isochronal

There was something indescribably grim and bodeful in those isochronal batterings of the solid ground.

A trombone blatted—there was the staccato tuck of a snare drum, and the boom of a bass drum came in with isochronal beats.

Isochronal, ī-sok′ron-al, adj. of equal time: performed in equal times—also Isoch′ronous.

It is often supposed that hairsprings having exactly even coils are correct for close position and isochronal rating.

Experiment will demonstrate that watches carefully adjusted to positions will also have a very close isochronal rate.
