LectroFan High Fidelity White Noise Machine

I tried another kind of comfort-sound generator, based on speakers making electronically reproduced noses and white noise. I did not like it at all. I tried this one, and I was sold. It really does the job of providing comforting, soothing noise to block out other ambient noise and help sleeping. Fans and air movement are the only way to go. It has two adjustments that let you tune it extensively to your liking, by changing the size and orientation of the holes that the air comes through because of the fan. The body rotates. This appears to mostly tune the frequency, with a smaller effect on the volume. The top also rotates, and appears to mostly tune the volume with a small effect on frequency. With a little fiddling you can get it just like you prefer. It masks trash trucks in the street outside and wailing Burmese cats outside the bedroom door. Won't ever be without one of these again.
