Problems solved by technology

[0004] However, such self-test methods and systems penalize the patient for being hard to hear, because the better the patient listens, the more the patient is rewarded and the sooner
There is therefore an incentive for the patient to claim to hear a sound when in fact he or she did not, making the test less accurate
Also, the patient has to concentrate the entire time, which can be stressful and can lead to inaccurate results

Embodiment Construction

[0028] figure 1 The principle of the invention is schematically illustrated by means of a flowchart.

[0029] In step 10 a first test is performed by the patient. For example, the first test in its simplest form involves the patient adjusting the sound pressure level of an audio stimulus, such as a pure tone or a pure tone presented with masking noise, until the hearing threshold (HL), comfort loudness level (MCL), or uncomfortable Loudness Level (UCL). The patient then selects this sound pressure level.

[0030] Subsequently, in step 11, a second test is performed by the patient in which the same audio stimulus is presented and the same sound pressure level is adjusted and selected in the same way.

[0031] It is advantageous that the patient does not receive any indication of the selected absolute value when performing the first test and the second test, as this may bias the test results.

[0032] Subsequently, in step 12 the value of the sound pressure level selected by...

Abstract

A self-administered hearing testing comprises carrying out a first and second test comprising adjustment by the patient of the sound pressure level of at least one audio stimulus to the same specified hearing perception level and selection of the corresponding sound pressure level, thereby generating a first and a second test result corresponding to the values of the sound pressure levels selected by the patient; comparing the first test result and the second test result. The result of the test is accepted or rejected based on the closeness of the test results, and feedback is provided to the patient based on this closeness. In consequence, since feedback is given based on closeness of results of the two tests rather than the level at which the patient hears the audio stimulus, the test gives more accurate results than tests based on providing feedback according to absolute hearing ability.

Description

technical field [0001] The present invention relates to measuring the auditory response of a patient. Such measurements are typically performed to determine hearing response and hearing loss, to identify candidates for hearing aids, and to adapt hearing aids to a particular patient's hearing loss. By "hearing aid" is understood a conventional hearing aid of the behind-the-ear or in-the-ear type, and also a cochlear implant for directly stimulating the auditory nerve. Background technique [0002] Traditionally, a patient's hearing response is measured by an audiologist by presenting the patient with a series of audio stimuli, which the patient then responds to as he or she hears the stimuli. The stimuli are typically pure tones at various loudness levels and / or at different frequencies, and may be presented along with masking noise. This is a labor-intensive process and is subject to error from eg the patient being able to see the audiologist initiate the stimulus or provi...
