Useless audio trivia thread

[Sigma]

reading a 1966 Popular Science last night i discovered the c.p.s. was the standard term for audio frequencies until..you guessed it 1966 when Hertz was adopted..

seems that c.p.s. stood for differnt things in dif languages so scientists wanted a unique universal term.


namd in honor of Heinrich Hertz ..the abr. hz became the new universal term for audio frequencies

i didn't know it was that late in time!

Cycles Per Second - what else did it stant for? I've also come across HZ refered to as, simply, "cycles" ("kilocycles" ets) by old literature or old techs.

Candle Power Seconds for one..

CANDELA SECONDS or CANDLE POWER SECONDS – This quantity is the actual light energy contained in a pulse of light. Candela seconds is used by the Society of Automotive Engineers and the California Highway Patrol to specify the minimum requirements for light output from a flashing light because flash energy has been shown to be a relatively accurate and fair way of comparing radically different types of lights such as incandescent rotators and xenon strobe lights. Candela seconds is merely a relative measure of how bright a flash of light will appear to a human eye. A light with a higher candela second rating will appear brighter than a light with a lower candela second rating even if the lower rated light has a much higher peak candela rating.

plus they wanted a term that would make sense in any language

july 1966 Popular Science

kilo- is a metric prefix.


so why is their no metric music scale ?

The hertz is named after the German physicist Heinrich Hertz, who made important scientific contributions to electromagnetism. The name was established by the International Electrotechnical Commission (IEC) in 1930.[2] It was adopted by the General Conference on Weights and Measures (CGPM) (Conférence générale des poids et mesures) in 1960, replacing the previous name for the unit, cycles per second (cps), along with its related multiples, primarily kilocycles per second (kc/s) and megacycles per second (Mc/s). The term cycles per second was largely replaced by hertz by the 1970s.
The term "gigahertz", most commonly used in computer processor speed and radio frequency (RF) applications, can be pronounced either /ˈgigaˌhɝts/, with a hard /g/ sound or /ˈʒɪgaˌhɝts/ or /ˈdʒɪgaˌhɝts/, with a soft /ʒ/ sound at the beginning of the word. The prefix "giga-" is derived directly from the Greek "γιγας" and hence the preferred pronunciation is /ˈgɪga/. Some electrical engineers use /ˈdʒɪga/, by analogy with "gigantic".

hey i'm just quoting popular sicence magazine..they said enuff international organizations agreed that they were switching over too

Here's one that some may not know:

The Decibel is an updated unit of the Bel, which was invented by Bell labs and named after Alexander Graham Bell.

10 decibels = 1 bel.

Or, if you prefer, 0.1 bel = 10 decibels.



Apparently the guys quickly figured out 1 bel was WAY to big of a unit to be useful...

yup that's why it's notated dB [with a capitol B]

I like to write NFG on flaky gear. With a sharpee. Sometimes I use board tape so as not to cause unnecessary work. Sometimes I write directly on the gear.

You did say useless information. So far, everything above seems useful.

i stick with
"AFU"
or
"FTT" = fu** this thing

You see. That just might be the greatest service one audio guy can provide for the next audio guy. How many times have we been burned by some idiot throwing the same shit gear or cable back into the mix. I for one would NEVER do that to anyone. Bad karma.

As for cables, I've grown fond of just hacking off the connectors. Saves time.

[tINY]

I "Widlerize" bad components (smash them into little bits). Bad connectors get cut off like slipstream does.

Bad units get taken out of racks imedeately.

i didn't know it was that late in time!

wasn't he later honored with a car rental company ?

i've always wondered if they were going after the "wheels per second" if one considers that cycles = wheels in certain definitions.

i've also said that it hertz to rent a car.

i'm here all week folks, tip your waitress...
