Lots of mass (very low resonant frequency)
Low stiffness (very high co-incident frequency)
All materials have both a resonant and co-incident frequency, at which sound is transmitted more efficiently. Materials where these frequencies occur outside of the range of hearing (20 - 20,000 Hz) are better for sound proofing.
With lead, the resonant frequency is below 20Hz and the co-incident frequency is about 20,000Hz.
