Logarithm CORRECT ANS-is the exponent of base 10 that equals the value of a number
Decibel CORRECT ANS-describes a base-ten logarithmic relationship of a power ratio
between two numbers.
-It uses a logarithmic scale to describe ratios with a very large range of values that can vary
over several orders of magnitude.
-It is also used for quantifying differences in voltage, distance and sound pressure as they
relate to power.
Decibels can measure what type of values? CORRECT ANS-Distance, Power, Pressure, or
Voltage
Pascal CORRECT ANS-SI Unit for Pressure
Decibel Formula for Power CORRECT ANS-dB = 10 * log (P1 / Pr)
Where:

dB = The change in decibels
P1 = The new or measured power measurement
Pr = The original or reference power measurement
if result is positive, the result is an increase, or gain. If it is negative, the result is a decrease,
or loss.
Decibel Formula for Distance CORRECT ANS-dB = 20 * log (D1 / D2)
Where:
dB = The change in decibels
D1 = The original or reference distance
D2 = The new or measured distance
This as the same as:
db= 10 * log (D1²/D²)
