What Makes A Good Auditorium?

an appropriate reverberation time. uniform sound distribution. an appropriate sound level. an appropriately low background noise.

What are the characteristics of a good auditorium?

Welcome back.

• The initial sound should be of adequate intensity.
• The sound should be evenly distributed throughout the hall.
• The successive nodes should be clear & distinct.
• Noise has to be taken care of.
• The size & the shape of the ball has also to be taken care.

What is the best shape for an auditorium?

fan-shaped
There are certain rules of thumb when designing a new auditorium. 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.

What are the acoustic conditions of a good auditorium?

Acoustic requirements of a good auditorium:-
The sound should spread everywhere inside the hall evenly and should be audible enough everywhere. The sound notes should be clear and distortions should be minimum. Undesired noise interfere with the sound from the source should be minimized.

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.

How do you design an auditorium?

7 Basic Rules for Designing a Good Theater

1. Design a functioning Auditorium according to the type of performance and the number of the audience.
2. Keep the standard distance for a comfortable audience seating.
3. The stage is important: choose wisely.
4. Keep the scenery low for better visibility.

What are the factors that should be considered in lighting an auditorium?

Auditorium Lighting

• Choose your focal point. Most auditoriums are set up so that the audience looks at a stage, pulpit, or podium of some sort.
• Consider placement.
• Have three zones of lighting.
• Don’t skimp on brightness.
• Focus on artificial light more than natural light.

What material absorbs sound best?

In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most.

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.

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.

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.

What is good acoustic design?

Good acoustic design requires knowledge of the physics of sound, the engineering qualities of materials, and the unique attributes of music and then applying this knowledge to building construction to create a facility that allows listeners to have an outstanding aural experience.

What building has the best acoustics?

6 of the World’s Best Sounding Concert Halls and the Science behind Their Architectural Acoustics

• The Perfect Acoustics.
• Philharmonie de Paris, France.
• Opera City Concert Hall, Tokyo.
• Musikverein, Vienna.
• Concertgebouw, Amsterdam.
• Boston Symphony Hall, Boston.
• Elbphilharmonie Hamburg, Germany.

What ceiling material is used for auditorium?

Wood ceilings in auditoriums, theatres and conference centres are key elements in room acoustics. The wood ceilings of these buildings are really wood acoustic ceilings made with acoustic panels made withsound-absorbent wood that control reverberation inside rooms.

What are school auditoriums used for?

It is used for all types of formal assembly: lectures, award ceremonies, dramatic plays, musical theatre productions, concert performances of orchestra, band, chorus, jazz band, battles of the bands, dance competitions and so on. These varied events place a range of demands on the room.

How do acoustics affect sound quality?

Acoustics: an integral part of the reproduction system
The ‘critical distance’, measured from the speaker, is reached when the reverberant sound level equals the direct sound level.Going beyond the critical distance means reducing the direct to reverberant ratio, thus the quality of the sound deteriorates even more.

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.

How tall should an auditorium be?

Auditorium Stage
Assume that the typical stage is 30-35 feet deep with a proscenium opening of 40-50 feet wide, and up to 30 feet tall. The side stage should be at least half the size of the proscenium opening on each side.

What is the average size of a theater stage?

Stage Depth 32 feet from back of curved proscenium. E. Wing Space 28 feet wide, 22 feet high.

Does Auditorium need natural light?

Focus more on artificial light: In addition to the above, it is vital that the focus is more on artificial light as compared to natural light. Although most locations require the incorporation of both types of lighting, auditoriums need to maintain low lighting levels to make the projected screens more visible.

What is value of illumination for auditorium?

An illuminance level of 500 lux is therefore recommended. At the same time, the lighting must be dimmed down during videos or screen based presentations. To avoid glare during lectures is necessary and the glare rating should not be above 19.
