As I am using it, the noise increases in intensity like it is a jet plane about to take off...Should I take cover?! I have tried turning it off and restarting it, which stops the noise for a short period, then it starts up again...it is about 18mths old..

could it be your fan is running fast because your Macbook is getting hot?
try doing a SMC RESET and see if the noise goes away.
Hi, thanks for responding so quickly. I haven't been using the laptop any more than I normally do...it used to get very hot after using it for an hour or so...actually I didn't notice that it was hot last night when the problem started...do you think that it might be a fan? The noise is so loud, it sounds like someone is mowing the lawn!
if the bottom is getting warm - it might be the fan running to keep your processor from overheating.
open activity monitor - and under all processes not my processes - see what's using 10% and above in your %CPU section - anything running 15% and higher will cause your fan to spin faster.
watching videos or youtube videos will also make your fan spin faster and louder.
see image below of my activity monitor - see All Processes - see %CPU section and notice a little arrow pointing down in the %CPU section.
This is too long after the OP's post. anyway, hopefully this might help whoever looks for an answer in future.
I had this strange whirring noise too in my MBP, like really loud. I reinstalled the OSX just last night, and it went away.
Now I am crossing my fingers it stays away. Hopefully it'll work for someone else looking for a solution too!
Thanks. This really helped.
My MacBook Pro is making a loud whirring noise.
