What is the Welsh for 'decibel'?
The Welsh word for 'decibel' is desibel.
Convert signals from voltage levels to corresponding decibel equivalents?
To convert voltage levels to DB you must first specify a reference, then take 20 x log(base 10) of the ratio of the voltage level in question to the reference. For example, if the reference is 1 volt and the signal of interest is 100 volts, then the level in dbV is: 20 x log10 ( 100 / 1 ) = 40 dbV

A bar chart showing the loudness in dB of different activities?
A bar chart can provide a visual representation of the loudness in dB for activities such as concerts, traffic noise, and normal conversation. Each activity can be represented by a labeled bar with corresponding dB levels on the y-axis, giving a clear comparison of their loudness levels. This chart helps easily understand the differences in loudness between various activities.

Convert signals from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
This question contains a fundamental misunderstanding of a decibel.A decibel (always shortened to db or dB ) is not a level ; it is a ratio between two levels.The ratio is not voltages either - it is a power ratio. A power ratio can be converted to a voltage ratio if you understand Ohm's law and if the circuit impedance is the same for both measurements.To convert a power ratio to dB, take the log of the ratio (to base 10) then multiply by ten. In figures, if ratio is x, calculate 10 log10 (x)examples:if power ratio is 10, log(10) is 1, = 10 dBif power ratio is two, log(2) is .3010, = 3dB.power ratio 100, 20 dB, 1000 30 db and so on.It does sometimes seem that db figures are used to define levels. You need to look closely to see how this magic works.23 dbW is 200 Watts. Because dbW means db relative to 1Watt. More common in electronics is dbm - relative to a milliwatt.Warning. If you are interested in voltage levels, remember that a 6db increase in power is 4 times the power, but only twice the voltage.And why is it sometimes dB ? Well, the original scientific unit was the Bel. This was an inconveniently large unit, so engineers started using the deciBel, one tenth of a Bel. Nowadays db seems to be more common than dB.
What is the subunit of Decibel?
The bell is a large unit, so a subunit, a decibel, is usually used. There is no subunit of decibel.
