PPT-Sound Reflection and Sound Absorption

REFLECTION OF SOUND The reflection of sound follows the same laws as the reflection of light Angle of incidenceAngle of Reflection Sound waves can be reflected by hardsolid surfaces Example Walls Buildings and Cliffs. Presented by. :. Panos. Economou. P.E. . Mediterranean Acoustics Research and Development. , Cyprus. . Panagiotis. . Charalampous. . P.E. Mediterranean Acoustics Research and Development, . Cyprus. Essential Question:. How are sound waves . affected by medium?. Let’s Review Sound Waves. A Sound wave is a mechanical wave because it has to travel through a medium.. A Sound wave is also a Compressional wave because matter in the medium moves forward and backward along the same direction that the wave travels.. Reflection. When a wave reaches a boundary between two media, usually some or all of the wave bounces back into the first medium.. A metal surface is rigid to light waves that shine upon it. . Light . Essential Question:. How are sound waves . affected by medium?. Let’s Review Sound Waves. A Sound wave is a mechanical wave because it has to travel through a medium.. A Sound wave is also a Compressional wave because matter in the medium moves forward and backward along the same direction that the wave travels.. Wave Properties. There are 6 main properties, or interactions, of waves that occur when a wave comes in contact with another wave , or a boundary. . The 6 Interactions of waves are. Interference. Diffraction. Use your knowledge of waves & physics to answer the question.. Sound. Longitudinal wave phenomenon that consists of successive compressions and rarefactions of the medium through which the wave travels. . 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. 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. Kris Gill. What is Sound Absorption?. . Any technique used to manage the reflection of sound off of a surface. causing sound energy to be dissipated.. Absorption. Reflection. Diffusion.

Prof. D. M. . Parshuramkar. Dept.. Of Physics. N. H. College, Bramhapuri. Introduction. . Acoustics. It is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.. What makes sound:. . Vibration makes sound. When you talk it causes vibrations which goes to the other persons ears. . . How does sound travel?. Sound travels with sound waves. .
