Abstract

An elevator installation for a building includes an elevator controller to move from one floor to another floor and a plurality of sensor units. Each sensor unit is located on a floor and configured to generate an electrical signal that is indicative of a noise level in its vicinity. A processing unit analyzes received electrical signals to determine if there is an increased noise level on a floor on which the sensor unit generating that electrical signal is located, and to detect that a source of noise moves to distinguish it from a non-moving source of noise that may also be responsible for an increased noise level, and generates a control signal for the elevator controller that is indicative of the floor with the increased noise level. The elevator controller in response to the control signal causes the elevator car to move to the floor with the increased noise level.
