Electric cars unintended consequences

[steve_bank]

In the news electric cars have a higher rate of collision with pedestrians than gas cars.

Apparently people rely on n audio key when walking. Added to it is the prevalence of people walking while on a wireless device. The cars are too quite.

Electric car makers are adding external speakers that will emit a sound when below a certain speed or breaking to alert walkers. It is at slow speeds for situations like parking lots.

Can I get my EV make some sort of Star wars sound effect? Maybe like General Grievous' monocycle? Or like a Star Wars tie fighter? Or perhaps Monty Python style clopping coconuts?

That would be cool if you could program the "run tone" of your choice into your car.
The possibilities are endless.

I drive a twelve tonne refrigerated truck. It's incredibly noisy - the refrigerator unit alone leads to complaints from the neighbours of my customers, and when it's accelerating from low speed, or breaking down a grade with the aux brake, you cannot hold a conversation even inside the cab (and it's a LOT noisier outside).

Nevertheless, phone zombies, and others with no obvious excuse, still hurl themselves lemming-like into my path. There's no amount of noise that will persuade these morons that it might be a poor life plan to step out in front of a heavy vehicle. Or better still, to walk behind one while it is reversing.

That's what Musk promised and it's not cool, because without doubt idiots would abuse it. Think of sounds of horses, lions, elephants and yes StarWars vehicles

In fairness, cars are already quite capable of making irritating loud noises.

Even though audition does not switch off at night, that we can be wakened by most any sound we normally aren't awaken by sound at night. It is very obvious we can set filters to keep noise of most sorts out of our conscious processes.

 Selective attention auditory

Recently, researchers have attempted to explain mechanisms implicated in selective auditory attention. In 2012, an assistant professor in residence of the Neurological Surgery and Physiology in the University of California San Francisco examined the selective cortical representation of attended speaker in multiple-talker speech perception. Edward Chang and his colleague, Nima Mesgarani undertook a study that recruited three patients affected by severe epilepsy, who were undergoing treatment surgery.^[7] All patients were recorded to have normal hearing. The procedure of this study required the surgeons to place a thin sheet of electrodes under the skull on the outer surface of the cortex. The activity of electrodes was recorded in the auditory cortex. The patients were given two speech samples to listen to and they were told to distinguish the words spoken by the speakers. The speech samples were simultaneously played and different speech phrases were spoken by different speakers. Chang and Mesgarani found an increase in neural responses in the auditory cortex when the patients heard words from the target speaker. Chang went on to explain that the method of this experiment was well-conducted as it was able to observe the neural patterns that tells when the patient's auditory attention shifted to the other speaker. This clearly shows the selectivity of auditory attention in humans.

The development of selective attention has also been examined. Jones and Moore for instance, studied how well children across various age groups could hear and respond to a target sound when it was masked by other auditory stimuli. They discovered that 9– to 11-year-old children became as adept as adults at paying attention only to the target sound and filtering out the masking sound (2015, p. 366). This shows that research on selective auditory information is important to continue as it allows us to better understand our world.^[8]

Training one to do things for which one had not developed adaptations is a tough row to hoe. especially if that system is the primary aert system for approaching danger. Human response to sound from any direction begins in as little as 10 ms whereas olfactory and other omnidirectional systems take at least 100 ms to begin assaulting cognitive processes. Vision of obvious restricted to the direction in which one has eyes open to see and it requires at least 50 ms to get awareness going evenif it is used for active looking for stuff.

Too much?

The main noises I get from cars nowadays are tire on pavement sounds. Cars are very quiet since their engine compartments and rolling equipment compartments are isolated both fromderinside* and outside by quietness and air flow engineering techniques.

You must not have many ... salt of the earth types? ... in in your neighborhood. Here there are plenty of folks who delight in making their pickup trucks as loud as possible, and playing country music or ranchero music at volumes that must be unsafe for their eardrums.

I live in a neighborhood where logging trucks play and huge tacters play. My first car was a dying '50 ford which had FU'd muffler system. C'mon we had an auto shop at school in the '50s where sound was everywhere. My kids grew up on heavy metal played in crowded reverberant places like the Whisky on sunset. Cruising had been a thing since I was in HS and I worked in Aerospace. You're going to tell me about noise. Ever try to work between two jet testing stations at a place Like Pt. Mugu? Finally, I got my advanced degrees in psychoacoustics.

Things are really quiet nowadays compared.

On the other hand I did my doctoral work in and Anechoic chamber where one could feel their eardrums press outward because of the silence.

I enjoy where I am now thank you. Love listening to winter storms make the house shake to 100 mph winds as they whip up the ocean less than a quarter mile away and thunder storms provide lightning strikes nearby because it's less than a second later that thunder rolls.

I really prefer quiet in the fall.

Another sound that should be added to cars:

When your antilock brakes engage they should make a sound like a locked-up tire skidding on the pavement would make. It used to be that the screech of the tire was a clear warning to pedestrians that they were in danger, now when you stand on the brakes there's no notable sound to warn them.

In NE Ohio, people like doing that to Hondas and the like. Yes, because a Civic with a really loud muffler is... cool?

The pickup people come in a few flavors, the most common is non-modders. But there are a minority of Monster Truck wannabees and the guys that like pretending they drive a choo choo and put a smoke stack on it.

If you are hearing screeching tires... and you are in danger... you will have just enough time to notice that you are in danger before being thudded.

now when you stand on the brakes there's no notable sound to warn them.

If you are standing on the brakes, you are driving in a really bad position.

When a pedestrian wanders out into the road where they don't belong you have to stop very hard.

I call dibs on Red Barchetta.

I call dibs on T-80

 

[fromderinside]

dibs?

 

[Gun Nut]

dibs?

It means that they are claiming ownership... "Calling dibs".

Often it's just about claiming usage.
