wahrnehmbar

Wahrnehmbar is an adjective in the German language used to describe something that can be perceived or detected by human senses or by measurement instruments. In everyday language it refers to phenomena that can be experienced or observed; in scientific contexts it denotes signals, events, or data within the range accessible to perception or instrumentation.

Etymology: from wahr (true, real) and nehmen (to take). The compound aligns with the sense of taking information from the environment through perception.

In psychology, neuroscience, and sensory research, a stimulus or phenomenon is called wahrnehmbar if it can produce a perceptual experience. The term also appears in discussions about the limits of perception, for example stimuli at the edge of human sensitivity or inaudible frequencies outside the auditory range or undetectable infrared wavelengths.

In philosophy and epistemology, Wahrnehmung is central; wahrnehmbare Vorgänge are considered the objects of empirical knowledge. The term is used to distinguish what is accessible to sense from things that are not directly perceivable, and to examine issues like illusion, bias, and measurement error.
