Different from usual architectures, aircraft has a very long and slender room which is exposed to many varied levels of external noises, including internal noise sources.<BR>In such a case the interior noise is widely distributed even in the same room.<BR>Research for quantity of soundproof material to be necessary and the efficient way to put it on the walls in aircraft design necessitates practical and reliable method to estimate the interior noise level of aircraft.<BR>An approximate estimation scheme is proposed in this report.<BR>This method was applied to two practical examples and the result was satisfactorily well within 5 dB in comparison with test results.
