10791Re: HUM_FORUM: Analysis of Hum Simulation Audio Files
- Dec 2, 2008Is there any useful data in the Hum simulation files? I think there is (though I admit, I should have stopped at the assignment of pitch--the rest of the information with sound wave files is rather irrelevant to anyone but the creators, so I have deleted that information). I wanted to perform a thorough analysis of the simulation files to show the similarities and differences between the files, especially with respect to pitch. With the large amount of variability, one might ask if we are all hearing the same thing; it appears that we are not. The assumption is that the creators successfully simulated a sound that is true to their personal experience with the Hum.
The question may be raised, why would anyone want to try to recreate what they hear. For me, I wanted validation that others hear what I do. Perhaps another reason would be to allow non-hearers a chance to hear what Hearers hear (though I have not wanted to draw any attention to the Hum with my friends who are hosting me for the winter). From this point, two questions may be asked: 1) If two or more people listen to the Hum in the same room and their perceptions differ in pitch, one might conclude that something about their personal hearing processes is different (anatomical, physiological, etc), or 2) If people are accurately simulating what they hear, the fact that so many of the sounds differ in pitch may indicate that there are different sources of the Hum.
I am not trying to find out anything about a possible source of the Hum by studying the simulation files and for me, the audio files that I have listened to that claim to have captured a recording of the Hum do not sound like that Hum that I perceive. From my own attempts at recording the Hum and reading the reports from the archives of professionals that have attempted and failed to record it, I do not believe that it is possible to record it--I have serious doubts that it is an acoustical phenomenon.
