In the case of auditory warnings, Gray (2011) has designed an auditory looming warning, whose intensity increased as the distance between the driven vehicle and the lead vehicle decreased, to convey information concerning the urgency of the potential collisions with the lead vehicle to the driver.
There were 12 trials in each combination of head position (forward, turned to left, and turned to right) and vibrotactile warnings (low intensity on hands, high intensity on hands, low intensity on waist, and high intensity on waist).
In the field of research on auditory warnings, increasing the intensity of a warning sound can produce an impression of a sound-emitting object approaching the observer (see Shaw et al., 1991).
What really came without warning was the intensity of Gabriel's reaction.
The sound directivity, frequency of emission and intensity of warning sound systems will guarantee their efficiency and limited noise impact.
If monitoring intensity and warnings are associated with higher sanction intensity, it would be difficult to identify the effect of actual sanctions without information on monitoring and warnings.
For instance, dynamic tactile warnings (varying in their intensity and/or location) can potentially be used to convey meaningful information to drivers.
And under International Civil Aviation Organisation regulations, any structure over 45 metres tall on a flight path or near an aerodrome must be fitted with a medium-intensity aircraft warning light.
For the Swiss case, these authors argue that monitoring intensity and warnings may have a positive effect on the exit rate from unemployment, independently of actual sanctions being imposed.
The graphics show clearly that the intensity of warnings per person increases significantly at the 5% significance level due to e-Medikation in all age groups.
