High speed RTO's are hazardous, the suggestion above to stop just because you heard a BANG is ridiculous. Unless the noise of unknown origin is accompanied by unequivocal evidence of an engine failure leading to significant loss of thrust, engine fire, uninhibited Master Warning or Master Caution (above whatever your Company's SOP speed is) the take off is recommended to be continued. A stop with tyre damage approaching V1 is a gamble because retardation is degraded by this type of failure resulting in an unquantifiable increase in accelerate/stop distance....which may be in excess of that available.
