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。

The complex pressure field resulted from a high-speed train entering a tunnel was investigated based on the theory of aerodynamic sound.

应用气动声学理论对高速列车突入隧道引起的复杂压力场进行了研究。

Methods Measurement of voice signal was made using micro-computer and acoustic software during sustained phonation of vowel /a/ in 50 healthy subjects and 50 patients with benign vocal fold lesions.The harmonic waves,formants and noise of the sonogram were analysed. Results There were significant differences of acoustic characteristics between normal and pathologic groups.
