I am interested in purchasing a white noise generator for masking road noise in a bedroom .
I looked at a few on amazon and cant decide if the "fan in a box" mechanical type or a digital model would be more effective at blocking the low frequencies from trucks passing by .
Anyone ever use these and had good/ bad results ?
