hss works by mixing regular, audible sound with two beams of super high frequency, inaudible sound waves. 「just the way artists mix their paint, 」 says norris.
是通过混合有规律的,个超高频率的声音柱的可听到的声音,听不到的声音工作的。「就是一种艺术家混合他们的颜料的方法,」
audible sound simulation usually includes room sound simulation, binaural signal simulation and similarity simulation.
常用的模拟方法可分为:厅堂模拟、双耳模拟和相似模拟三种。
a semivowel, one having an audible sound by the addition of another letter; e. g. s and r.
半元音是由另一个字母辅助才能够发出声音的字母,比如s或r;
their message can be read much more easily than if they uttered an audible sound ;
整个宇宙向人类所发出的无声信息比人类耳朵能听见的有声信息更容易读的懂;
the problems which audible sound simulation wants to solve are how to determine a sound field and how to restructure a sound field.

the former being based on the scattering of sound waves from 「micro-structure」 of atmosphere deals with active sensing for audible sound mainly;
后者以次声的被动遥感为主,其基础是大气「宏观结构」对声波的折射。
a novel audio beam loudspeaker which based on nonlinear propagation effects of ultrasonic in the air to generate audible sound with high directivity is presented.
提出了一种利用空气中超声波非线性传播效应制作的、可产生高指向性可听声的新型声束扬声器。
on top of this, audible sound coming from large loudspeakers has large wavelengths, ranging from a few inches to several feet, making it easier for sounds to travel in all directions.
除此以外,大型扩音器发出的听得见的声音波长较长,从几英寸到几英尺,方便声音向各个方向传播。
