Abstract

The invention relates to a method for controlling an operational parameter of a flotation cell (1) that comprises a housing and that is used to separate amounts of solid particles in a suspension (2). The individual sound signal (50) of the flotation cell (1) that is produced during operation is received in the flotation cell, a characteristic characterising the operational parameter is extracted from the received individual sound signal (50), and an adjustable variable (55) for controlling the operational parameter is determined from the extracted characterised characteristic.
