The invention relates to a method for measuring noises in a cabin of a manned spacecraft. The method comprises: step a, on the basis of the space usage functions in the sealed cabin of a manned spacecraft, the inner area of the sealed cabin is divided into a working area and a living are; step b, the working area is divided into working sub-areas and sound sensors are arranged in the working sub-areas at equal intervals; step c, in the living area, living area sound sensors are arranged at intervals larger than intervals between the sound sensors in the working area; step d, vibration sensorsare arranged in the working compartment and the living compartment; step e, signals collected by the sound sensors and the vibration sensors are transmitted to a multi-channel measuring instrument arranged outside the sealed cabin of the manned spacecraft respectively; and step f, according to the signals collected by the sound sensors and the vibration sensors, noise distribution in all wavelength ranges in the working and living compartments of the manned spacecraft is determined.
