Using a vibrating reed technique, internal friction (Q -1 ) and Young's-modulus sound velocity (VE) were measured for polycrystalline samples of two types of superconducting Pbo.75Cuo.2s(Sro.9Cao.l )2(Yo.5Cao.5)Cu207+6 (Tc= 58 and 48 K) and insulating Pbo.sCuo.sSr2YCu207 in the temperature range bet
