A method of determining the pitch of a patient's tinnitus tone, the method comprising the steps: presenting a first test tone to the patient varying within a predetermined first frequency range or around a predetermined first intensity range a frequency or an intensity of the test tone by the patient to approximate the first test tone to the patient's tinnitus tone, thus providing a tinnitus tone; defining a second frequency range and a second intensity range around the preliminary estimate of the patient's tinnitus tone; determining a final estimate of the patient's tinnitus tone by allowing the patient to listen to and vary frequency and intensity of a second test tone within the second frequency range and the second intensity range to approximate the second test tone to the patient's tinnitus tone, wherein the method is implemented on a digital processing unit of a device, in particular a handheld, the device comprising an output unit for delivering the test tones to the patient; and a user interface for variation of the frequency and the intensity of the test tones by the patient, characterized in that the user interface comprises a touch screen defining a two-dimensional plane, which is configured so that sliding in a first dimension leads to an increase or decrease of the frequency and sliding in a second dimension leads to an increase or decrease of the intensity, wherein the frequency and the intensity can be simultaneously varied by moving a patient's finger on the two-dimensional plane in the first and second dimensions, and wherein the second frequency range and the second intensity range extend non-symmetrically from the frequency and intensity of the preliminary estimate. presenting a first test tone to the patient varying within a predetermined first frequency range or around a predetermined first intensity range a frequency or an intensity of the test tone by the patient to approximate the first test tone to the patient's tinnitus tone, thus providing a tinnitus tone; defining a second frequency range and a second intensity range around the preliminary estimate of the patient's tinnitus tone; determining a final estimate of the patient's tinnitus tone by allowing the patient to listen to and vary frequency and intensity of a second test tone within the second frequency range and the second intensity range to approximate the second test tone to the patient's tinnitus tone, wherein the method is implemented on a digital processing unit of a device, in particular a handheld, the device comprising an output unit for delivering the test tones to the patient; and a user interface for variation of the frequency and the intensity of the test tones by the patient, characterized in that the user interface comprises a touch screen defining a two-dimensional plane, which is configured so that sliding in a first dimension leads to an increase or decrease of the frequency and sliding in a second dimension leads to an increase or decrease of the intensity, wherein the frequency and the intensity can be simultaneously varied by moving a patient's finger on the two-dimensional plane in the first and second dimensions, and wherein the second frequency range and the second intensity range extend non-symmetrically from the frequency and intensity of the preliminary estimate. <EOS>
