What is pink noise?
A very quiet sleep environment is unfamiliar to babies and may make it harder for them to fall asleep. While in the womb, babies are enveloped in sound, mum’s voice and heartbeat, the rhythmic movement of the digestive system, the oceanic whoosh of breathing and arterial blood flow, and the filtered sounds of the world outside. Pink noise can be found in a heartbeat, the roar of the ocean and the fluctuations of the tide. Every day as we live and breathe, like babies in the womb, we are enveloped in pink noise. Pink noise aids in falling asleep faster, deeper and for longer as it provides baby with a comforting and familiar and more natural background noise in comparison to other noises or no noise at all.
Why do the two pink noises sound identical?
While both are in the pink noise spectrum, one applies a low-pass filter, reducing frequencies greater than 1,000Hz. Infant ear canals are more sensitive than ours and they amplify high frequencies. In other words, what is a negligible difference to us is a big one for babies. The closest comparison is adults with tinnitus, who are also sensitive to high frequencies.
Why red light?
Research has shown that compared to exposure to blue light, which significantly suppresses melatonin, red light exposure has little to no effect on melatonin suppression, the hormone which signals to the body it’s time to start winding down. Red light is also minimally stimulating, in other words, by using red light as a night light, infants (and adults) can drift off in the same way they would in a completely dark room and makes re-settling easier after night-time awakenings.
Why pulsing light?
The rhythmical light waves encourage slow, deep breaths to relax the user ready for sleep. The pulse settings are set to mimic breathing rates. The first, faster pulse reflects baby’s resting breathing rate ~20 breaths per minute (bpm), helping to induce sleep in infants. The second, slower pulse mimics your resting breathing rate, helping you to drift off!
Why is the audio quiet?
We have followed best practice guidelines and limited the maximum volume to 50db, in line with neonatal wards. At this level, the sounds are audible and brain waves pick up on them, but they do not disturb once asleep.
Why are there 3 brightness settings?
With three different levels of brightness you can choose the level you prefer. Following best practice guidelines, we have limited the maximum brightness settings to ensure that the light is comforting and relaxing but does not disturb once asleep.
WARNING: You should ensure the Dreammaker™ sleep aid and cable is placed at least 3ft away from baby’s cot/bed.
