	The auditory sphere lab, located in the Huygens basement (at A -2), contains more than 100 high-quality speakers that are mounted on an acoustically transparent wire frame, allowing us to present a sound source at many different locations around the subject. In the middle of the sphere is a chair where a person (the subject) can sit, so that his/her head is exactly in the center of the sphere. Each speaker also has a small LED, which can provide a well-defined visual stimulus. We measure eye-head orienting responses of subjects to study sound-localization performance to well-designed acoustic stimuli, as well as audio-visual spatial behavior under a variety of spatial-temporal disparities. The lab is equipped with a high-end binocular eye tracker system (EyeSeeCam), with which eye movements can be recorded at 500 Hz sampling rate per eye.

In the middle of the sphere is a chair where a person (the subject) can sit, so that his/her head is exactly in the center of the sphere. Each speaker also has a small LED, which can provide a well-defined visual stimulus. We measure eye-head orienting responses of subjects to study sound-localization performance to well-designed acoustic stimuli, as well as audio-visual spatial behavior under a variety of spatial-temporal disparities. The lab is equipped with a high-end binocular eye tracker system (EyeSeeCam), with which eye movements can be recorded at 500 Hz sampling rate per eye.

	The Sphere setup is a sound boot with about 130 speakers arranged in a sphere. ~~In the middle of the sphere is a chair where a person (the subject) can sit, so that his/her head is exactly in the centre of the sphere.~~ The subject can be presented with stimuli in the form of sounds or led flashes. The head movements of the subject can be tracked. The subject can also respond to stimuli by pressing a button. The experiments are controlled by a computer and electronics from outside the boot.		For whom?

			The equipment can also be used to test auditory spatial perception of patients with an implant, such as a cochlear implant, hearing aid devices, or a bone conduction stimulator. Companies producing such implants could gain more insight into the manner in which their products steer brain activity and perception. Audiological centers can use this technique for the same reasons.

	The lab is located at the underground corridor (floor -2) between the Huygens Building and the Goudsmitpaviljoen (NMR).		The lab is located at the underground corridor (floor -2) between the Huygens Building and the Goudsmitpaviljoen (NMR).
