- You stepped up to be the best networker you could be at this event by being curious, committed, caring and challenged. Notice how you don't stand there, anymore, on a mission to hand out the pile of business cards you use to have in your hands. Instead, people are asking you for your card.
- However, if you are using another network you may delete this network icon. I would suggest you to follow the steps given below and check. 1) Open Network Connections by clicking the Start button, clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center. 2) Click on Change adaptor settings. 3) Right click on.

| Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier. |
The amplification factor, also called gain, is the extent to which a device boosts the strength of a signal.
The damping factor, also called loss, is the extent to which a device reduces the strength of a signal.

In analog audio engineering we deal only with 'voltage' amplification (gain) and damping (loss).
| V1 = Vin and V2 = Vout V2 > V1 or Vout > Vin means amplification. The dB value is positive (+). V2 < V1 or Vout < Vinmeans damping. The dB value is negative (−). V2/V1 or Vout/Vin means the ratio. The amplification or the damping in dB is: L = 20 × log (voltage ratio V2 / V1) in dB. V1 = Vin is the reference. |
In physics, attenuation is regarded as a positive value.
This naturally leads to sign errors when entering numbers. How do i open disk utility on my mac.

| 6 dB ≡ | 2 times the voltage | (−)6 dB ≡ | damping to the value 0.5 |

| 20 dB ≡ | 10 times the voltage | (−)20 dB ≡ | damping to the value 0.1 |
| Using voltage we get: Level in dB: L = 20 × log (voltage ratio) |
| 6 dB = twice the voltage 12 dB = four times the voltage 20 dB = ten times the voltage 40 dB = hundred times the voltage |
If we consider audio engineering, we are usually not interested in power.
Do not ask what power amplification means.
Leave that to the telephone companies or the transmitting aerials (antennas).
Power gain is really not used in audio engineering.
Do we really need power (energy) amplification?
Read the text at the bottom.
| 3 dB ≡ | 2 times the power | (−3) dB ≡ | damping to the value 0.5 |
| 6 dB ≡ | 4 times the power | (−6) dB ≡ | damping to the value 0.25 |
| 10 dB ≡ | 10 times the power | (−10) dB ≡ | damping to the value 0.1 |
| 12 dB ≡ | 16 times the power | (−12) dB ≡ | damping to the value 0.0625 |
| 20 dB ≡ | 100 times the power | (−20) dB ≡ | damping to the value 0.01 |
Using power we get: Level in dB: L = 10 × log (power ratio)

The voltage is always given as RMS value - but that is not valid for electric power.
There is also the reference power P0 = 1 milliwatt or 0.001 watt ≡ 0 dBm
Level in psycho acoustics as subjectivly perceived loudness (volume)The vague human feeling of the double loudness (volume) is specified
with about 6 to 10 dB. This personal feeling is not an exactly measurable value.
