I be really bum that this one do not work out . I be look for a white noise machine and I only use the `` rain '' and `` white noise '' sound and they loop be WAY too short . I be a bit neurotic and obsessive about little thing and be sensitive to pattern . the `` rain '' setting be about a 10 second loop and I could pick out a faint ` tap tap tap ' and I , of course , focus on that , every 10 seconds . then I go to the `` white noise '' set which have a even fainter problem noise , on a even shorter loop , about 5 seconds . I also feel that even the lowest noise setting be not quite low enough -lrb- I have the clock close to by head -rrb- . and the light emit by the clock be really bright , even when turn on low . maybe this will be better in my son 's room ...
