  • Patent number: 3974335
    Abstract: A system for testing the hearing of a patient by telephone is disclosed. The patient calls a number, either by touch tone or by dialing, whichever is available, that gives access to the testing equipment. The equipment gives the patient instructions as to how to proceed. The equipment, during the course of the test, applies discrete audio tones at various levels to the phone that the patient is holding to one ear, and records the tones and levels that the patient can hear. The process is repeated for the other ear and this is also recorded. A code number is also recorded so that the test results may be recovered. When the test is complete, the equipment tells the patient what the code number is and that upon payment of a fee the results of the test will be transmitted to him. The equipment may be used in a doctor's or personnel officer's office, in which case the equipment gives the code number, but does not mention a fee.
