Claim 18:
19. A method comprising:
causing, by a tone generator located within headphones, a. tone to be emitted by a speaker of the headphones;
detecting, by a microphone located within the headphones, the tone;
determining, by a sound pressure level (SPL) measurement element integrated into the headphones and coupled to the microphone, an SPL of the tone;
comparing the of the tone with an intended SPL for the tone, yielding a comparison result;
determining whether to adjust SPLs of subsequent tones to-be emitted by the speaker based on the comparison result; and
applying, by a compensation element within the headphones, compensation to sounds emitted by the speaker, the compensation based on the comparison of the SPL of the tone with the intended SPL for the tone,
wherein applying the compensation includes performing a reverse equalization, applying a gain to frequencies corresponding to hearing loss of a user, lowering frequencies other than the frequencies corresponding to the hearing loss of the user, and compression.
