Most people don't realise that a lot of the sounds in films and so on are actually added in post production, and there are all sorts of tricks to get certain effects.
No no, I realise only too well - if there is one thing I hate about them, its when there is something on the telly that you know should sound like, but the noise on the telly bears precisely feck all resemblance to it.
One fantastic example are trains actually, I mean, any kind of diesel or electric passing by at speed very often gets that whineing, whish noise that HSTs (Intercity 125s) used to make (they don't even make the noise any more!). The reality is that the train often sounds nothing like that, but no, everything instantly has to be an HST because it sounds dramatic!!
It might not sound like much, but its one of these things that once you notice it, you hear it all the time! In fact, you, hear them all the time for other things, planes, boats, buses....... I could go on.
The irony is that, instead of it being lazy, it actually takes effort to add a new sound in when there is one there already, I mean FFS!!
