Can You Hear that Sound, or Is It Just Me?

Kary Anne Tamblyn of Ellicott City, Maryland, writes:

Marilyn: A reader wrote that he hears "a certain pitch in [his] head" even when he thinks there's no sound in his bedroom. (January 4, 2012). You stated that he may have tinnitus, which might have been caused by his running of large machinery for many years. But that certain pitch may also be the hum of alternating current (AC) in power lines, power transformers (including AC adaptors), plug-in digital clocks, and devices that use electricity even when they're powered off (such as televisions with remote controls).

My parents have lived in Ellicott City, Maryland, since 1959. Back then the population was about 3,000, but today it has exploded to about 65,000. With this increase has come a great many more outdoor power lines and transformers. In my parents' own house, the number of AC adaptors, plug-in digital clocks, and devices with remote controls has risen from zero in 1959 to more than a dozen today. My parents say that they have noticed an increase in AC hum over the years. I've noticed it, as well.

Marilyn responds:


Yes, the world is a noisier place these days, all right!
