For the past 50+ years, Yoga Sleep has sold millions of Dohm sound machines bringing the simple joy of natural fan-based sound worldwide. If you love sleeping with a fan on to fall asleep, our fan-based white noise solution is perfect for you. The Dohm creates the soothing ambient sounds of rushing air, without the disturbance and cooling effects of actual moving air. This noise-canceling natural sound machines replicate the constant “whirring” of an air conditioner or fan in a convenient, portable unit. This simple yet effective invention is easy to use and lacks the irritating looping effects of digital sound machines. All of the Dohm sound machines have been hand-assembled in the USA since 1962.
