The new V6 Turbo engine sounds

[CHT]

As far as I can tell the hype around the new technology far exceeds the potential PR downside about the sound. Anyway, competitiveness and public interest in driver personalities is a much bigger driver of tickets sales and TV audiences than dB.

What hype? What personalities? You are wrong, the lack of sound will keep people away. I'm afraid the drivers have no personalities anymore, they are nothing more than media savvy corporate robots. Also I failed to see much competitiveness on Sunday. I hope they sort this out, F1 needs noise, it's the signature of the sport.

You missed Bottas carving his way forward twice? Ricciardo keeping his RB10 in second?

It's amazing to me what change does to perception. F1 is the same as it's ever been.

How many merc powered car did bottas over took during the weekend? With the current kers boost system no one know for sure why overtaking is now so much easier than before. Does anyone still care about drs zone?

DRS has so far been trivial in Melbourne since DRS became a thing. I was glad it was barely mentioned, honestly. Same with tyre management.

On the TV they mentioned that the sound of the engines use to be 150db now they are below 100db, the legal limit for a road car is 98db!!! Try going to a concert and getting them to turn the volume down it just wouldn't be the same. From a spectators view the sound is very important and something should be done about it.

The new power plants are great and the cars look challenging to drive, which will make for good racing, but we need to feel and hear these cars to create excitement.

That's not quite true either.
The V10s did over 150db on the test bank, and about 141db in the car on track.
The V8s did 144db on the test bank, and about 134db in the car on track.
The V6s do 134db on the test bank, so I reckon about 125db in the car on track.

For those who don't know, be aware the decibel scale is logarithmic, so a reduction of every 10db is half the volume.

what do you mean? that although it looks 9db quieter its actually a lot more, half the loudness of the v8's?

[Stevier]

Yes 9db is almost half the volume.

I mean the scale is not linear, due to the extreme variance from the quietest sound to the threshold of hearing.

Some mentioned the legal limit for a road car is 98db. Twice that volume is 108db. Twice the volume of that is 118db, and twice the volume of that is 128db.

If you are not used to the scale it appears like there is not much difference in sound for a small amount of difference but there is.

Anyway the v6s need to be more angrier sounding and louder full stop. Personally would like the 3L v10s back.

[astracrazy]

ok i get you, so the new v6's are just under half the volume - so there actually much quieter than people think. So when the fia are saying they are not that much quieter, look its only 9db down. Actually what they mean is your right, there nearly half the volume.

Decibels vs percieved loudness.

The general consensus is also that the minimum difference for a human ear to notice a change in volume is 3db.

PS I am new to this forum, I joined at my disgust of the new formula 1. Look forward to getting involved in discussions.

welcome, thanks for the information - taught me something new

10 db is not 2 times! it is 10 times.

3 dB more power means twice more power.
10 dB more power means ten times more power
20 dB means 100 times more power.
etc...

[astracrazy]

its not 10 times its half, have a looked at the link provided?

Loudness (sones) vs Sound Intensity (db)
1 sones = 40db
2 sones = 50db
4 sones = 60db
8 sones = 70db
16 sones = 80db

v6 engine is say 120db so 100 sones, the v8's were 130db so 200 sones (roughly/rounded down) - so half as loud (-10db)

You guys ain't heard nothin' yet. Engines will only get quieter over the next few years as they're developed more and more toward better efficiency.

Sounds good, right?

[astracrazy]

i don't think so, there will be a point where the fans won't take it. f1 is bordering on that line now. This is all to please car manufactures but whats the point if there are hardly any fans to watch the sport? they wouldn't have any interest in the sport then either.

[bhall]

Works for me.

"A little rebellion now and then is a good thing."

[Stevier]

I can't remember exactly the db thing. Loudness and volume are not quantities that can be measured and are terms we use to describe the way human hearing works.

A gain of +10db equals a perceived volume increase of a factor of 2, but the sound intensity is different, can't remember exactly what.

This is a good link explains it,

10 db is not 2 times! it is 10 times.

3 dB more power means twice more power.
10 dB more power means ten times more power
20 dB means 100 times more power.
etc...

Yes that is correct and incorrect. 3db is twice the power, but not twice the perceived volume increase.

Power does not relate directly to the way human hearing works.

A 100w guitar amp is twice the power of a 50w amp but only 3db louder, only barely noticeable.
