Display of economical audiometer:
There are two output LED on both side of the display,when the selected detection |
Signal transfer to corresponding ear, the screen would show. During the audio detection,the up line of the display would show the strength that provide to left or right ear by dBHL ration |
When testing,the test ear would show"L" or "R" on the display. Test frequency wouldshow in the middle of the screen. If cover the opposite ear,it will show in the opposite side. |
