<p>This invention relates to a method for conducting a pure tone audiometry, using tones of different frequency and intensity utilizing an adaptive procedure, characterized in that 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, presenting a next test stimulus to the test person after a short delay, preferably half a second to a second after the test persons response, the next test stimulus of that frequency having a lower intensity in case the answer of the test person was correct and the test stimulus did include a tone at all, and having a higher intensity in case the answer was not correct, whereas the next test stimulus being delivered to the test person, following an answer, may utilize a different frequency, such further improving the accuracy of the test result. It also relates to a device for conducting an automated pure tone audiometry screening, comprising a tone generator, being capable of delivering pure tones of different frequencies and intensities as well as being able to deliver tones either as a long tone or a set of shorter tones, also comprising a set of at least three response buttons and an electronic device, being able to conduct a method as described.</p> |
