Subject: New version of TEN test From: "Brian C. J. Moore" <bcjm(at)CUS.CAM.AC.UK> Date: Tue, 25 Nov 2003 18:34:01 +0000 X-Cam-ScannerInfo:http://www.cam.ac.uk/cs/email/scanner/Dear Colleagues, Those of you who work on hearing impairment may interested in a new version of the TEN test for diagnosis of dead regions in the cochlea. The new TEN test has the following advantages over the original version: (1) All levels are expressed in dB HL. Thus, absolute thresholds only need to be measured once. (2) Calibration is such that both the noise level/ERB and the test tone levels correspond to the values indicated on the audiometer. This makes the test simpler to apply, and reduces the likelihood of errors. (3) The noise bandwidth is restricted, and the noise has a low crest factor. This allows the noise level/ERB to be increased while avoiding distortion, excessive loudness, and possible further damage to hearing.
