I think you are refering to a deer's "blow". This is not an attempt to attract deer nor should it be used by hunters. This is a distress call to warn other deer in the area there is potential danger. The blowing is short sounds that are somewhat loud and high pitched.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
