decibels A-weighted

check this out:

"The dBA measurement is made with a sound level meter with an A contour filter which provides the best instrument match of the ear's equal loudness curves for soft sounds in the neighborhood of 40 dB. When this filter, (which is one of the standard contour filters of most sound level meters) is used, the levels should be recorded as dBA rather than dB. The unit dB implies that all frequencies in the audible frequency range are treated equally - something very different from what the ear does. A good practice in sound level surveys is to measure all levels in both dBA and in the flat-response mode where the intensity in decibels (dB) is measured directly. Measurements made in dBA approximate the loudness level in phons and are practical to make with a standard meter. "

As werk pointed out, in all non caps it stands for "doing business as", as in The Marriage of Mammaries and Alcohol Corporation dba Hooters.

Perhaps a better example . . . you open a pizza shop. You call it "Joe's Pizza". You have to incorporate yourself legally. Your corporation is The Anchovie Corporation. You are now The Anchovie Corporation dba Joe's Pizza.
