What is it indicated for?
The CCA-200 Computer Controlled Audiometer is an air conduction audiometer designed to provide automatic hearing testing. A series of tones is presented by the CCA-200 through a TDH-39 headset to the test subject. The test subject then presses a hand switch to indicate to the CCA-200 that the tone has been heard. The CCA-200 proceeds with the hearing test using the Modified Hughson-Westlake method of hearing testing, and records the subject's responses.…

The CCA-200 Computer Controlled Audiometer is an air conduction audiometer designed to provide automatic hearing testing. A series of tones is presented by the CCA-200 through a TDH-39 headset to the test subject. The test subject then presses a hand switch to indicate to the CCA-200 that the tone has been heard. The CCA-200 proceeds with the hearing test using the Modified Hughson-Westlake method of hearing testing, and records the subject's responses. The resultant data are available to print on an external printer connected to the control computer or to store in the computer.
The CCA-200 can perform its function only on command from a control computer. The computer monitor displays the setup and control screens that are used to perform the test functions. An IBM compatible computer with a 486DX2-50 or processor, running Windows 95 or Windows NT, is required. Control of the CCA-200 is handled through the RS232 serial port. The computer is not included with the CCA-200.
The CCA-200 is designed for use in test environments where multiple automatic hearing tests are controlled from a single computer. The CCA-200 has a range of options for both computer interfacing and automatic testing, such as multilingual voice instructions. These options are selected using a setup screen on the computer.
