METHOD FOR PREPARING AN AUDIOGRAM OF A TEST SUBJECT BY USE OF A HEARING INSTRUMENT
A method for preparing an audiogram of a test subject by use of a hearing instrument. A sound signal is recorded in an auditory canal of the test subject at least partially closed by the hearing instrument by a first electroacoustic input transducer of the hearing instrument. A first input signal is generated therefrom. A test sound is generated by an electroacoustic output transducer of the hearing instrument and output into the auditory canal of the test subject at least partially closed by the hearing instrument. A hearing threshold of the test subject at at least one test frequency is ascertained on a basis of a reaction of the test subject to the test sound and by use of the first input signal.

Audio profile for personalized audio enhancement
A system creates an audio profile. The audio profile may be stored in a database. For example, the audio profile may be securely stored in a database of a social network and associated with a user account. The audio profile may contain data describing the way in which the specific user hears and interprets sounds. Systems and applications which present sounds to the user may access the audio profile and modify the sounds presented to the user based on the data in the audio profile to enhance the audio experience for the user.
