Abstract:
1. A method of processing a sound segment, used in a hearing aid, the method comprising: checking a type of the sound segment, wherein the type of the sound segment is selected from at least the following three types: a low-frequency type, a mixed-frequency type and a high-frequency type, wherein: if the sound segment is determined to be the high-frequency type, performing a first frequency lowering process on the sound segment, wherein the first frequency lowering process at least processes a portion of the sound segment with its frequency over B Hz, and the energy of the portion of the sound segment with its frequency over B Hz is not decreased before the first frequency lowering process is performed, where 2000≦B≦5000; and if the sound segment is determined to be the mixed-frequency type, performing a second frequency lowering process, wherein the second frequency lowering process at least processes a portion of the sound segment with its frequency over B Hz, and the energy of the portion of the sound segment with its frequency over B Hz is decreased before the second frequency lowering process is performed.
