The Viking HRTF dataset v2

Simone Spagnol; Riccardo Miccini; Runar Unnthorsson

The Viking HRTF dataset v2 is a collection of head-related transfer functions (HRTFs) measured at the University of Iceland. It includes full-sphere HRTFs measured on a dense spatial grid (1513 positions) with a KEMAR mannequin with different pairs of artificial pinnae attached. The artificial pinnae were previously obtained through a custom molding procedure from different lifelike human heads (courtesy of Ernst Backman, Saga Museum Reykjavík).

An overview of the methods and procedures of the HRTF measurement sessions can be found in the papers

A first version of the dataset has been released in May 2019. In this second version, the used artificial pinnae were re-casted from the existing inverse molds with 35 Shore OO silicone for both the left and right channels of the KEMAR. Furthermore, the HRTF measurements have been taken inside the anechoic chamber of the University of Iceland in Reykjavík and free-field compensated.

The dataset, available in SOFA format, contains measurements for 20 different pairs of articial pinna replicas (subjects A to T, where T is a pair of standard large KEMAR anthropometric pinnae replicas) plus a pair of flat baffles simulating a "pinna-less" condition (subject Z).

3D scans of the 20 left pinna replicas are available as STL files. The scans were captured at 1mm resolution with a Creaform Go!SCAN 20 (courtesy of AAU Create Prototyping Lab).
