Beloved by generations since 1962, the Dohm is the original white noise machine. The Dohm model features our fan-based natural white noise producing our signature sound – the soothing ambient sounds of rushing air, without the disturbance of actual moving air or other irritations. With two-speed options for adjustable tone and volume, the Dohm makes it simple to create a personalized sound environment, excellently masking background sounds and allowing for better sleep, office privacy, effective soothing for kids and babies, and calming for sound-sensitive dogs. Powered by an 8-foot 120V AC plug (for domestic use only), just plug in the Dohm, flip the switch to high or low, then rotate the cap and collar to find the best sound for you. Let the noise-masking magic happen for a natural sleep aid, office privacy, baby soothing, tinnitus relief, respite from noisy snorers and unfamiliar hotel rooms, and a relaxing calming balm for barking dogs.
