The effect of the screen-induced turbulence on the average noise level behind the screen is therefore negligible.
This response variability can be used to estimate the amount of so-called internal noise—that is, noise that is not present in the stimulus (such as random dynamic dots on the screen) but in the participant’s brain.
A theory of wind noise reduction is developed and leads to a better understanding of the relative contribution of wind noise generated at the surface of the screen and wind noise generated by flow through the screen.
It is concluded that where the average ambient noise levels are 50 dB(A) in a school testing environment and noise levels do not significantly affect the results the explanation for screen failures must lie elsewhere.

Since a smart watch is put on the wrist, the device should be small and unobtrusive.
The watch system shall be such that the efficiency of watch-keeping officers and watch-keeping ratings is not impaired by fatigue.
Results suggest that it will be possible to detect whether people are glancing the watch, but not where on the screen they are looking.
