3DB at AllExperts (650 words)
3DB was a commercial radio station in Melbourne, Australia and for many years was considered one of the "old guard" of Melbourne radio.
In the pre-television Golden Era of radio 3DB consistently rated number one but the arrival of television and the consequent conversion from Old time radio to music radio were to bring a succession of troubles for DB.
In 1987 the HWT 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 in 1990 - as of 2005 the station uses the moniker Mix 101.1.
Optimize Your Volume (1319 words)
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.
