Description

Method for creating an audiogram of a person under test by means of a hearing instrument The present application is a divisional application of the original application of application number 202210948865.5, application number 2022, application number 08, application number 09, application name "method for creating audiogram of a person under test by means of a hearing instrument". Technical Field The invention relates to a method for creating an audiogram of a person under test by means of a hearing instrument, wherein test sounds are generated by an electroacoustic transducer of the hearing instrument and output into an auditory canal of the person under test, which auditory canal is at least partially closed by the hearing instrument, and wherein the threshold of the person under test is determined on the basis of the response of the person under test to the test sounds at least at one test frequency. The invention also relates to a hearing instrument with which the hearing threshold of a person under test at least one test frequency can be determined. Background A hearing instrument generally comprises any device which is arranged and designed for generating a corresponding output sound from an electrical output signal by means of an electroacoustic output transducer and for feeding the output sound to the auditory organ of the user. In particular, a loudspeaker, but in particular also a thermo-acoustic transducer or a bone conduction earpiece, can be used as such an output transducer. In this case, the hearing instrument can on the one hand be designed solely for producing output sounds from audio data, i.e. for example in the form of wireless, in particular earplug-shaped headphones. In this case, the output sound is generated from audio data, which may be given by music, for example, and which has been stored in advance or also transmitted to the hearing instrument (via a stream) via a corresponding antenna. However, the hearing instrument may also be present as a hearing aid which is provided for correcting or at least partially compensating for a hearing impairment of the user in that, for example, ambient sound is converted by means of at least one electroacoustic input transducer into a corresponding electrical input signal which is processed in the hearing aid according to the hearing requirements of the user and amplified here, in particular band by band, so that the processed input signal is fed as output sound to the auditory organ of the user via the electroacoustic output transducer. In particular for said correction of the hearing impairment of the user in the case of hearing aids (in the "narrow sense"), an audiogram of the user is usually generated. For each test frequency, which preferably covers the entire acoustic spectrum of the human auditory sensation, the audiogram gives the corresponding hearing threshold of the user at the relevant frequency, so that the hearing ability of the user can be compared, in particular with that of a person with normal hearing, in order to draw conclusions for the above-mentioned personalized signal processing in the hearing aid. However, in order to adapt the hearing instrument (in a "broader sense") to the user to improve the sound perception, i.e. for example to better acoustic performance in a specific frequency range, it may be advantageous to create an audiogram. In this case, the measurement of the hearing threshold at the individual test frequencies is usually carried out at the audiologist or the licensed acoustician, wherein test probes with sound generators are often introduced into the auditory canal of the user. Each test tone at the corresponding test frequency is generated at a continuously increasing or decreasing sound level, respectively, so that the user can give an identification of when he has heard the test tone at one test frequency or no longer heard it. A disadvantage here is that such a measurement of audiogram is performed by or by audiologists/acousticians. Disclosure of Invention The object of the present invention is therefore to provide a method by means of which an audiogram of a wearer of a hearing instrument can be established in as simple a manner as possible, yet reliably and as independent of the situation as possible, by means of the hearing instrument. The problem underlying the present invention is to provide a hearing instrument that is designed to create an audiogram of a wearer as simply and reliably as possible. According to the invention, the first mentioned technical problem is solved by a method for creating an audiogram of a person under test by means of a hearing instrument, wherein a first electroacoustic transducer of the hearing instrument receives a sound signal in an auditory canal of the person under test, which auditory canal is at least partially closed by the hearing instrument, and a first input signal is generated therefrom, wherein a test sound is generated by an electroacoustic transducer of
