Scale attenuation effect
Did you know?
In statistics, a floor effect (also known as a basement effect) arises when a data-gathering instrument has a lower limit to the data values it can reliably specify. This lower limit is known as the "floor". The "floor effect" is one type of scale attenuation effect; the other scale attenuation effect is the "ceiling effect". Floor effects are occasionally encountered in psychological testing, when a test designed to estimate some psychological trait has a minimum standard score that … WebWhat’s the problem here? Scale Attenuation Effects When scores cluster at either end of the scale, we have scale attenuation effects: Floor effect: low scorers are clustered Ceiling …

The broader responses decrease scallop loss, which makes sense since signals in adjacent cells will overlap at higher amplitudes for broader responses thereby minimizing scallop loss. The weighting functions also affect the amplitude of the sidelobes.
WebThis property is used to enable or disable the listener focus system. If True, then the sound will check to see whether it is in or out of focus and apply the various scaling factors accordingly. If False, then the sound will simply behave according to its usual attenuation, distance, and priority settings.
