In arrays of coupled oscillators, intrinsic localized modes are energy localizations, which are caused by nonlinearity and discreteness. Here, the considered array of coupled oscillators is subjected to a combination of sinusoidal excitation and noise excitation. Experimental studies with an array of coupled cantilever oscillators and numerical studies with a corresponding oscillator array model are conducted to examine spatially symmetric localizations. The effects of noise on these symmetric intrinsic localized modes are studied, by varying the sinusoidal excitation frequency, sinusoidal excitation amplitude, and noise intensity. It is demonstrated that in certain parameter ranges, the intrinsic localized modes can be created as well as destroyed by utilizing noise.
