Write a C# program that reads a value and a unit, either dB or Pa, and then prints the closest description from the list below.

Sound level L in units of decibel (dB) is determined by L = 20 log10(p/p0)  where p is the sound pressure of the sound (in Pascals, abbreviated Pa), and p0 is a reference sound pressure equal to 20 x10–6 Pa (where L is 0 dB).
The following table gives descriptions for certain sound levels.

Threshold of pain Possible hearing damage Jack hammer at 1 m Traffic on a busy roadway at 10 m Normal conversation Calm library Light leaf rustling 130 dB 120 dB 100 dB 90 dB 60 dB 30 dB O dB
