声学的

There are two basic types of acoustic treatment - absorbers and diffusors.

有两个基本类型的声学处理-吸收和扩散。

That isn't to say that Linstead plays the acoustic guitar exclusively on-stage or in the studio; while the acoustic guitar is his primary instrument, Linstead also plays mandolin, violin, bass, acoustic piano, electric keyboards, various wooden flutes, and the bouzouki (a traditional Greek string instrument).

这就是说，Linstead只在舞台上或录音棚里演奏非电声吉他；虽然非电声吉他是Linstead主要演奏的乐器，他也演奏曼陀林、小提琴、贝斯、声学钢琴、电声键盘、各种木笛，以及布祖基琴。
