The sound attenuation exhibits a non-trivial dependence on the wavevector, with a remarkably rapid increase towards a Ioffe-Regel crossover as the frequency approaches the boson peak from below. An analysis of literature results reveals the near coincidence of the boson-peak frequency with a Ioffe-Regel limit for sound in {\\em all} sufficiently strong glasses. We conjecture that this behavior, specific to glassy materials, must be quite universal among them.","authors_text":"B. Ruffl\\'e, E. Courtens, G. Guimbreti\\`ere, G. Monaco, R.
