connecting the devices to a programming computer after counseling the patient on the hearing devices;

measuring a real ear unaided response (REUR) after connecting the devices to the programming computer;

fitting the hearing devices with the closed molds to each ear of the patient after measuring the REUR comprising:

positioning each hearing device so that the earmold of the hearing device is inserted into one of the patient's ears wherein one ear is a test ear and the other ear is a non-test ear;

estimating a verification noise floor after positioning each hearing device in each of the patient's ears;

measuring real ear occluded response (REOR) by muting the sound generator, amplifier and microphones and administering a broadband or white noise from verification system speakers in the test ear after estimating the verification noise floor;

measuring real ear aided response (REAR) after measuring the REOR;

adjusting a gain-frequency response so that the REAR matches the REUR curve to achieve unity gain and result in real-ear insertion gain (REIG) that is 0 dB across frequency after measuring REAR;

adjusting loudness compression thresholds based on a patient's frequency-specific loudness discomfort levels after adjusting the gain-frequency response; and

repeating above steps for the other device in the non-test ear;

fitting the sound generator to the patient by configuring the sound generator to a set level corresponding to a patient-specific soft loudness judgement after fitting the hearing devices comprising:

inserting the one hearing device into each of the test and non-test ears of the patient;

activating the sound generator of the hearing device in the test ear of the patient to emit a low-level broadband noise after inserting the hearing device;

establishing a level with the patient where the noise is perceived to be comfortable but soft according to the Contour Loudness Test Category 3 after activating the sound generator;

varying loudness of the noise and obtaining categorical loudness judgments on the noise from the patient after establishing the level where the noise is comfortable but soft;

measuring real-ear sound generator (RESG) level to quantify SG output after varying the loudness of the noise and obtaining the categorical loudness judgments from the patient;

repeating above steps for the hearing device in the non-test ear; and

balancing both devices after the above steps are conducted on both the test and non-test ears of the patient; and

systematically increasing the loudness compression thresholds in subsequent sessions with an audiologist to transition the patient to normal hearing.

6. The method of claim 5 , further comprising administering audiometric testing to the patient prior to providing the hearing device to the patient.

7. The method of claim 5 , further comprising muting the receiver and amplifier and the at least one microphone of both hearing devices with the sound generator off prior to inserting the hearing devices into the patient's ears.

8. The method of claim 5 , wherein the sound generator is calibrated after estimating the noise floor by unmuting the sound generator and administering a white noise stimulus in the test ear.

9. The method of claim 5 , further comprising comparing data from REOR, REUR and noise floor to reference data in the fitting software prior to the fitting the sound generator.

10. The method of claim 5 , wherein the REAR is measured by the steps comprising:

muting the sound generator;

unmuting the receiver and amplifier and microphones after muting the sound generator;

administering a broadband or white noise stimulus to the test ear after unmuting the receiver;

having the patient categorize loudness of the stimulus after administering the broadband or white noise; and

subsequently increasing a frequency of the stimulus at intervals until the patient reports loudness category 6 categorical judgment.

11. The method of claim 5 , wherein the patient wears both devices for at least 8 hours per waking day.

12. The method of claim 5 , wherein the open earmold is swapped for the closed mold and is worn by the patient when in a controlled sound environment where no unexpected sounds are present.

13. The method of claim 5 , wherein all measurement stimuli are emitted at frequencies above the noise floor.

14. The method of claim 5 , wherein the both devices are balanced by activating the both devices simultaneously and adjusting each device to have equal loudness.
