Abstract: An earphone device is provided and includes: a wireless or wired transceiver module configured to receive a first electrical signal from an electronic device via a wireless or wired transmission network; a first compensation module connected to the wireless or wired transceiver module and arranged in a streaming audio gain compensating filter of an active noise cancellation chip, where the first compensation module is used to implement a frequency response curve to calculate a frequency response of the first electrical signal in each frequency band, and to generate a first filter parameter of a target frequency response curve via a first compensation gain conversion model, so that the first filter parameter gain compensates the first electrical signal in each of the frequencies; and a first transducer connected to the first compensation module to convert the first electrical signal gain compensating into sound and then transmit the sound.

Abstract: A self-fitting hearing compensation device with real-ear measurement is provided and includes: a first transducer, which receives a first test signal from a device and converts the first test signal into a first electrical signal; a first hearing compensation module, which is connected to the first transducer and performs gain compensation on the first electrical signal; a second transducer, which is connected to the first hearing compensation module, converts the gain-compensated first electrical signal into sound, and transmits the sound into an ear canal; and a third transducer, which synchronously converts the sound transmitted in the ear canal into a second electrical signal, so as to transmit the second electrical signal to the device via a wireless transmission network. In addition, a self-fitting hearing compensation method and a computer program product are also provided.

Abstract: A hearing compensation device is provided and includes a transducer, which receives sound to convert the sound into electrical signals; and a noise reduction module and a hearing compensation module, which are connected to the transducer to receive the electrical signals synchronously. The noise reduction module generates opposite signals with the same energy as the electrical signals to remove ambient noise. The hearing compensation module obtains a real-time customized audiogram or a hearing table according to a user's current real environment. Multiple sets of parameters of multiple filters are searched via active noise cancellation technology with optimization method and loss function to generate an optimal filter parameter value, such that the noise reduction module and the hearing compensation module disposed in the same chip perform real-time and/or synchronous processing to provide a hearing aid with reduced signal delay, real-time and user customization.
