The Best Sleep Noise Machine

Available only from Hammacher Schlemmer, this is the high fidelity sleep sound machine that provides the best night’s sleep possible. Unlike lesser models that only generate white noise, this unit emits pink noise—an engineered sound similar to white noise but with more balanced frequencies. A study conducted at Northwestern University found that adults exposed to pink noise when asleep experienced a reduction in brain wave activity, resulting in a much deeper and restful slumber. It generates professional quality audio via Bluetooth from an enabled device or using the included Micro SD card that comes pre-loaded with pink noise, low rumbling brown noise, white noise, and nature sounds. With a built-in volume control and access to free apps including tinnitus therapy and sleep sounds for infants. During the day it can be used as a 30'-range Bluetooth speaker or operated as speakerphone using its integrated microphone. Plugs into AC or operates using a rechargeable battery; a full-charge provides up to eight hours of power.8" L x 2 1/2" W x 2 1/4" D. (1 1/2 lbs.)
