Orr was breathing rhythmically with a noise that was stertorous and repulsive.

It had something to do with his stertorous, slightly nasal-breathy way of speaking: a vocal tic to compare with De Niro or Brando.

The unnerving sound of human breathing, at times gasping and stertorous, threads through it, before becoming the work's own death rattle as the music ebbs away.

The Rolls-Royce gave a faintly stertorous sigh and began to move.
