The radio was on at full blast.

【blast】收机开到量。

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， 开足马力播放。

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

它加快的速度——整个身体都在全速咆哮， 就像一个口开的熔炉。
