Life Sounds 440 White Noise, Infant Sound Machine
The LifeSounds is made by Marpac Company in the USA. It is intended for newborns. The first thing you’ll notice is the housing is the same as the Marpac DS-600. But this unit offers different sounds, thus it has a different sound board in it.
The volume is controlled by a slider switch on the front bottom of the unit. There are only three buttons on the unit. On/off, sound selector and a 60 minute timer option.
The sounds are:
Womb
Heartbeat
Lullaby
Surf
Rain
Brook
Although there is no “white noise” sound selection white noise is just a type of noise, not a specific sound. We found that the ‘rain sound’ is a good white noise equivalent. The unit runs off of an included wall plug or 4 AA batteries.
The sound quality is fair to good. At high volume we did notice some vibration noise from the rear of the unit. This was coming from the battery compartment, so we suggest putting batteries in it to keep the battery springs from vibrating.
