Subject: impedance demonstrations From: "Ferguson, Sarah Hargus" <safergus@xxxxxxxx> Date: Fri, 3 Feb 2006 10:06:13 -0600Hello list - In my undergraduate introduction to audiology course, I do one lecture on tympanometry and acoustic reflexes (they get to do them in lab as well). Does anyone have any suggestions for low-tech hands-on activities that the students could do in class that would illustrate impedance, such as how increased impedance in the middle ear leads to higher probe tone levels in the ear canal? I have some thought experiments that I lead them through, but something tangible would be better. On-line video demonstrations would be great too... ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Sarah Hargus Ferguson, Ph.D., CCC-A Assistant Professor Department of Speech-Language-Hearing: Sciences and Disorders University of Kansas Dole Center 1000 Sunnyside Ave., Room 3001 Lawrence, KS 66045 office: (785)864-1116 Speech Acoustics and Perception Lab: (785)864-0610 http://www.lsi.ku.edu/ipcd/FAC/Bios/FergusonBio.html
