The sound becomes harder to hear. Unless you are above the threshold of pain in which case I guess the sound becomes easier to hear. The decibel system was designed so that the thresold of human hearing is just about at 0 dB and the threshold of pain is at about 135dB0. Where the power doubles for every 3 dB points. Hence it is a logarithmic scale. A 20dD sound is not half as loud as a 40dB sound but roughly 100 times quiter.
