The Echo-Screen closes the gap between audiological diagnostics, which is time consuming and expensive and the standard pediatric method of screening by behavioral observation. Since this screening device is not dependant on an expert operator, it is possible to effectively select children whose hearing may require further investigation by a hearing professional.
The Echo-Screen is a screening device based on the principle of measuring Transiently Evoked Otoacoustic Emissions (TEOAE). The unit is not larger than a pocket calculator and it can be operated immediately without the need for prior audiological expertise. Once the probe has been inserted into the child's auditory canal ann the the device has been switched on by pressing a button, the measurement test runs automatically.The results are also evaluated automatically by a microprocessor. If a significant emission can be measured in accordance with a strict signal-statistical criterion, the measurement is terminated with the result PS (PASS).
This often takes only a few seconds. It is thus possible, with a high degree of certainty, to rule out the presence of a hearing disorder that might affect the ability to acquire speech skills when there is a threshold elevation of more than 30 dB. When the measurement is being performed, the operator can read off the stage reached in the signal-statistical evaluation by means of a LC display. This is a pre-owned instrument with some sign of use but I believe it is working fine. I was able to charge both batteries and run several tests.
This device automatically calibrates itself before each test. I did not have an infant to actually test the device on but I did run several tests on myself and the machine worked without issue.
