A DIY acronym Data-base/'Sticky' thread?

[Richard Ellis]

An idea perhaps for a "sticky" thread.................How about an acronym data-base, file base for the DIY community. I ran across an acronym just now.....can't seem to nail it down....A BIB?? Each acronym could be broken down according to its point of interest....'Full-rangers, Tubes, Solid-state" each according to its application. This would make things a lot easier, helpful and we would all learn more.

Sounds like a good idea to me. Your BIB made me think of ‘PRaT’ I would see it from time to time here at diyAudio but was clueless. Found it at TNT-audio after a google search –

PRaT:

1. Pace, Rhythm and Timing
2. could have been: Pitch, Rhythm and Timing
3. could also have been: Pace, Rhythm and Tune
4. but never Pitch Rhythm and Tune, to my knowledge

PRaT pace pitch rhythm timing tunes PRaT - [English]

Start one, we can make it sticky. If we don't watch out this is it

DIY = Do It Yourself
BIB = Bigger Is Better. Tapped Conical Pipe/Horn, Usually associated with FR
FR = Full Range. 1-way speaker systems
FR = Frequency Response
ML-TL = Mass Loaded Transmission Line

low bass: 20-40Hz
midbass: 40-80Hz
upper bass: 80-160 Hz
lower mid: 160-320Hz
mids: 320-1280 Hz (2 octaves)
upper mids: 1250-2.5k
lower treble: 2.5k-5k
mid treble: 5000-10k
upper treble:10-20k

wow Dave those figures for bass are very different to what I had in my head! I often see 5" or 6" drivers reffered to as MidBass units. I'd always thought midbass was in the 100-800 Hz range, and mids in the 800- 2000 range.... Live and learn!

Human voice fundementals are something like 80-800.

IC=integrated circuit, IC=interconnect cable

[ostripper]

I find myself explaining these ones , over and over...

OPS - output stage
IPS - input stage
OP - output
VAS/VS - voltage stage or voltage amplification stage

CM - current mirror
CSS - constant current source

TMC - transitional miller compensation
CMC - conventional miller compensation
TPC - two-pole compensation

EF (2/3) emitter follower (2-stage or triple)
PS - power supply

I'm sure there are others. (GEB = golden ear brigade )

OS

Some of those you have to keep explaining because they are not widely used. For example, OPS and IPS - I have never seen those used. We need to be careful not to invent new ones all the time. There may be cultural differences here: some people like acronyms (to save typing) so use lots including non-standard or newly invented ones, others prefer clarity so use just a few well-known ones and spell out everything else in full.

One thing even someone who is fairly ignorant like me has to frequently explain to friends, particulary as they pertain to (cheap) surge protectors is:

MOV - metal oxide varistor

Why not make a wiki page?
