  The recently released BOOMERanG data was taken as ``contradicting topological
defect predictions''. We show that such a statement is partly misleading.
Indeed, the presence of a series of acoustic peaks is perfectly compatible with
a non-negligible topological defects contribution. In such a mixed perturbation
model (inflation and topological defects) for the source of primordial
fluctuations, the natural prediction is a slightly lower amplitude for the
Doppler peaks, a feature shared by many other purely inflationary models. Thus,
for the moment, it seems difficult to rule out these models with the current
data.
