A police car siren or an ambulance from a distance. Vintage recording.
Berlin Turkish market crowd with shouting and calling, movement and activity. Distant siren midway
Aggressive whirling siren
Fire engine with siren passing by, some background traffic
Fire engine siren, medium distant perspective, moving away.
Fluctuating low end drone and high pad
Deep and thick tone modulations
Alien warning alarm,quick screech
Park ambience, bird and ducks, distant sirens and rustling
