The decorrelation frequency f(nu) and decorrelation time t(nu) are measured for 15 pulsars. It is shown by combining the present data with those of others that f(v) varies as DM to the -1.79 + or - 0.14 and t(v) varies as DM to the -0.80 + or - 0.15 up to a dispersion measure (DM) of about 60 pc/cu cm. The combined data set does not form a complete sample, but the relations obtained from measurements on 14 pulsars, which form almost a complete sample up to 41 pc/cu cm, are consistent with the above relations, suggesting that these relations are not seriously affected by selection effects. The relations are broadly in agreement with those expected from a homogeneous interstellar medium and are in disagreement with earlier conclusions that these relations steepen even for low-DM pulsars. The agreement suggests that the local interstellar medium is homogeneous at least up to a distance of about 2 kpc.
