BT-DEI – HpIR Database

Headphone Impulse Response database

The BT-DEI HpIR Database is a public-domain database of Headphones Impulse Response (HpIR) measurements for 3 different headphones and up to 24 different subjects, including the KEMAR mannequin with and without large pinnae.

SOFA SingleHeadphoneIR-0.1

Measurement setup in the SOFA convention SimpleHeadphoneIR

The database includes 10 measurements of headphone impulse responses for each headphones and subject. These measurements were recorded at the entrance of open and blocked ear canal, OEC and BEC respectively, with Soundman OKMII Classic in-ear microphones. All the measurements are stored in bt-dei format v. 0.2 (a Matlab based data format).

Starting from July 2014, the BT-DEI HpIR Database is part of the PHOnA dataset (Princeton Headphone Open Archive) that aims to make the large amounts of existing HpTF data publicly available to researchers worldwide.
