PROBLEM TO BE SOLVED: To provide a hearing aid and a hearing aid processing system with which a change in the sound quality and a difference of a wearing feeling can be reduced when an earplug is changed by correcting a frequency characteristic changed depending on kinds of earplugs through filter processing of an integrated circuit. SOLUTION: A nonvolatile memory built in the integrated circuit 2 of a hearing aid main body 10 stores information associated with frequency characteristics measured in advance as to each of the prepared earplugs 5 to 7 of a plurality of kinds and earplug selection information for specifying the kind of the earplug selected from the earplugs of the plural kinds and fitted to the hearing aid main body. The integrated circuit 2 reads, from nonvolatile memory, the information associated with the frequency characteristic of the particular earplug according to the earplug selection information read from the nonvolatile memory and executes the filter processing on the basis of the read information to correct the frequency characteristic of the hearing aid different depending on kinds of the earplug.
