Dual carb guys

Hey, Just wondering with all you guys that have dual carbs with individual air filters, Do you notice a pulsing rumbling sound through the intake that increases as the under bonnet temperatures rise? I realise that there is always going to be a throaty roar, but this seems to get deeper as it gets hotter.
