This article concerns the realization of two sound installations that use a parametric (directional) loudspeaker as a central element of their working systems. The Soundhouse is a rotating structure that projects sounds in a directional way. El bosque y las sombras is instead an interactive multimedia setting where the visitors can trigger sounds and affect a video projection by moving in an enclosed, soundproofed space. A short introduction to parametric loudspeakers is provided; then the concept and the construction aspects of both installations are presented. Finally, an overall aesthetic assessment of the use of parametric loudspeakers in the above works is given.

声音直接：两个音景装置中的参数扬声器

本文涉及使用参数（定向）扬声器作为其工作系统的核心元素的两个声音装置的实现。Soundhouse 是一种旋转结构，以定向方式投射声音。El bosque y las sombras 是一种交互式多媒体设置，游客可以通过在封闭的隔音空间中移动来触发声音并影响视频投影。提供了参量扬声器的简短介绍；然后介绍了这两个装置的概念和构造方面。最后，对上述作品中参量扬声器的使用进行了整体的审美评估。
