häire

Häire is an Estonian word meaning disturbance, fault, or malfunction. It is used to describe disruptions that impair normal operation of devices, systems, or processes, as well as medical or psychological disorders.

In technology and engineering, a häire refers to a fault or disturbance in equipment or networks, which can affect performance and reliability. Common contexts include electrical faults, sensor malfunctions, and interference in communications. In public safety, the term appears in compound forms such as häirekeskus, the emergency call center that coordinates response to incidents, or häireteade, an alarm notification.

In healthcare, häire denotes a disorder or abnormal functioning of an organ system, and is used in phrases such as vaimse tervise häired (mental health disorders) or elundite häired (disorders of organs) in clinical descriptions. In everyday language, häire can also describe a disturbance in daily life, such as a noise disturbance or an interruption in a routine.

The word forms part of many Estonian administrative and technical terms and is an integral part of medical, technical, and emergency-response vocabulary. While it is primarily used in Estonian, the concept it represents—disturbance, fault, or disorder—is a common idea expressed in many languages with corresponding terms used to describe faults in equipment or health conditions.
