Systems, devices and methods for fitting hearing assistance devices

A hearing assistance device fitting system comprising:

• a hearing assistance device comprising
• a control circuit;
• a microphone in electrical communication with the control circuit;
• an electroacoustic transducer for generating sound in electrical communication with the control circuit;
• a power supply circuit in electrical communication with the control circuit;
• and
• an external device in wireless communication with the hearing assistance device;
• wherein the system is configured to
• provide an audio sample to a hearing assistance device wearer;
• determine a degree of hearing impairment of the hearing assistance device wearer;
• compare the determined degree of hearing impairment to a threshold level of impairment;
• prevent the hearing assistance device wearer from continuing a device fitting process if the determined degree of hearing impairment is greater than the threshold level of impairment;
• receive input from the hearing assistance device wearer;
• receive input from the hearing assistance device wearer regarding a bass/treble balance;
• and
• determine a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL).
