You will implement a feedback-echo effect and adjust its parameters in real time with a MATLAB graphical user interface.
You will implement three audio effects: a fixed-length delay, a variable-length delay, and a feedback-echo. All require storing many samples in external memory.
This module shows how to implement the echo and reverberation effects using the DSK6713. The effects are simulated using Simulink. Those simualtion models are used to generate the DSP code for the real-time implementation.
In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.
Students model and design the sound environment for a room. They analyze the sound performance of different materials that symbolize wallpaper, thick curtains, and sound-absorbing panels. Referring to the results of this analysis, they then design another room based on certain specifications and test their design.
traces the evolution of this Maryland site from a chapter of the Chautaqua movement, to an amusement park, to a national park.
Describes active sonar echo, direct blast and reverberation generation.
In this lesson, students learn about echolocation: what it is and how engineers use it to "see" things in the dark, or deep underwater. Also, they learn how animals use echolocation to catch their dinner and travel the ocean waters and skies without running into things.
Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.
This is the last of five sound lessons, and it introduces acoustics as the science of studying and controlling sound. Students learn how different materials reflect and absorb sound.
Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theaters
