Reverberating sound, which is auditory and intensely loud.

I am alone and sitting on our three-season porch with the window open, while finishing a class assignment for my online University, when a unnatural sound begins to occur. The sound occurs out-of-doors, and I am able to hear it through my screen in the window. The sound is somewhat loud and reverberating. After 9/11 I did hear government planes flying over our house, this sound I am hearing at this predawn time is reverberating, and is definitely NOT like that noise.

I live in a suburban/urban city area, which does have traffic noise, sirens, children playing, and other constant natural sounds (birds, dogs, etc.), which I am used to, constant airplane and helicopter traffic, and occasional gunshots. Some of these sounds did occur at the same time I am hearing the reverberating sound, but not all of them. This new sound, which is auditory and not internal, is a constant sound, which does last for a duration of fifteen minutes or more.

During the reverberating sound, I begin hearing an unnatural pitch, which is not a part of the reverberating sound. The pitch goes high and low like a tuning fork sound. This occurs as the reverberating sound continues and the tuning fork sound is one to two seconds long.

The emotional response, which it evokes is ominous. Psychologically, I do try to rationalize and recognize the sound. I begin thinking as to what the sounds may be and what I usually am able to hear. I then try to decipher if the reverberating sound is one I have heard before. I do try to come to terms with sound, as something that may have been natural, but I was unable to do so. The reverberating sound and the tuning fork like sound, do not in any way sound like a natural occurrence, which is auditory. I am unable to capture the sound with my computer web camera app.

I leave the area after the tuning fork sound, as I am frightened and unable to investigate it further.
