Häiriöherkät

Häiriöherkät is a Finnish term used to describe entities that are highly susceptible to disturbances or interference. The exact meaning depends on the field, but the core idea is a low tolerance for external perturbations, whether in physical systems or in human perception.

In engineering and electronics, häiriöherkät järjestelmät are systems whose performance degrades readily in the presence of electrical or electromagnetic interference, noise, or other disturbances. Examples include sensitive analog circuits, precision measurement devices, and wireless or data links operating in noisy environments. Mitigation strategies include shielding, careful layout, filtering, error-correcting codes, and robust design practices to improve resilience.

In psychology and education, the term is sometimes used informally to describe individuals who are especially sensitive to environmental stimuli or social situations. This usage overlaps with concepts such as sensory processing sensitivity or high emotional reactivity. It is generally viewed as a trait on a spectrum rather than a disorder. People described as häiriöherkät may benefit from predictable routines, calmer environments, and opportunities to recover from overstimulation.

Critique and context are important: labeling someone or something as häiriöherkät can obscure normal variation or risk pathologizing common sensitivity. Clear, field-specific criteria and concrete mitigation or support strategies improve usefulness and accuracy.
