摘要：
Using a method of continuous adjustment to obtain a response curve indicative of the users perception of the variations in an adaptive parameter stimulus, the methods being directed to maximize regularity of user interactions around the response curve. The methods find particular application in audiometric tests, including when carried out using unreferenced or non-calibrated audio-systems, in embodiments this is psychometric tuning curve testing, but also have more general application and may also be used for similar test applications in other fields. An adaptive parameter is continuously adjusted and the rate of change of the adaptive parameter is adjusted depending on the regularity of user interactions. The adjustments are directed towards neutral user interaction around the response curve and providing more uniform intervals between successive user interactions. The stimulus may be an audio stimulus with the adaptive parameter being amplitude and the second variable parameter, frequency. Further embodiments may utilize a masking signal with a variable frequency sweep.
