What sound level is dB is required for a 1 sone loudness at frequency 50 Hz?
1 sone = 40 dB at 1 kHz.
An increase of 20 dB increases the sound intensity by a factor of?
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')
How many dB of attenuation translates into 50 percent of the voltage being lost to attenuation?
db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02
How do you convert kHz to hertz?
kHz means 1000 hertz. To convert from kHz to hz, multiply the number of kHz by 1000 and the product will be in hertz.
What is gained?
The process gain (or 'processing gain') is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).For example, if a 1 kHz signal is spread to 100 kHz, the process gain expressed as a numerical ratio would be 100,000/1,000 = 100. Or in decibels, 10log10(100) = 20 dB.

What sound level is dB is required for a 1 sone loudness at frequency 50 Hz?
1 sone = 40 dB at 1 kHz.
How loud you can be?
100 dB
How loud is a avalanche in decibels?
A avalanche can range from 100 dB to 180 dB
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.

Is a sound that measures 100-dB ten times louder than a 10-dB?
90

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.
How many time more is the orchestra than the soloist if the orchestra has a sound intensity of 90 db and the soloist has a sound intensity of 70 db?
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')
What is used as switching element in SMPS at 20-100 kHz?
MOSFET
