Loudness Normalization ! MLA and different genres. When older recordings are included in a playlist with new material, the lis-tener experiences noticeable jumps in loudness from track to track requi 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. Presented by . Vinoth. . Kulaveerasingam. QMUL ELE021/ELED021/ELEM021 • 5 Mar 2012. Paper by . Jorg. . Langner. and Werner . Goebl. Visualizing Expressive Performance in Tempo-Loudness Space. What is the aim?. How to Guide How to Guide Audio Loudness Monitoring www.tektronix.com\wfm8000www.tektronix.com\wfm7100www.tektronix.com\wfm5200 for Audio Loudness measurements to the ITU-R BS.1770 standa Loudness Scaling Loudness Scaling Thomas Brand Medical Physics, University of Oldenburg Introduction Categorical loudness scaling determines the loudness in the whole auditory dynamic range in terms 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!. Measurements. . Measurements help us describe the world and everything in it.. Measurements can describe length, volume, weight, time, temperature, and countless other properties.. . Standardized Unit System. 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!). 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!). 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.. 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. Which statement accurately describes the mathematical relationship between the intensity of a sound and the decibel rating? A . number. A . unit. Example: . 5. cm. Scientists (and we will) use the SI system. Système. International . d’unités. The SI units = METRIC. There are only 3 countries in the whole world using the ENGLISH SYSTEM of measurement.
