Noise in classrooms is usually generated within the classroom by the children and adults present.. Russell Stannard. Lecture 4 week 1. Flipped Classroom. Very hot topic. A movement that is taking place in the USA especially. Little research into this. Pressure coming from different areas. Idea is that we don’t need to lecture anymore. All the content can be put on line and we spend time with the students . Kaegan Gregory. Overview of Prior Research. Every concert hall is unbalanced. Acoustic engineers adjust acoustics in concert halls. Sound shells. Sound Reflectors. RCHS auditorium adjusted with sound reflectors. 5.1.9. You and I are standing next to each other, listening to the exact same steady sound. . Our ears are identical. . You listen for TWICE as long as I do. How does the (average) power compare? (Please average ONLY over the time that the individual is listening!). 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 . Sound waves are longitudinal!. Sound can be explained by understanding:. Speed. Intensity. . and loudness. Frequency and pitch. Most people hear sound between the frequency of 20Hz and 20,000Hz. . Anatomy of Sound. Producing and Detecting sound. What is sound?. The sound you hear is sound waves that can only travel through matter.. Sound waves are longitudinal waves. . Sources of sound. Every sound comes from a vibration, which is the energy that the wave uses to carry the 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. 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. Sound Chapter 12 Sound hunt 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. Sound is a . longitudinal. . (Mechanical)wave caused by a . vibrating. object.

Music is just a wonderful feeling that has the potential to blow our minds and we sometimes wonder what it takes to create this magic.
