The sound intensity level inside a typical modern airliner inflight is 66.0 dB. The air in the cabin has density 0.920 kg/m3 (less thanin the atmosphere at sea level) and speed of sound 344 m/s. (a) What isthe pressure amplitude of this sound? (b) If the pressure amplitude wereincreased by a factor of 10.0, what would the new sound intensity level be?
