The present invention discloses an audio device output energy control method for protecting hearing, the method including: step S1, obtaining energy or pressure at a speaker or at any point in a sound field from the speaker to a tympanic membrane by means of calculation or measurement, which serves as the energy or pressure at the tympanic membrane or cochlea of a user after compensation or calculation; step S2, calculating a cumulative hearing loss value according to the energy or pressure at the tympanic membrane or cochlea of the user, or calculating cumulative energy at any point in the sound field from the speaker to the tympanic membrane according to the energy or pressure at that location, and then equivalently calculating a cumulative hearing loss value at the tympanic membrane or cochlea of the user; step S3, comparing the cumulative hearing loss value with a preset hearing loss threshold, and performing step S4 if the cumulative hearing loss value reaches the hearing loss threshold; and step S4, reducing a volume of the audio device. The present invention can monitor the energy at the tympanic membrane or cochlea of the user in real time and adjust the output energy of the audio device in time, thus realizing hearing protection.
