A method of manufacturing a component (110), the method comprising the steps of: providing a component having a first portion (20, 40, 60, 80, 100, 116), which first portion defines a cavity (26, 46, 66, 86, 106), characterised by; identifying a first frequency response of the first portion and / or the entire component, and introducing material (28, 48, 68, 88, 108) into the cavity to achieve an adjusted frequency response of the first portion and hence a desired frequency response of the component. |
