RE: Nice NVH srory

So who are the drivers?
Airbus, and Boeing ?

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them.  Old professor

I noticed that too Greg. I think in BBC-language, technician > engineer.

RE: Nice NVH srory

This is not the BBC but England as a whole, Engineers aren't respected and panel beaters, mechanics and roadsweepers call themselves engineers. If a qualified engineers complains he's mobbed against and called a snob. The General perception of an engneer is about the same and this is reflected in the typical salaries there too. That's why I got out!

I resemble that remark, I was a member of the National Union of Sheet Metal Workers, Coppersmiths, Heating & Domestic, Engineers.
But I never called myself an engineer.

IR is technically correct in that the article doesn't call him an engineer. Although it does use the term to describe the unskilled labour that's assembling the engines.

In our company, if an engineer doesn't want to be promoted to a manger, he/she can opt to be promoted to a technical specialist instead with the same grade and perks.

RE: Nice NVH srory

Thanks for that link - what a wonderfully mad creation that is.  The noise......!

RE: Nice NVH srory

Interesting but I have my doubts.  I've had a couple old sport cars and been around a few more.  Three of the most awesome sounding exhaust notes that I have personal experience with were a 1938 Alfa, a 1949 Jag (and a later E type) and, a 60 Maser duoporte  that I drove one Sunday morning down Colorado Blvd. in Pasadena in the late 60's.  I'm reasonably sure that there was little if any input from an "audio engineer" in the sound of those beautiful cars.

Hey, my old '50 TD didn't sound too bad, either.

RE: Nice NVH srory

I'm pretty sure (I heard it many years ago and I could be very wrong) that the exhaust note was so important to the Bullit car chase experience that it was said that they dubbed over the sound from cars other than those used in the chase..... still one of the best movie car chases for me. Plus I prefer the exhaust note from these cars than that prima dona screech of formula 1 cars. Especially the sort of gurgling bubbly note when ticking over.

Still, all this work will doubtless be valuable when they have to create exhaust sounds for electric cars.

RE: Nice NVH srory

I still like the sound of a Japanese sports bike, especially as the induction roar starts to drown out the exhaust note. I have occasionally had cars with a similar sound, well at least similar to the bike at WOT, but still only half way through its rev range. I guess I am saying I like the induction roar of IR manifolds with big dia ITBs and no plenum more than I like exhaust noise.

RE: Nice NVH srory

I agree, Pat, with one notable exception. (One Upsmanship...name of the game) ;o)    
Best bike sound was a six cylinder Benelli. Closest thing to a V12 Ferrari on a bike.

Best induction...standing on the pit wall and listening to my son in the Lotus Cortina twincam/45 DCOE Webers/8500rpm coming at me.

Best exhaust sound overall...Damon Hill's Williams Renault V10 back in the mid 90's.  Awesome but LOUD.  Even with ear plugs and my hands clapped over my ears...Most of the Renault's seem extra loud.

I suppose it's "different strokes for different folks"...these are mine.

RE: Nice NVH srory

I did a computer simulation of my old RD350 (2 stroke) bike engine a few years back. It included the intake and both exhausts, radiating to microphones placed at left and right ear locations. Awesome! The stereo effects of the exhausts was picked up perfectly. I may post the sound file if I can find it.

I had a friend with the same bike once. On biking trips we could get our exhausts to beat when riding close to each other, in the same gear.

JMW is describing burble, a characteristic of cross plane V8 engines. You'd never hear that from a flat plane V8.

Blinking flip. New keyboard required too.

RE: Nice NVH srory

I had an RD400 ('77) and an RD350L/C ('81).  Both great bikes but I never thought the exhaust sound was anything special.  Now my Triumph Speed Triple 1050 at 10,000 RPM makes a beautiful wail.

... bought my first proper bike (GPz550 H2) based on the noise. I4, 4 into 1 exhaust. Smitten at first fire. Crap handling though.
