Self-fitting hearing compensation device with real-ear measurement, self-fitting hearing compensation method thereof and computer program product

A self-fitting hearing compensation device with real-ear measurement, comprising:

• a first transducer configured to receive a first test signal from a device and convert the first test signal into a first electrical signal;
• a first hearing compensation module connected to the first transducer and configured to perform gain compensation on the first electrical signal;
• a second transducer connected to the first hearing compensation module, wherein the second transducer converts the gain-compensated first electrical signal into sound and transmits the sound into an ear canal;
• and
• a third transducer configured to synchronously convert the sound transmitted in the ear canal into a second electrical signal, wherein the third transducer transmits the second electrical signal to the device via a wireless transmission network,
• wherein the device calculates an energy distribution of the second electrical signal in each frequency band, and compares an error between the energy distribution and a target gain and a hearing threshold via a second hearing compensation module, wherein if the error does not meet an error target, the device quantizes the error to generate corrected filter parameters via a compensation gain conversion model, and the corrected filter parameters are transmitted to the first hearing compensation module via the wireless transmission network to perform hearing gain compensation.
