Sound signal compensation apparatus and method thereof

A sound signal compensation method executed in a sound signal compensation apparatus, comprising:

• receiving, by an input module, identification information identifying a first frequency with regard to a resonance of an ear closed by an earphone or headphone;
• and
• performing, by a compensation module, first compensation emphasizing a second frequency on a sound signal, the second frequency being determined based on the identification information or the first frequency as a frequency with regard to a resonance of the ear opened when the earphone or headphone is removed from the ear, wherein
• the performing performs the first compensation emphasizing the second frequency, at which emphasis is greater than or equal to 2 dB and less than or equal to 12 dB.

A sound signal compensation apparatus comprising:

• an input module configured to receive identification information identifying a first frequency with regard to a resonance of an ear closed by an earphone or headphone;
• a compensation module configured to perform first compensation emphasizing a second frequency on a sound signal, the second frequency being determined based on the identification information or the first frequency;
• and
• an output module configured to output the compensated sound signal, wherein
• the compensation module is configured to perform the first compensation emphasizing the second frequency, at which emphasis is greater than or equal to 2 dB and less than or equal to 12 dB as well as at which the emphasis is greater than or equal to 0.2 times the first frequency and less than or equal to 0.6 times the first frequency.
