In the measurement of sound absorption coefficient in random incidence and determination of sound power levels of noise sources, the reverberation room is used very extensively.
In this paper, room sound field theory as the basis of measurement based on reverberation chamber and waveguide theory as the basis of measurement based on impedance tube are introduced.

We get and analysis the data of the reverberation, noise and acoustic pressure level of the Conference Hall and Lecture Hall in some northern university in measurement.
