Noise that is produced by combining sounds of different frequencies together is called white noise. Since it contains all frequencies, white noise is used to mask other sounds. When two or three people talk, our brain can distinguish the sound of a particular person. But if a crowd cheers in a stadium, no individual voice can be identified. That’s white noise and is most effectively used in the emergency siren.
