摘要： A dynamic hearing protection method and device with which a hearing protection device specific differential head related transfer function corresponding to the difference between an open ear resonance measurement of the user's ear canal or an ear canal approximating the user's ear canal without the hearing protection device being worn in the ear canal and an open ear resonance measurement with the hearing protection device being worn in the ear canal as a function of the angle of sound incidence is determined and when using the hearing protection device, a frequency-dependent gain function to the captured audio signals selected according to the presently determined angle of sound incidence with each of the gain functions is determined by inverting the previously determined HPD specific differential HRTF for the respective sound incidence angle, to compensate for the effect of the presence of the hearing protection device on the open ear resonance.
