The sound of a siren was invented by John Robison, a Scottish inventor who developed the design in the late 18th century. The siren is a mechanical device that produces a loud, piercing sound by passing air through a rotating disk with holes.
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.
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.
An approaching siren demonstrates the Doppler effect as the sound waves are compressed and have a higher frequency, causing the pitch to sound higher. This occurs because the sound waves are "bunched up" as the source moves closer, altering the perceived frequency of the sound.
The sound of a siren is typically described as loud, piercing, and shrill. It is designed to grab attention and signal an emergency or warning.
A horn or a siren can produce a loud sound.
A siren makes a sound and that's why it must be a sound source.
The sound waves in front of the siren bunch up, and those behind the siren spread out.

Yes, they make a sound like a siren. Hence the name "Siren".

The word "siren" has a short vowel sound. The "i" makes the short /ɪ/ sound in this word.
