What is the noise level of the Panasonic PT-AE4000?

It is quiet. Projector Central said it was around 22db and I believe it. I sit 3 ft below mine and the PS3 acros the room made more noise

Ditto...cable box is louder. I hardly notice it.

has anyone noticed the fan kind of pulsing, i.e. not a smooth consistent noise. This projector is my fourth pana (ae3000 ax200 ae900) and seems the loudest.

have sent back to panasonic who replaced the fan and said the set up internally is different and pushes over the power supply, any way still pulsing on eco mode. replies would be appreciated as i want to be happier about my purchase. I too sit close about 4.5 ft apart from the noise it is beautiful.
