SoundOff uses pink noise technology to mask noise. What is pink noise? Pink noise is similar to white noise, only better. It’s smoother than white noise. It is the soothing sounds in nature like wind, rain or a waterfall. Pink Noise is a calming sound and studies show it gives you faster better sleep. Because pink noise is so soothing it not only does not interrupt your sleep, it can actually help you sleep sounder. And you won’t hear snoring or other annoying sounds. We Promise.
Again, studies show pink noise gives you faster better sleep.

Study one title
Pink noise: Effect on complexity synchronization of brain activity and sleep consolidation.
Methodology and conclusion:
In this study we hypothesized that steady pink noise is able to change the complexity of brain waves and have significant effect on improving sleep quality. First, we carried out a brain synchronization test in which electroencephalogram (EEG) signals of 6 subjects were recorded. The whole experiment procedure was divided into 5 blocks in the alternative process of 10-min quiet and 10-min pink noise. After analysis we found the complexity of the EEG signals decreased with the introduction of pink noise exposure, showing the brain waves tended to synchronize with the pink noise induction and reach a low level. For the sleep quality experiment, 40 subjects were recruited for the nocturnal sleep experiment and 10 participants were chosen for the nap test. Each subject slept for two consecutive experimental periods, of which one is pink noise exposure and one is quiet. For both nocturnal sleep and nap tests, the results in the pink noise exposure group showed significant enhancement in the percentage of stable sleep compared to the control group based on an analysis of electrocardiography (ECG) signals and cardiopulmonary coupling. This study demonstrates that steady exposure to pink noise has a significant effect on reducing brain wave complexity and inducing more stable sleep, improving sleep quality.

Study two title
Sleep induction effects of steady 60 dB pink noise.
Methodology and conclusion:
The effects of 60 dB steady pink noise on sleep induction were studied. Two experiments were conducted. First, 10 night-sleep polygrams of a young male subject were recorded consecutively as controls. Five night polygrams of the same subject were then recorded with exposure to steady 60 dB pink noises. Second, polygrams of four students were recorded using the same pink noise exposure as the first experiment. Polygrams of the same subjects with no pink noise were also recorded as a control. Pink noise exposure tended to shorten the time it took to achieve sleep. It took less than half the time for the pink noise subjects to achieve to sleep than the control subjects. The steady 60 dB pink noise exposure made sleep induction easier.
