Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . Sound waves carry energy that can be used to do work, like forcing the eardrum to vibrate.. The energy can be great enough to cause damage to windows and buildings (sonic boom). Sound Intensity. The amount of energy transported per second by a sound wave is the . An old riddle ….. If a tree falls in a forest, and no one hears it, does the tree make a sound?. What is “sound”?. Sound Waves. To a scientist, a tree makes a sound whether someone hears it or not.. REFLECTION OF SOUND. The reflection of sound follows the same laws as the reflection of light. Angle of incidence=Angle of Reflection. Sound waves can be reflected by hard/solid surfaces.. Example: Walls, Buildings and Cliffs. When discussing sound, several categories can be included:. Diegetic sound. Non diegetic sound. Dialogue. Voice-over. Music. Special effects. Silence. Sound motifs/themes. Two most important categories of sound:. Wave. particles vibrate parallel to the direction of the motion of the wave. Terminology. Compressions. : areas where particles come closer together. Rarefactions: . regions where particles are further apart. Remain as quiet as you can for 1 minute.. I will tell you when to begin, and when to stop.. In the margin of your paper, write down all of the different sounds that you hear in the environment around you.. What’s That Sound?: A Comparison of Sound Absorption of Different Commercial Flooring Which material has the most substantial absorption when exposed to various sound variations? Of the variables that are to be tested, carpet will be the one to have the greater absorption due to its characteristics of not being solidified by its padding, softness, and flexibility.
