Which characteristic do not determine the effect of noise on task performance?

Luminance

The correct answer is Option (2) → Luminance

Three characteristics of noise have been found to determine its effect on task performance, namely, intensity, predictability, and controllability of noise.

Explanation:

• Intensity refers to the loudness of the noise, which can significantly affect task performance.
• Predictability relates to how anticipated or expected the noise is, influencing how it disrupts concentration.
• Controllability refers to whether the individual can influence or manage the noise, which can also impact performance.
• Luminance, on the other hand, pertains to the brightness of light and is not directly related to noise or its effects on task performance.
