Abstract
An enhancement equalizer (EEQ) can be configured to compensate for hearing loss. An app or application can assist a user with measuring hearing loss at various frequencies (e.g., threshold sensitivity versus normal hearing). Using these measurements, the system may compute a set of filters for an EEQ that can boost different frequencies by different amounts corresponding to the user's sensitivity to that frequency. The measurement and resulting EEQ may be earphone specific (e.g., both the measurement and the filter computation may depend on the particular type/model of earphone used). In some implementations, the system may allow the user to select correction strength that controls an amount of correction applied (e.g., 25%, 50%, or 75% of full correction). In some implementations, the system may adjust the EEQ and/or correction strength according to the volume of playback (e.g., by applying less correction at higher playback volumes to avoid triggering earphone limiters).
