Re: Individualized HRTF measurements

[Brian FG Katz <brian.katz@xxxxxxxx>]

Dear Thibaud,

I encourage you to look at the various publications related to the numerous HRTF databases. These often give clear and detailed descriptions of the systems employed. 

For a summary, or leads, of a number of systems, you can start here:

• Andreopoulou, D. R. Begault, and B. F. Katz, “Inter-laboratory round robin HRTF measurement comparison,” IEEE Journal of Selected Topics in Signal Processing, vol. 9, no. SI: Spatial Audio, pp. 895 – 906, 2015, doi:10.1109/JSTSP.2015.2400417.
• Katz and D. Begault, “Round robin comparison of HRTF measurement systems : preliminary results.,” in 19th Intl. Cong. on Acoustics (ICA 2007), (Madrid, Spain), pp. 1–6, 2007.

In France, I courage you to contact IRCAM and Orange Labs, as they both have fully functioning HRTF measurement systems. 

Cordially,

-Brian FG Katz

Objet : Individualized HRTF measurements

Dear List,
 
I intend to carry out some individualized HRTF measurements. I thought some device would exist in purpose of such measurement by including tiny microphones and a system to maintain their position into the ear canal but I feel more like each team uses its “homemade” setup… I only saw a “binaural microphone” designed by Bruel and Kjaer which is very expensive.
 
I was then wondering what microphone do you use/propose/advice  for individualized HRTF measurements ? Do you also know a way to hold the microphone in position during the measurement procedure ? And finally, do you use any type of protection in between the microphone and the ear canal in order to avoid a direct contact and then get the measurement more hygienic (given that the microphones will inserted in several subjects’ ear canals…) ?
 
Any help or advice on these matters would be very appreciated.
Thank you very much by advance,
 
Thibaud LECLERE
