Speech audiometer was used in detecting a high degree loss of hearing among the candi-dates of college-entrance examination. Word-sounds were produced at 40db in strength. Persons who failed in this test by loss of hearing or numerous errors in the response were tested separately with better test faci-lities. The time required for testing each in-dividual was from 42 to 48 seconds.
