Hearing loss compensation apparatus including external microphone

A hearing loss compensation apparatus, comprising:

• a connection member operatively connected to a microphone and configured to transfer an audio signal received from the microphone;
• and
• a hearing aid compensation body configured to compensate the audio signal based on auditory characteristics of a user, and to output a compensated audio signal in a direction of an ear drum of the user, wherein the microphone is external to the hearing aid compensation body, and
• wherein the auditory characteristics of the user include a three-dimensional equal loudness contour of the patient which is determined by mapping hearing thresholds to corresponding directional angles and mapping frequencies to a two-dimensional plane constituted by a frequency and a directional angle.

A hearing aid body of a hearing aid compensation apparatus, comprising:

• a signal compensation unit configured to compensate an audio signal received from an external microphone and to amplify the audio signal for each frequency band based on auditory characteristics of a user;
• and
• a signal output unit configured to output the compensated audio signal,
• wherein the auditor characteristics of the user comprises a three-dimensional equal loudness contour of the user that is determined by mapping hearing thresholds to corresponding directional angles and by mapping frequencies to a two-dimensional plane constituted by a frequency and a directional angle.
