Érzékeltesse

Érzékeltesse is a term sometimes used in theoretical or linguistic discussions to denote the property or potential for an object, signal, or event to be perceived by a sensory or measurement system. In standard Hungarian, the more common term for this concept is érzékelhetőség, which covers the general idea of detectability or perceptibility. Érzékeltesse thus appears mainly in theoretical discourse, model descriptions, or as a stylistic variant.

The concept encompasses both human perception and machine sensing. Perceptibility depends on the characteristics of the stimulus (such as intensity, duration, modality, and spectral content), the state of the observer or sensor (attention, adaptation, sensitivity), and the surrounding environment (noise and interference). In psychophysics, perceptibility is often quantified through detection thresholds and psychometric functions that relate stimulus strength to the probability of detection. Signal detection theory provides measures like d’ (d-prime) and criterion to describe detection as a probabilistic process rather than an absolute event.

Applications of the notion include the design of safe and accessible interfaces, displays with appropriate contrast and salience, reliable audio-visual signaling, and imaging or diagnostic protocols where a stimulus must be perceived under varying conditions. Limitations arise from subjective variability across individuals, context effects, and sensor limitations. While not universally standard in Hungarian, érzékeltesse offers a concise way to discuss the inherent detectability of stimuli within theoretical or cross-disciplinary work.
