Electronic hearing device and method

A method performed by a hearing system having a hearing device, the hearing device comprising an acoustic output transducer, a first acoustic input transducer, a second acoustic input transducer, a first wireless communications unit, and a processing unit, the method comprising:

• emitting an otoacoustic stimulation signal via the acoustic output transducer of the hearing device;
• obtaining a first acoustic signal by the second acoustic input transducer of the hearing device;
• emitting another otoacoustic stimulation signal via the acoustic output transducer of the hearing device;
• obtaining a second acoustic signal by the second acoustic input transducer of the hearing device;
• determining whether a first criterion is satisfied based on the second acoustic signal;
• determining a deviation value based on the first acoustic signal and the second acoustic signal if the first criterion is satisfied based on the second acoustic signal;
• and
• in accordance with the deviation value satisfying a second criterion, providing a notification signal, the second criterion being different from the first criterion.
