Subject: Headphone to ear canal Transfer Function From: =?ISO-8859-1?Q?Sergio_Rodr=EDguez_Soria?= <sergio(at)LPS.USP.BR> Date: Mon, 1 Nov 2004 16:56:41 -0300Dear list members, I work with HRTF models and in the next months need to do some listening tests in order to validate the models. Normally I don't take into account the headphone to ear canal Transfer Function (which includes the headphone transfer function). Is that very important for reproducing virtual sound through headphones? If it is so, I will need the headphones free-field transfer function (for compesating just the headphones), and/or, if there exists in public domain, the headphone to ear canal transfer function (for compensating the headphones and the transmission path between the headphone's output and the ear canal entrance - given that the HRTF model reproduce the transmission between the "free field" and the ear canal entrance). Do I am right? Does anyone know about a public database for these kind of signals? Besides of that, what headphones are recommended for these tests?
