Send me the reference value (0 dB) for frequency.
The decibel (abbreviated dB) is the unit used to measure how loud a sound is. The decibel scale is a little odd because the human ear is incredibly sensitive. Your ears can hear everything from your fingertip brushing lightly over your skin to a loud jet engine. In terms of power, the sound of the jet engine is about 1,000,000,000,000 times more powerful than the smallest sound that your ears can just barely hear. That's a big difference!On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB140 dB airplane taking off150 dB firecracker157 dB balloon pop162 dB fireworks (at 3 feet)
No, 10 dB is perceived to be twice as loud, and requires 10 times the power.Doubling of the volume (loudness) should be perceived by a level difference of 10 dB − psychoacousticians say.Doubling the sound pressure (voltage) level corresponds to a measured level change of 6 dB.Doubling of acoustic power (sound intensity) level corresponds to a calculated level change of 3 dB.Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?"
no

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.

The enharmonic equivalent of Db is C#. Both notes have the same pitch but are spelled differently.

I think 1 volt/bar when expressed in db you need to add 200 db to get reading in volts per micro pascal.
The fraction equivalent to 68 is 68/1. This is because any whole number can be represented as a fraction by placing it over 1. In this case, 68 can be written as 68/1, which is equivalent to the whole number 68.
80 dB is equivalent to 108 times the threshold of hearing. Usually 10 decibel will be the virtual silence. 80 dB will be equivalent to door slamming.
68 = 1000100 in binary.
Sounds from 90 db and up can eventually damage hearing. but 95db is equivalent to a subway train from 200 feet.
68/1 6/8 = 3/4
No.
68/100, when simplified, is equivalent to 17/25.
