fan-shaped.
For premium sound quality, most auditoriums are fan-shaped by design with angled floor and ceiling surfaces, and walls that are not parallel to one another.
Which is most optimum shape of a auditorium for good acoustics?
Shape of the Room
Generally, you want to avoid square rooms or narrow, rectangular rooms since the parallel walls can cause sound waves to bounce back and forth continuously creating undesirable reverberations that muddy the overall sound clarity.

By dropping the level of background noise, greater clarity to original sound is restored and premium sound quality produced.
Which is the most preferred wall for acoustically correct auditorium?
3) Shape: – Instead of parallel walls spade walls are preferred, curved surfaces should be built with proper care.
How do you soundproof an auditorium?
How to Soundproof an Auditorium. To reduce the echo between walls, the most common approach is to add sound absorbing acoustical panels. Most sound panels consist of fluffy, porous material that trap sound. Any area with large amounts of flat reflective space should receive treatment.
How big should an auditorium be?
Auditorium Dimensions & Layout
Dimensions can get tricky, but a good rule of thumb is arranging the size of the auditorium around the type of performance and the number of audience members you plan to seat: 200 seats: 270m? | 2,900 ft2. 150 seats: 190m? | 2,000 ft2. 75 seats: 125 m? | 1,350 ft2.
What is the slope of an auditorium?
In general the higher the APS the lower the seating rake is. The rise of each row of seating can be calculated using Eq. 17.3. In the orchestra-level seating a 1:9 rake for the first ten rows, and thereafter a 1:8 slope, yields a good result for a theater stage having a normal 42-inch (1.07 m) height.
What is the average size of a movie theater building?
The average for the full database was 3,800 square feet (353 square meters). We decided to lower that specification to 3,100 square feet (288 square meters) to include several GSCA member theaters that would otherwise have not qualified.
Why do auditoriums have high ceilings?
Acoustically, this means less distance between the stage and the audience; therefore, the reflective surfaces are closer. Sound in a compact space can be perceived as louder. By increasing the ceiling height to 15 m (50 ft), the room volume expanded and the level of sound decreased.
Is code for auditorium design?
IS 2526: Code of practice for acoustical design of auditoriums and conference halls.
Why do auditoriums sound different?
Much of the sound we hear in an auditorium is reflected sound.Hard surfaces such as a concrete floor, reflects all the sound. Softer surfaces such as a carpeted floor, absorbs the treble range of frequencies and reflects the bass range. Other surfaces work nearly in an opposite manner.

Which property of sound is not desirable while designing auditorium?
Explanation: The sound level and at dead spots is generally inadequate for satisfactory hearing. This defect can be remedied by the installation of the suitable diffuser so as to have even distribution of sound in the hall. 3.
How will you choose the reverberation time in small and big auditorium?
The optimum reverberation time for an auditorium or room of course depends upon its intended use. Around 2 seconds is desirable for a medium-sized, general purpose auditorium that is to be used for both speech and music. A classroom should be much shorter, less than a second.
What makes good acoustics?
For good acoustics in an auditorium, the sidewalls and ceiling should be carefully oriented and acoustically hard to reflect performance sound to the ears of the audience. These sound-reflective surfaces provide very important natural sound reinforcement for better hearing.
