This play by Nobel laureate O'Neill centers around Anna, a young woman who, after an illness, decides to spend some time with the father she knows only from occasional letters. While with him, a coal barge captain, she meets Matt, a sailor who's ready to settle down, and the two fall in love. Believing herself unworthy of happiness, Anna reveals secrets from her past that test both her father's and Matt's love. In this expert production, scenes are painted through dialog and the unobtrusive use of sound effects. The actors reveal vivid and distinct characters, and the listener never has to wonder who's speaking. Highly recommended to libraries that serve students and those who love theater.
The manual describes the author's system of words in blocks of harmony, as well as the classification of words meaning a minimum of English. This system allows not only easy to learn to read and memorize the words, but also develop the ability to create their own sound and semantic association, that is an integral part of thinking in English.
Disney Educational - Bill Nye The Science Guy: Sound
This episode of the Bill Nye the Science Guy series is noisier than usual, as the Science Guy talks about the science of sound. He discusses the waves that carry sound to human ears, making examples of school bells and stereo speakers. Nye inserts his trademark humor and parody into the scientific discussion to create a fun learning atmosphere.
Here is an original and exciting look at the fascinating world of sound and music. Superb real-life photographs of instruments ranging from zithers and panpipes to electric guitars and synthesizers offer a unique "eyewitness" view of ancient and contemporary music. See how strings vibrate to make a note sound, how sousaphone players wear their instruments. Learn who invented an important new key system, how to master the bagpipes, why pipe organs have "ears" and "mouths", and why French horns are "doubled up". Discover why tangled fingers led to the invention of the piano, why spiders add a "buzz" to xylophones, where reindeer toe-bones were used as whistles, and much, much more.
Sound source localization is an important research field that has attracted researchers’ efforts from many technical and biomedical sciences. Sound source localization (SSL) is defined as the determination of the direction from a receiver, but also includes the distance from it. Because of the wave nature of sound propagation, phenomena such as refraction, diffraction, diffusion, reflection, reverberation and interference occur. The wide spectrum of sound frequencies that range from infrasounds through acoustic sounds to ultrasounds, also introduces difficulties, as different spectrum components have different penetration properties through the medium.
