Imperceptibility is the quality of being impossible or difficult to perceive. π This could be through sight, sound, smell, or any other sense. Something with imperceptibility is so faint, small, or well-hidden that it escapes notice. Think of a ninjaβs movements or a nearly invisible watermark. It's often a desired trait in stealth technology or camouflage. It's also used to describe subtle changes that are hard to detect.
