Will the new 2014 engines be loud enough?

[Smurfer]

I understand that "loud enough" is subjective, what I'm really getting at is whether the level of decibels will be similar to that of the current V8 engines.

Personally, the level of noise and sound of the current engines create emotions that I associate with F1. I've been to 4 races to date, 2 with the old V10 engines and 2 with the V8's. Being at Melbourne last weekend and hearing the cars exit the pits from the other side of the circuit is something to be savoured. It's amazing that they can make the Aust V8 Supercars sound quiet and civilised.

No doubt the pitch of the engines will change from 2014 though wondering if the level of sound will drop significantly. I would think so given turbo engines are generally more quiet than their N/A counterparts. That said, I'm certainly no expert so would like to hear from people who know more about the topice.
