 Optimize Your Volume
3dB is just enough difference that you can barely tell the volume has changed.
With that in mind we can move on to what is required in terms of power (measured in watts) for an amp to create a 3dB change.
What this means is a one watt signal is played through the speaker and then its SPL is measured at a distance from the speaker of one meter.

And it is important to note, that during the course of a ChannelBUILDER project, most of the sales partner prospects we identify and recruit will come from sources other than our internal database.
Your ChannelGUIDE will be developed by one of the senior managers of 3dB Global (each specializes in a different set of markets).
Before your ChannelGUIDE is created, the senior manager will have a telephone meeting with you to review the geographic territories you have selected and to discuss any other requirements which may be relevant to the partner selection process.

 3DB - Wikipedia, the free encyclopedia
The original studios were located in Capital House, Swanston Street, Melbourne.
Note the modern Herald Sun was two separate papers at the time.
In 1987 the HWT group sold 3DB to the Albert Family who changed the call letters to 3TT in April 1988 and the station ultimately converted to FM and became 101.1 TT-FM (legal callsign 3TTT) in 1990 - as of 2005 the station uses the moniker Mix 101.1.

 openCortex: ARTICLE: The 3DB and solar cars
Typically dry weave Kevlar K-120 plain at 1.8oz/yd2 and 5 mil thick or K-285 proflux satin at 5oz/yd2 and 10 mil (used in 3DB) are used for the shell.
I have learned that the shell of the 3Db was made with prepreg cured at 250˚ C or 200˚ C with a vacuum bag.
If you look at the shell and “cockpit” on the 3Db you will notice that between layers of carbon fiber or Kevlar is a layer of little honeycomb-like structures.

 +3db whenever I bounce a track?
After some years using sonar I just realized whenever I bounce a track the new track is 3db louder than the former.
The only plug-in I inserted in the original track was sonitus gate, so I disabled (no plug-ins now), set the fader to 0db and I try to make the bouncing again.
I compared the two tracks and the bouncing is 3db louder.

 What are -3dB limits? - Club Polk
Actually if the speaker are rated as 40-26k +/- 3db, that means that there is no noticable difference in volume between any frequencies in that range.
The overally response is going to by much more faded, and the 28 hz "overall" may actually be -10 or 12 db or significantly less.
A 3db increase in sound is DOUBLING the volume...and a 3db decrease would cut said volume in half.....

3dB English ceilidh band, was formed out of the Seven Stars Ceilidh Band specifically to perform for dance functions in a noticibly English style.
Through FSW I became more appreciative of the folk music of the region, and so started 3dB a ceilidh band specialising in English music and dance, with the novel twist of incorporating a sprinkling of Ukrainian music alongside some previously unpublished Devon tunes.
Simon started his professional career in the 70s playing in folk clubs in England and Scotland, before moving to the Shetland Isles where he became involved in local bands and traditional music.

In that case would it be a good idea to attenuate by 3dB at 600Hz?
I don't know if in reality it ever does achieve the +3dB bost, since the mids and woofers and physically quite a ways apart (relatively speaking that is).
Well, the crossover frequency is usually defined to be the 3dB down point.

 DBL: Files: On the 3dB rule
What I found interesting was watching the mixdown process using Cakewalk and observing how a 1dB change would noticeably change how a track sat in the mix.
So that got me to thinking about the conventional wisdom that a 3dB change is "just barely noticeable".
Perhaps that's based upon hearing the change in isolation...

 +/- 3dB??? - Club Polk
I know I've been here for awhile, and I really should know this, but it's just one of those things you think you know but never really were sure about.
For example, the Hsu VTF-3 says its lower limit is 20 Hz +/- 3dB in max.
I know, I know, SVS is the best at lower frequencies, but I'm not sure my new place, or budget, will be big enough for an SVS at this point.

 Is it true that every 3db doubles your signal? - towertalk Forum at eHam.net
Doubling power is not the same thing as doubling the distance your singal will be heard.
If you double your power, that is an increase of ONLY 3db.
If, say, you had a yagi with a measured gain of +12 db, a coax line with -3 db loss, you "add" these to get a total system gain/loss of 9db.

 Cone area myths - double cone area - 3db - 6db - correllated sounds - double woofers - physics - eddie runner
It may not, because there are so many variables between the point of the energy being electrons and the energy making it to our ears.
There are several variables that may not always have the same value and thus it is impossible to guarantee that a 3dB increase will occur.
Along this path from electrons to sound, there is also a lot of our energy that is turned to heat and the heat does not translate to more sound, so there is some loss, quite a bit as a matter of fact..

 NetNimble 2.4ghz ISM Wireless Internet Antennas, Routers, CPE   (Site not responding. Last check: 2007-10-13)
The signal margins represents a 3db reduction from the maximum focus.
Thus, a 120-degree sector antenna can actually cover a 180-degree area with more than a 3db reduction in strength at the 30 degree margin areas.
For our 12dBi 120-degree sector antenna there would be a 4dB reduction for full 180-degree coverage, which would be equivalent to a 8dB antenna in those areas.
