This invention relates to a method and device for conducting a pure tone audiometry using tones of different frequency and intensity utilizing an adaptive procedure. Tone signals with at least two different frequencies are being independently changed by delivering to test person a set of at least three different test stimuli those test stimuli being selected from a group of no tone at all one long tone with a first frequency and a multitude preferably three short tones of a second frequency said second frequency being higher than the first frequency receiving the test persons response said response corresponding to one of the different test stimuli. A next test stimulus is presented to the test person and is selected according to the correctness of the test persons last response.
