title: Free-field tests of hearing-impaired listeners: early results.
abstract: Results are reported from a series of free-field tests of five hearing-impaired listeners. The tests provide relatively crude estimates of listeners' abilities in three types of experiments: free-field masked detection, source angle discrimination (both horizontal and vertical), and identification of source direction. Relations between abilities in the various tasks are noted.
