The 777 does not reduce thrust to compensate for an engine failure. Among other things, this goes against common sense. During an engine failure, when there is a significant difference in thrust, the TAC (Thrust Assymetry Compensation) automatically applies sufficient rudder in the appropriate direction. The engine thrust will remain at the pre-programmed value unless the auto-throttle is disconnected and the thrust levers are physically moved. Once the aeroplane is at acceleration altitude and clean (gear & flaps up), the thrust will reduce to maximum continuous thrust (MCT) as the aeroplane climbs to the next altitude either in the FMC or the MCP altitude window.
The reduced cabin noise is likely to be due to half the original amount of bleed air being pumped through the air-con and half the engine noise!!
In the meantime, well done to the guys concerned. The outcome was never in doubt.
