-end shelf of brown noise absorbs the acoustic peak of snoring far better than higher-frequency white noise ever could.
