This patent application discloses an apparatus and method for detecting acoustic signals originating in a brain, such as those that characterize intersaccular aneurysms. The apparatus has a piezoelectric detector mounted with a cupping receptacle, the receptacle formed to receive an acoustic matching medium and press the medium against the eye socket of a patient. In this manner, the apparatus provides an acoustic path between the brain and the detector that is inherently low loss and acoustically matched, making for a system that is inherently sensitive. In particular embodiments, the cupping structure can be goggles which can be mounted on the patients head for convenience, or can be of a form enabling a technician to press the structure against the eye socket. jhd
