Sirens is the plural of siren
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
