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.

WebSep 3, 2024 · The scale between the 2 numbers reflects the impact of the PPE’s fit on its NRR value. A wider range means more variation in protection, whereas a small range results in a more consistent fit. For example, over-ear headphones should generally have a smaller range (and higher maximum NRR) than earbuds. WebNov 26, 2024 · A floor effect occurs when a measure possesses a distinct lower limit for potential responses and a large concentration of participants score at or near this limit (the opposite of a ceiling effect). Scale attenuation is a methodological problem that occurs whenever variance is restricted in this manner.

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".
