I was using a chisel to remove, by scraping, foam tape from aluminum
frames. I was listening to the radio through headphones while doing
this. An FM station if that matters. Anyway, sometimes I could hear
the tape separating from the aluminum. I thought the tape must be
making a lot of sound if I could hear it through the headphones.
Removing them only made the process silent. Putting them back on I
could hear the hiss again. I think that there must be a charge being
released when the glue is scraped away from the substrate.

Did it sound anything like the file at this link?

If it did, the aluminum was actually broadcasting
(The adhesive would have been acting as the electrolyte, your chisel
as the dissimilar metal)

There is a form of electricity called triboelectricity. It is related
to friction, but can indeed be induced when seperating adhesive
surfaces. Usually it is more intense with tape on a non-conductor. Try
removing a good tape from a surface in a completely dark room. You may
well see sparks and a plasma-like glow.
Yep - did a paper on the subject. Try good 'ole standard 3-M magic tape.
zaps nicely.
