In other words, we have to increase it by 10 decibels why it's important that the conference phone at the receiving end has the power to handle this.

a logarithmic unit of sound intensity equal to 10 decibels ; Anagrams of bel BLE question?” When calculating decibels, we use the common logarithm, written as log, with its base value of 10. (The natural logarithm written as ln, uses a base value of e, which is 2.71828.) For example, if the number in question is 100, the base value of 10 would have to be raised to the power of 2 2to equal 100. i.e. 10 = 100. L'échelle des décibels L’intensité des sons est exprimée en décibels dans une échelle allant de 0 dB(A), seuil de l’audition humaine, à environ 120 dB(A), limite supérieure des bruits usuels de notre environnement. The difference in decibels between the two signals of power P 2 and P 1 is defined above to be ΔL = 10 log (P 2 /P 1) dB so, raising 10 to the power of these two equal quantities: 10 L/10 = P 2 /P 1 so: P 2 /P 1 = 10 110/10 = 10 11 = one hundred thousand million. Because sound pressure levels in decibels (dB) use a logarithmic scale we can't just add two dB readings together.

DECIBEL LEVELS MEANING: Decibel Effect: 0: Healthy hearing threshold 0-30 dB, Very Faint. Barely audible: 10: A pin dropping: 20: Rustling leaves: One-sixteenth as loud as 70 dB. Very Quiet: 30: Whisper, Soft music: 31-50 dB, Faint: 40: A babbling brook, Computer: One-eighth as loud as 70 dB. 50: Light traffic, Refrigerator: 46-70 dB, Average. One-fourth as loud as 70 dB. 60

dB-skalan är så kallad logaritmisk och det gör att en ökning från t.ex 50 dB till 100 dB inte ökar ljudnivån med det dubbla, utan mycket, mycket mer. Man kan säga att en ökning med 10 dB dubblar ljudnivån, vilket innebär att en ökning från 50 – 100 dB resulterar i att ljudnivån upplevs minst 5 gånger starkare.

- 6 dBm would be ¼ mW. A P(ratio) = 10 A P(Bel) Converting decibels into unitless ratios for power gain is much the same, only a division factor of 10 is included in the exponent term: If: A P(dB) = 10 log A P(ratio) Then: Example 1. Power into an amplifier is 1 Watt, the power out is 10 Watts. Find the power gain in dB.
