Hi all, http://www.a3ccm-apmas-eakoh.be/welcome.htm http://www.a3ccm-apmas-eakoh.be/index.htm I found this interesting. Does anyone know if there is more recent information? It explains the origin of hyperacusis in a different way. It also explains cochlear amplification in a different way. I haven't read all of it yet, but I am going to. Is there already a thread on this forum regarding this theory? I couldn't find it.
