In the paper the influence of shape on the acoustic field inside enclosure without damping is presented. Two-dimensional shapes: rectangular, rectangular with one inclined side, regular triangle, regular pentagon and regular hexagon were investigated. Irregularity of acoustic pressure in enclosure is evaluated in terms of mean value and standard deviation, whereas frequency distribution is evaluated in terms of Bolt criterion. Shape has a strong influence on the irregularity of acoustic pressure and frequency distribution of the normal modes in enclosure. Regular triangle, pentagon and hexagon shapes show lower mean value of acoustic pressure and worse irregularity of acoustic pressure and frequency distribution as compare to rectangular one. Inclining one side in rectangular shape up to 10° does not affect on the irregularity of acoustic pressure whereas improves frequency distribution of the normal modes. Father inclining is not favorable
