In the womb babies are surrounded by sound; mom’s heartbeat, breathing, blood flow, plus the filtered sounds of the world outside. So, sound for them can be very soothing.
From our work with the sleep lab, we found that low frequency sound is more efficient than higher when trying to relax. Pink noise is the most balanced and natural of all sounds – it’s like soothing background noise. It encourages deeper sleep whilst enhancing slow brain wave activity which is critical for memory and learning efficiency.
This pink noise is so important, the Dreammaker includes two settings. Standard pink noise the whole family can hear. And low-pass filtered pink noise with a 6 dB per octave roll-off – in simple terms, this setting mimics the exact frequency that sound would reach foetal ears. Mimicking how they would feel in the womb.
