Abstract(in English) | In this report, examination about the method of emphasizing the sound which the noise which the MRI equipment used for medical inspection etc. emits superimposed is performed. The noise of a very long cycle is included in the noise which MRI equipment emits, and the peculiar periodicity noise has barred the telephone call to a doctor from a patient. Then, ALE is used in order to oppress the periodicity noise. This is a system which sets only a periodicity ingredient as a prediction target by prefacing a delay element in an adaptation filter. Therefore, if this system is used, the periodicity ingredient of MRI equipment noise will be oppressed, and it is thought possible to emphasize a sound. Moreover, by this report, the cycle of the noise is detected automatically and the technique of performing noise oppression is also examined. |
