A siren typically uses electrical energy to produce sound waves and generate the loud alert or warning sound. Some sirens may also utilize pneumatic energy through compressed air systems.
A siren goes through electrical energy to sound energy transformation. When electricity is supplied to the siren, it vibrates to produce sound waves in the air.
The energy transformation for a siren involves electrical energy being converted into sound energy. An electric current passes through a coil in the siren, creating a magnetic field which causes a diaphragm to vibrate and produce sound waves. This process allows the electrical energy to be converted into audible sound.
depends on the siren... but about 4-10kW is average
The Doppler effect causes the pitch of the siren to change as it moves past Mary. As the siren approaches, the sound waves are compressed, resulting in a higher pitch. As it moves away, the sound waves are stretched, resulting in a lower pitch. This change in frequency creates the perception of the siren's pitch changing.

It starts out as electrical, then changes to acoustic(because you can hear it) and radiant(because it lights up). It might also later become thermal energy(unwanted energy) if it is on for a long period of time because the light will start to get hot.
Sirens is the plural of siren
It depends on the circuit that controls the siren. The circuit may be designed for only a 100 watt device and by doubling the current through the circuit, the circuit may be destroyed.
An electric siren is based on the principal of electrical energy and signals being converted into sound. Electrical inputs enter the a speaker through circuitry. In turn these signals are vibrate the air through the speakers function. Electrical sirens are in fact speakers, but there are mechanical sirens which use motion to drive the sound making assembly.
Fire department siren.
Energy transformed by the means of energy transformation.
