With a Dohm-DS white noise machine, you will no longer have to whisper and tiptoe around when your child is sleeping! Also useful when siblings share rooms or have different bedtime schedules. This white noise machine can be placed inside the bedroom, or outside the bedroom door to provide generalized white noise in the quiet sleeping area. The Dohm-DS is also useful for office privacy and sound masking. If you do not want someone to hear conversations inside a room, you should place the Dohm-DS unit directly outside the room so people will only hear the white noise, not the conversation. White noise machines have also been effective for cubicle privacy, especially when speech privacy is needed.
