Vibrations and such

[Petrus]

Found an interesting piece of info from Toyota:

Stop whinging and educate yoself boi

Boi boi

Take it Helen is out.
Language like that.
Tut tut.

She won't be happy.

[shnazzle]

Haha. Helen is where she always is... No more than 5ft from me

[Ardent]

Say hello for me.

I will take the slap down for being OT.
But, is there a spell check option available that can be switched on?
(Or there is but I've never found it)

Back on topic.
Although not specifically 2 related.
Would that link be suitable for the ref section.

The page counter,or whatever computing gizmo indicates page numbers, shows 1/44 etc. whereas the actual pages are numbered 3 - 46. I wonder if that has led to any "interesting" conversations?

[Joesson]

One of  our number recently made an indirect reference to this, concerning a Mechanics method of "testing" wheel bearing condition by touching the relevant coil spring and rotating the jacked up wheel.

I wondered if Boi was from the OP's "native" language, however with reference to Wiki it is simply slang for "boy".

However a specific Boi,
Dat Boi is an Internet meme originating from an "Animation Factory" animation of a green unicycling poison dart frog. ... It is usually accompanied by a person saying "here come dat boi" to which he replies "o shit waddup!"
Dat Boi - Wikipedia

This reinforces my belief that everything affects everything else. What else could explain how a technical paper about Vibration links to a green frog?

I believe I have seen that paper before or something like it which is a good read.

Here is my take on it. Abnormal vibration, harshness and sound is a good way to diagnose component wear and defects.

Having said that it is pointless to eliminate most of the sound or vibrations  because what ever sound you eliminate you will then  amplify what was unmasked. Some frequencies cancel out each other so it is more important to have the right kind sound as well as the right vibrations. 
    Its kind of like hifi audio when it comes to amps. If you try to clean up a signal too much or power supply you might actually make it sound lifeless, however if you add 2nd order distortions from a tube amp you can make it sound nice. 

This sort of science is still poorly understood but now manufactures are purposely tuning engines intake tracks to sound better based on research which has very little to do with performance.

Like Yamaha development of Lexus LFA intake manifold 🙂 (goosebumps) https://youtu.be/BWrmXO4GjSY

like that.

Top tip. Works very well with headphones.

Thats when I first heard of the technology but then I found it was closer to home because the 2ZZ white papers allude to the intake manifold was design for a sporty sound. 

I also found out that the Lexus V8 cars have a aftermarket intake resonator developed by Toyota to improve induction sound. This was made for a luxury car which is just silly.   
 
I remember in the past when Infinity (Nissan) had an advertising campaign on materials used in the manufacturing that smell like wood and leather rather than plastic.

Who knows maybe they will put in rumble packs like game controllers  to simulate vibration in the steering wheel. Oddly enough my Brother in laws Cadillac Escalade has that feature if you veer off the road and it will also vibrate the side of your seat .

In more than a few ´sporting´ luxury cars from Audi, Porscha´h, Bmw to name but a few, the interior sound is actually a sound track on the audio system with several modes/tunes to choose from.....
