In Masaschusetts, license plates from 2005 are of the form xxxx yy. My license plate 1951 HZ is purely random. Recently, someone with a musical bent asked me:
"You're a thoughtful person. I'm sure your personalized license plate has some profound meaning. What subtle and amazing thing happens at a frequency of 1951 Hertz (HZ)?"
Ok, I need some help here. I've done my best to search the web for phenomenon that occur between 1900 and 2000 Hertz. Here's what I've found so far:
*It's a common form of audio tone remote control from the 1970s.
*It's a common frequency of frog mating calls.
*It's the frequency of the humpback whale grunt.
*It's the frequency of alveolar nasal consonants (such as when you say "mmmmm").
*It's a point in the audio spectrum used to analyze noise induced hearing loss.
Ok, so far, my profound license plate has me
1. walking into a swamp and asking some wayward frog to hop down to my place
2. getting the attention of a distracted humpback whale
3. having my nasal consonants misunderstood by folks who frequent rock concerts.
I welcome your help - my car needs a sublime story as to why 1951 HZ says something about me, the human condition, or the natural world. Comments welcome!
