The sleep-inducing magic of a Yogasleep sound machine makes falling asleep as easy as pushing a button. Dohm Classic is the original sound machine, first invented by Yogasleep in 1962 and beloved by generations since. The Classic features our fan-based natural white noise, with two speed options for widely adjustable tone and volume. Just flip the switch to high or low, rotate the cap and collar to find the best sound for you, then let the noise-masking magic happen. By adjusting the speed and sound openings, you will customize the volume and tone to find a soothing white noise that's ideal for you. Features an 6' cord, and comes in four color options: white, black, camo, gray, pink and tan. Give sleep a chance! Note: For all users, we recommend placing our sound machines at least three feet (3') away from the sleeper’s head. At a distance of 6.5 ft, we measure the dB level of the Dohm’s loudest setting at 52.5 dB and of our lowest setting at 41.5 dBA
