PPT-Pitch What is pitch? Pitch (as well as loudness) is a subjective characteristic of sound

Some listeners even assign pitch differently depending upon whether the sound was presented to the right or left ear Pitch characterize how high or low is sound Pitch is mainly but not only determent by the fundamental frequency. 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. of a series of preparatory lectures for the Fall 2013 online course MATH:7450 (22M:305) Topics in Topology: Scientific and Engineering Applications of Algebraic Topology. Target Audience: Anyone interested in . More Properties of Sound. Resonance. Definition: when a force is applied to an object in repeated motion at exactly the natural frequency, an increase in amplitude occurs.. Important points: force applied AT the natural frequency!. EQ: What are the properties of sound?. 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.. Sound is a compression wave - it only “looks” like a wave if we plot air pressure against time. time ->. Air Pressure. Period - amount of time for one cycle. Frequency = number of cycles per second (1/Period). 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 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. Audiogram or Audibility Function (AF) . for normal human young adult. Note: peak sensitivity 2-5K frequency range.. . Audiogram or AF. : . a graph indicating the threshold intensity of varying frequencies. A normal audiogram show declining threshold intensity from 20hz to about 2,500hz (where it usually bottoms out). Then a steady increase from about 5,000 to 10,000; with a very steep increase from 10,000 on. 1.
