Before I say anything else, I agree with what's being said here.audtatious wrote:A Sport Sedan is supposed to be luxury quiet? Since when?

Thank you, someone put it better than I could. 3db may be doubling the noise, but go turn on your surround sound. When you adjust the volume, it does so in decibels. When you turn it up 3db, it isn't twice as loud as it was before to our ears. Use it as an experiment with someone else using your remote to see how many dbs it takes you to notice they're turning it up or down, you'll start to notice it at 2db when quickly changed. They are equal steps of intensity because dbs are measured on a log scale.Kendahl wrote:A 3 db difference in noise level means a factor of two in power. Human beings sense sound and light on a logarithmic scale. 73 db means twice as much power as 70 db, 76 db means four times as much, and 79 db means eight times as much. But, to our ears, they are equal steps of intensity. I have read that 2 db is the smallest difference a person can detect. Therefore, you should be able to notice 3 db, but not 1 db.
Please don't do that... Joe and I will have our hands full... besides... that's something they would prolly do.infinitgkid wrote:i should go on a bmw forum and post a link to this topic...

I have a passion for all cars, BMW, Ferrari, Porsche etc. I'm hear to learn about my new car and every time I check the forum it's the same thing.

To dumb it down, it requires 1db SPL (Sound pressure level) to make any difference noticable to the human ear (In this case it is "I think I notice a difference"). 3db is generally noticable and 6db is easily noticable. 10db (or 10x) is perceived as twice as loud. Thus, a car with 50db at idle will be perceived as "twice as loud" inside when compared to a car with 40db.Kendahl wrote:A 3 db difference in noise level means a factor of two in power.

If you read many road tests, you will see that the noise level at 70 mph is in the upper 60s for quiet cars and upper 70s to 80s for noisy ones.
