NC_GLOBAL.History: raw measurement NC_GLOBAL.References: NC_GLOBAL.Origin: http://www.hrtf.ircam.fr NC_GLOBAL.RoomShortName: IRCAM Anechoic Room NC_GLOBAL.RoomDescription: All measurements were performed in IRCAM's full anechoic chamber.\012This sound isolated cuboid-shaped room (room-within-a-room structure supported on neoprene mounts;\012all interior surfaces and mechanical structures are covered with anechoic wedges) provides a useable volume of 103 m3 (5.7 x 4.3 x 4.2 m3), a lower limiting frequency of 75 Hz, and background noise lower than 20 dB SPL (A Weighting). NC_GLOBAL.RoomLocation: IRCAM, Paris, Anechoic Room (Studio 7) NC_GLOBAL.ListenerShortName: 1068 NC_GLOBAL.ListenerDescription: Human subject with microphones positionned at the entrance of the blocked ear canal. NC_GLOBAL.SourceShortName: Three ELAC 301 NC_GLOBAL.SourceDescription: Three ELAC 301 loudspeakers mounted vertically NC_GLOBAL.ReceiverShortName: Knowles FG26107 C34 NC_GLOBAL.ReceiverDescription: For each subject individualized silicon ear molds were fabricated by a hearing aid specialist.\012They were cut to fit to the external auditory meatus, varnished for rigidification, and\012drilled to hold the Knowles FG26107 C34 miniature microphones and cable connectors.\012The microphones are connected to a custom made low-noise preamplifier and signal conditioner\012with a stabilized voltage regulated power supply to reduce total harmonic distortions.\012Audio signals are then transmitted to a RME Fireface 800 digital audio interface, which\012is also used for measurement signal playback. NC_GLOBAL.EmitterShortName: ELAC 301 NC_GLOBAL.EmitterDescription: Non-coaxial two-way ELAC 301 loudspeakers were used for the HRIR measurements.\012The distance between tweeter and woofer is approximately 6 cm; the cross-over frequency\012is 3.2 kHz. The tweeter-woofer distance corresponds to an elevation-angle bias of less than 2 deg.\012The loudspeakers are driven by a 4-channel Yamaha P2040 amplifier that delivers up to 20 watts into 8 ohms loads.
