Ambulance become a critical vehicle used during the COVID-19 pandemic. Equipped with a siren, not infrequently many feel scared when they hear the sound of an ambulance passing by.
The siren is actually an additional device installed in the ambulance to make it easier for the vehicle to pass. There’s a siren reason ambulance turned on, becomes a marker asking for priority over other road users.
One of the volunteer COVID-19 ambulance drivers, Antonius, said that there are 4 types of siren sounds commonly used by ambulances. The sound of the ambulance siren will vary depending on the current situation.
“We turn on the siren so that the sick family or neighbor hears the ambulance has arrived and directs our crew to the person concerned. That saves a lot of time and may mean a lot to him who is fighting for his life with Covid.” he wrote on his personal Twitter account quoted by detikcom with the permission of the person concerned, Sunday (18/7/2021).
In a short video on the Central Java Public Relations Youtube account, there are 4 types of siren sounds issued by the ambulance. Each sound indicates a different situation.
- First, the sound of a siren resembles the sound of a railroad bar. This sound indicates the ambulance is picking up the patient.
- Second, the siren sound with a faster tempo indicates the patient is carrying a patient but the condition is not an emergency.
- Third, the sound of a siren which indicates that the ambulance is carrying a critical patient or emergency department. The sound is similar to the second, but the rhythm is faster and louder.
- Fourth is the sound of a siren which indicates the ambulance is carrying the body. His voice has a long, non-repetitive rhythm.
Meanwhile, quoted from the Ambulance website, this car has five types of sounds for the siren, namely yelp, phaser, wail, horn, and hi-lo. Yelp is used when the ambulance is at an intersection, wail is used when the ambulance is on a straight road.
Then hi-lo is used as a blend to get attention effectively. Meanwhile, the new horn is used as a horn if the sounds of other sirens fail to get the attention of road users.
