Default Engine noise during ilde

I haven noticed this faint random knocks coming from the both sides of the engine during idle. It seems to be more apparent after I drove the car only a few miles. The frequency of the knocks is random - it would knoks 3x, wait a couple of seconds, knocks 2x etc...

I took it to the freeway for a 10 miles drive and pop the hood, I couldn't hear it....

Any idea whether it is normal? Thanks...

car has 40k miles and oil change every 3-4k miles.
