The measurement module "Automatic Pure Tone Audiometry (APTA)" offers a procedure to automatically determine the hearing threshold at different frequencies without an experimenter. Pulsed sine signals are presented several times with an increasing level and the test person can respond via joystick or screen input (mouse, touch screen) as soon as the respective signal has been detected. A Hughson Westlake method is used for level control.
After several presentations of the same frequency, the hearing threshold is determined accurately and reproducibly.
The method has been validated in several publications. All audiometry headphones supported by the Oldenburg by the Oldenburg Measurement Applications can be used for the measurement.
