| 168714 | 2003-08-19 12:12:00 | BeSweet is a audio convertor. in this tool its asking me to set the output speaker configuration but iam not sure if the sound level -5db is big or 5 db is big |

If a level of -5 db is increased to -2 db, the power output is doubled as an example. Increasing again by another 3 db gives +1 db So (+) 5 db is a lot louder than -5 db. (if my mathematics have been remembered correctly) |

| 168717 | 2003-08-20 06:32:00 | When comparing voltages, an increase of 3dB is a doubling of voltage, too. :D However, a doubling of voltage (in the same impedance) will quadruple the power. Confused yet? dB are logarithmic. When you add logarithms, you are multiplying; when you subtract them, you are dividing. So plus --> bigger, Minus --> less. |
