I've been through some initial sound analysis of the available engine sounds, unfortunately the videos are having quite unusable audio quality. On that note, I will be doing full-blown professional sound analysis of the new engines once clear sounds are available.
I must say, however, that the more I listen to them, the more they grow on me. Inevitably, when there's a change, there's a resistance due to habits, but these engines sound both mechanical and complex at the same time.
What is real relief is the sound when it's attached to chassis and exhausts with full track acoustics. Long time ago certain previews were available and they sounded, well.. strange, at best.
What's your take on 2014 engine sounds?
Update: I just ran a new poll about it - http://www.f1technical.net/poll/index.php?dispid=266
