I know a great deal about frequencies. F'rinstance, my frequency between 11:00 PM and 6:00AM is about 5 times. Nah...not really. :>)

Hotrod, me bucko, I'm a bass player. Do you not think I know where the frequency of that instrument's range lies? That's why they don't call it a piccolo or sump'in else. Capish?

It's not the frequency of the noise (note I didn't say music) that eminates from those abominations, it's's the excessive DBs...I repeat...the dreaded DB's which injure the ear. Generally it's the high frequency response that will suffer first and then, if you don't give up those silly toys before you're 30, you'll force your grandchildren to learn ASL ( look it up) to communicate with you. :>)

A little trivia question about a frequency. What is 440 CPS? Anyone?
