Document Summary
Chapter 2 cont: 2 out of 3. If you get 15, come back and get 15 again, that is 2 out of 3 and is greater than: hearing sensitivity is a fancier way of saying hearing. Hearing sensitivity refers to the ability to detect faint sound. Threshold faintest level at which a sound is heard 50% of the time it is presented. Minimum audibility curve graph of hearing sensitivity in db spl re: 20 upa for the average. Audiogram graphic representation of the threshold of audibility across the audiometric. It is a plot of absolute threshold, designated in db hl. On an audiogram what would you record? db. If the graph to the right is shown, y is graphed db spl. Audiometric zero: for clinical purposes, the minimum audibility curve (db spl) is converted into 0 db hl for each frequency. If the image to the right were on an exam, proff.
