In the list, there are sounds ranked by loudness. Sound is measured in decibels. Decibel scale is logarithm and relative, not linear. Relative means that dB is only a useful measurement when compared to other dB values. Logarithm means 10 dB is 10 times louder than 0 dB and 20 dB is 10 times louder than 10 dB and 100 times louder than 0 dB. But humans feel 10 dB is twice as loud as 0 dB and 20 dB as twice as loud as 10 dB and four time loud as 0 dB. Since decibel scale is logarithm and relative, it is limitless on both directions and doesn't stop at 0 dB. But in practice, a human will rarely be able to hear a sound between 0 and 10 dB.
