In this phenomenon,zawgySan posted on reddit. Zawgy who is riding in the 2017 type Subaru WRX gets a car to go to work every morning, but recently when I got in the car and got the gear back in the morning, an alarm from a neighbor's house The mystery phenomenon that the sound is ringing has come to be said to have occurred. Zawgy wrote that the alarm sounds resonate with tremendously loud sounds, and it is not at a very negligible level.


This phenomenon began on December 11, 2017 (Monday). At first it was zawgy who thought that it might be a coincidence, but a few days, from the point where I noticed the phenomenon that the alarm sounded around the timing when I got into the car zawgy was attacked by embarrassment, Just think about the cause.

The first thing I suspect was that the time of going out and the time of the alarm device set by the neighbors coincided coincidently. However, zawgy rides a car every morning from 8 o'clock to 8:15, but its timing varies, so if the theory that the alarm sound set at a fixed time is accidentally sounded Thing.

Next, zawgy's doubt is "The theory that the alarm device starts by putting the gear in the back." In fact, when I got into the car and did not operate anything, nothing happened, but the moment I put the gear in the back, the warning sound began to raise with a sharp sound "Wow ~ Wow ~" That's right.

It is a place I'd like to say that this is one crash, but it is inevitable that I will suffer from the same situation in the future as I do not know the causal relationship between alarm sound and back gear. So, in order to clarify this mystery, zawgy asked reddit for help.

Then, in response to this writing, a lot of rigid and confused comments have been sent. Zawgy says, "I'm always late in time, so I wait for a while after the alarm tone, wait for a while, and see the situation of my neighbors I do not have the time to make sure, but I know that the alarm sounds stop ringing within about 10 seconds from the beginning of the beep so it is probably the person who was sleeping on the second floor comes down to the first floor and is stopping Wow "answer.

Zawgy commented that "This car has not been played at all and it is still being delivered" to the comment "Since the exhaust sound is noisy, the sensor of the alarm device is reacting." In other words, there is no possibility that alarms are responding to explosions like a remodeled car. Rather than me, zawgy says that the alarm tone begins to ring is "the moment of putting the gear in the back" and the exhaust sound apparently is irrelevant as it is not the moment of starting the engine.

Regarding the exhaust sound, "Vehicles that respond to the sensor of the alarm device may be reacted by changing the frequency of the exhaust sound as the engine turns down with moving the gear in the back" is also given. Nevertheless, it is a question where the sound quality will change dramatically with the muffler in the normal condition.

I got an idea that "Try putting gears in the back without putting the engine on."

For the comment "Does your car's security sensor get confused with the neighbors' alarm system?" Zawgy says, "Although my car has no security sensor, security cameras Although it is mounted, although it is not thought that the camera is emitting some kind of signal. " The mystery will deepen.

Also, "Users may write tapes on the backlight and try again, maybe the flicker of the LED lamp is acting on the alarm system sensor". In response to this, Zawgy commented, "I will try it out and shoot it on a video and upload the results." However, information on that Subaru WRX's ride on which Mr. zawgy is riding is not an LED but an incandescent light bulb has also been sent, so the possibility of this Sen also seems to be light.

Zawgy says to the idea that "If you put in the back when you park the car and can go out in the morning to make it move forward," zawgy says, "Yes, this may solve the situation, but on the other hand I want to clarify the scientific background of why such a thing is going on. "

With such a feeling, two days have passed since the post in the state that zawgy's question is not able to find a definitive answer. From now on, zawgy will verify the ideas gathered here, and if possible we will film and shoot the movie, so I definitely want to know the result.
