Air Cod. Avionics sound file

Hi all,Does anyone know were I can get hold of a sound file for the humming of the air conditioning and avionics that can be heard on the flight deck? SSW is developing an A310 but do not have the sound file for this part of the product, if they couldn't include it this would be a huge shame as sound is such a major factor when it comes to 'feeling like your there!'If you have one couldyou email me it at [email protected] contact SSW at www.simsoftworkshop.comThat would be great! Thanks
