Subject: [AUDITORY] Independent of direction equalization From: Frederico Pereira <pereira.frederico@xxxxxxxx> Date: Tue, 22 Jan 2019 19:22:34 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--000000000000083b86058010e71e Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Dear list, I=C2=B4m implementing a matlab routine for the calculation of Loudness for = a non-stationary sound,(approaching vehicle) recorded with a Head and Torso Simulator, in accordance with ISO 532-1:2017. The standard refers to the Annex D, where a ID equalization (Independent of Direction) is suggested. Is there a standardized methodology for this ID equalization? I can=C2=B4t seem to find much about it...I understand it is = so to remove ear canal and conchae resonances. I also wonder if this would be the most suitable method to get a Loudness-Time plot of an approaching vehicle... Any tips would be of great help.
