For both nocturnal sleep and nap tests, the results in the noise exposure group showed significant enhancement in the percentage of stable sleep time compared to the control group based on the analysis of electrocardiography (ECG) signal with cardiopulmonary coupling approach. Bad habits exist, and wikipedia apparently is not always correct. Even a wikipedia page refers to SPL and SWL as being valid descriptors. I noticed that Waves has a discount on the X-Noise and Z-Noise plugins. SPL is widely used for 'sound pressure level', but these characters could as well describe 'sound power level' although a few decades ago sound power level was abbreviated in the US with PWL.

Each subjects slept for two consecutive experimental periods, of which one is pink noise exposed and the other is quiet. Whats the difference Discussion in Backline started by ahjteam, Jun 18, 2011. For the sleep quality experiment, 40 subjects were recruited the group of nocturnal sleep experiment and 10 participants were chosen for nap test. Each particle in the fluid moves back and forth about one position. There is energy transport (the disturbance propagates), but there is no net transfer of mass (no convection). After the complexity analysis of fractal dimension, we found that the complexity of the EEG signals decreased with the introduction of the pink noise exposure, showing the brain waves tended to synchronize with the pink noise induction to reach a low level. Z 5.2 SOUND WAVES The sound disturbance travels in space. The whole experiment procedure was divided into 5 blocks in the alternative feeding process of 10-min quiet and 10-min noise. From what I can tell from advertising, Z Noise is the superior product and is listed for 99 X Noise is the older product, yet priced around 300. First, we carried out the brain synchronization test in which electroencephalogram (EEG) signals of 6 subjects were recorded. The frequency weightings used in sound level meters are often related to the response of the human ear, to ensure that the meter is measuring pretty much. In this study, we hypothesized that steady pink noise is able to change the complexity of brain activities into a characteristic level and it might have significant effect on improving sleep stability. Frequency Weightings - A-Weighted, C-Weighted or Z-Weighted The human ear responds more to frequencies between 500 Hz and 8 kHz and is less sensitive to very low-pitch or high-pitch noises.
