The radio was on at full blast.

【blast】收到了最大量。

During the rare moments that the television was off, Dad would put on his old Elvis records and play them at full blast.

在很少有电视关掉的时候，爸爸会放他的旧猫王唱片， 足马力播放。

It speeds up the heart — the whole body is roaring away at full blast like a furnace with all its draughts wide open.

它加快了心脏的速——身体都在全速咆哮， 就像一大口大的熔炉。
