Frequency - number of cycles per second (1/Period). SOUND IS…. (for our purposes). Movement of the air that happens at human hearing frequencies:. 20 - 20,000 cycles per second. The easiest case to imagine is a “monopole” sound source.. Imagine a ball suspended in the air that expands and contracts, pushing and pulling on the air around it.. Tine . Gulbrandsen. Wahab. .

Virtually all sounds are composed of several (or many) frequencies all going at once. Have your science notebook out ready to take notes. Grab the sheet from the front. Brainstorm everything you currently know about sound. Be ready to share. . Sound Vibration. Is a wave that vibrates particles of matter. 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. phon. , and is arrived at by reference to equal-loudness contours. By definition two sine waves, of differing frequencies, are said to have equal-loudness level measured in phons if they appear equally loud to the average young person without significant hearing impairment.. 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. 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. By Robin Richardson. If you wish to understand the Universe, think of energy, frequency, and vibration. ---.
