PPT-Sound Intensity Sound Intensity

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 . Nature of the Sound Stimulus. “Sound”. . is the rhythmic compression and decompression of the air around us caused by a vibrating object.. Applet. Applet2. Sound Wave:. Amplitude and Frequency (Hz). . How is sound produced, how does it travel through the air and how do we hear sounds?. Sound II. As the vocal chords vibrate, the air is alternately compressed and rarefied resulting in a longitudinal pressure wave. Physics - Arrowhead. Mr. Streufert. 2013-14. Learning Targets. Apply wave concepts to the physical and perceived characteristics of a sound wave. Perform calculations involving speed and intensity. Detect audibility and harmonic relationships. i. mpact . loud. speaker . upon. . particle. distribution in the air. sound amplitude . depends. . on. . variation. of sound . pressure. modulation. of . atmospheric. . pressure. = 100.000 Pascal. Check last week’s homework. Sound Waves – some vocab. Each . cycle. of a sound wave includes one . condensation. and one . rarefaction. The . frequency. of the sound wave is the number of cycles per second that pass by a given location. Sound Intensity, Sound Level/Loudness (Decibels), The Ear. 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. By Rhett Price. Speed of Sound . Speed of sound depends on density. Correlation between speed and density. Not as fast as light speed. Also affected by pressure and temperature. Positive correlation between them. http://www.youtube.com/watch?v=a3RfULw7aAY&feature=related. . An . approaching source sounds higher in pitch than the source.. A . source that is moving away sounds lower in pitch than the source.. 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!). Properties:. . Numbers:. . Sound intensity and power. Intensity:. P. – power (do not confuse with pressure). E . - . energy. t . - time. Free field (radiation is uniform in all directions):. r . Sound waves are made up of a series of regions of high and . low pressure. . The areas of high pressure are called . compressions. . The . areas . of low pressure are called . rarefactions.. Wave energy travels through the material. But a particular piece . PROGRAM. 1. 28 Jan 2013. Learning Objectives. Explain the parameters of sound and how they are measured. Apply the parameters of sound to the sensitivity of the human ear. Apply the parameters of speech and sound to an audiogram. While ordering the most unique FL studio sound packs plus sound files you will have to search the best sound agency sites of product galleries. As a leading music producer you will need to look for the most exclusive sound buy options for creating the best musical albums.
