A sound of 20 dB intensity is twice as loud as one of 10dB?
This statement is not accurate. The decibel (dB) scale is logarithmic, not linear. An increase of 10 dB represents a tenfold increase in sound intensity. So, a sound of 20 dB intensity is actually 10 times louder than one of 10 dB, not twice as loud.
How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

How does intensity of a 40 decibel sound compare to intensity if a 20 decibel sound?
The intensity of a 40 decibel sound is 100 times greater than that of a 20 decibel sound because every increase of 10 decibels represents a 10-fold increase in intensity.
Determine the Dynamic range for a 10-bit sign-magnitude PCM code?
Using DR(db) = 1.76 + 6.02(n), where n = 10, will have an answer of 61.96 dB Using the another formula, DR = 2^n - 1; DR = 2^10 - 1 = 1023 Getting the DR(db) = 20log(1023) = 60.2 dB
How do you converts ohms to dB?
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
What is 45 percent in decibels?
100 percent is 0 dB.50 percent is - 6 dB.45 percent is -6.935749724 dB.10 percent is - 20 dB.
What is dB in Electronics Engineering?
Deci-bels (dB) are a logarithmic measure of system/network amplification or gain (G). The logarithms are taken to the base 10 and multiplied by 20:dB = 20logG (where G is the gain of the system)To give an example of what this means:G = 0.01, so dB gain = 20log0.01 = 20 * -2 = -40dBG = 0.1, so dB gain = 20log0.1 = 20 * -1 = -20dBG = 1, so dB gain = 20log1 = 20 * 0 = 0dBG = 10, so dB gain = 20log10 = 20 * 1 = 20dBG = 100, so dB gain = 20log100 = 20 * 2 = 40dBG = 10000, so dB gain = 20log10000 = 20 * 4 = 80dBThere are other uses for dB in electronics, where logarithms are useful they are preferred. The reasons logs can be useful is because the natural log of an exponential curve is a straight line, allowing for easier ways of understanding the behaviour of a system.
Compared to a close whisper at 20 dB. How many times more intense is a normal conversation at 60 dB?
A normal conversation at 60 dB is 1,000 times more intense than a close whisper at 20 dB. This difference is due to the logarithmic nature of the dB scale, where each 10 dB increase represents a tenfold increase in intensity.
How do you convert db to mw?
To convert from dB (decibels) to mW (milliwatts), you can use the formula: mW = 10^(dB/10). Simply take the dB value and divide it by 10, then raise 10 to that power to get the mW value. For example, if you have 20 dB, the calculation would be mW = 10^(20/10) = 100 mW.
If sound A has an intensity that is 100 times that of sound B then how many dB's higher is sound A?
Sound A would be 20 dB higher than sound B. Sound intensity level (in dB) increases by 20 log (I1/I2) when the intensity ratio changes by a factor of 10. Since A is 100 times greater than B, the dB difference would be 20 log (100) = 20 dB.
How much louder is a sound wave that has an intensity of 50 dB than a sound wave with an intensity of 20 dB?
A sound wave with an intensity of 50 dB is 1,000 times louder than a sound wave with an intensity of 20 dB. This is because every increase of 10 dB represents a 10-fold increase in intensity.
