Subject: Re: Hearing Loss "False Positives" From: Jeffrey Willson <willsonj@xxxxxxxx> Date: Thu, 23 Sep 2010 14:01:22 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--0016364ede86519d740490f1e3a8 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable I think you're misreading this. The paper says that a reasonable statistical model reveals that the method used in previous studies will fin= d roughly 10% of children with normal hearing to have a measured hearing loss that isn't real. You subtract that from the 14.9% figure and you get less than 5% of children with high-frequency hearing loss, and probably the majority of these are from causes other than loud noises.
