An environment control system (1) for controlling the environment in an area (50), the area (50) comprising a plurality of sub-areas (50a1-50c5), the environment control system (1) comprising: a sensor unit (20) for generating a sensing signal pertaining to activity in the area (50), the sensor unit (20) comprising an activity type determination unit (22) for determining an activity type for each sub-area (50a1-50c5) based on the generated sensing signal for the area (50), a sound generating device (30) adapted to generate sound (32) with a varying sound property individually in each sub-area (50a1-50c5), the varying sound property having a first frequency, a light generating device (40) adapted to generate light (42) with a varying light property in each sub-area (50a1-50c5), the varying light property having a second frequency, a control unit (10) adapted to control the sound generating device (30) and the light generating device (40) independently for each sub-area (50ai-50c5), depending on the determined activity type for the corresponding sub-area (50a1-50c5), wherein the ratio between the first and the second frequency is an integer. |
