Which is most optimum shape of a auditorium for good acoustics?

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 is speaker placement calculated?

The easiest way to figure out the speaker placement is by marking the centerline on the wall opposite. This mark is exactly 180° from the center speaker and should be identical to the center speaker. Measure the distance from the rear wall, accounting for speaker depth, to the MLP.

How far should left and right speakers be from center?

about 3 to 4 feet
The front left and right speakers should be placed about 3 to 4 feet away on either side of the display screen or TV. They should face the viewers pointing towards the center of the room. It is recommended to place them at an equal distance from the center speaker (or the subwoofer in this case).

What height should speakers be?

The height speaker channels should be placed in the upper left/right corners of the front stage. Typically, this will be 40-45 degrees off-axis and about 8 feet in height. A downward tilt of the speaker will improve mid/high frequency response and reduce ceiling bounce reflections.

What are the criteria of a good Auditorium?

1) The initial sound should be of adequate intensity. 2) The sound should be evenly distributed throughout the hall. 3) The successive nodes should be clear & distinct. 4) Noise has to be taken care of.

What are the conditions for good acoustics of an Auditorium?

According to classic acoustics theory there are five requirements which, when met, result in good acoustics:

• an appropriate reverberation time.
• uniform sound distribution.
• an appropriate sound level.
• an appropriately low background noise.
• no echo or flutter echo.

Where should I place my left and right speakers?

Left and right speakers are angled 30 degrees each side of the sweet spot centerline and speakers acoustical centers projections joins at sweet spot position. A simple recommendation is to place the sweet spot behind the listener’s head, not just in front of his face.

Where should you not place speakers?

What not to do

• Don’t place stereo speakers too near the front wall (the wall behind the speakers).
• Don’t orient the speakers so that they’re completely parallel to each other.
• Don’t just set speakers directly on the floor unless they are floor-standing tower speakers.
• Don’t put anything in front of the speakers.

How far should speakers be from back wall?

2-3 feet
Speakers should be at least 2-3 feet away from the nearest wall (especially if your speaker is in a corner). Many speakers have rear-facing bass ports. Positioning a rear bass port too close to the wall will reflect sound waves, resulting in time smearing.

Where do I put my left and right speakers?

Left and Right are clearly marked on both packings and the rear of the loudspeakers. Place the Left and Right speakers to the left and right as seen from the listening position. “Music expresses that which cannot be said and on which it is impossible to be silent.”

Should speakers be angled?

Speaker angles Positioning the speakers at a 60-degree angle gives you the best ‘stereo image’ of these sounds. Dust off your old protractor and position the speakers 60 degrees apart. It can help to place a small marker at your listening position and work it out from there.

Where should stereo speakers be placed?

Speakers should be at least 2-3 feet away from the nearest wall (especially if your speaker is in a corner). Many speakers have rear-facing bass ports. Positioning a rear bass port too close to the wall will reflect sound waves, resulting in time smearing.

Where to place speakers in a rectangular room?

If you are forced to place your speakers on the long side of a symmetrical, rectangular room, create a Golden rectangle in each rear corner. Your speakers can then be placed anywhere along a line extending from the outside rear corner through the inside front corner (Diagram F).

How to position Your Speakers for Great Sound?

1 Initial placement. Decide roughly where you will be positioned when listening, then place your speakers so that they form an equilateral triangle with your listening position. 2 Speaker separation. 3 Speaker height. 4 Wall proximity. 5 Adjust speaker angle (toe-in). 6 Room arrangement. 7 Isolate your turntable.

How tall should my speakers be in relation to the wall?

Speaker height. Position your speakers so that the tweeters are at roughly the same height as your ears. (Tweeters are the small drivers on your speakers. They are responsible for handling the high-frequency treble range.) Wall proximity. Move your speakers at least 2-3 feet away from the nearest wall.

Where do you place your speakers on a shelf?

If your speaker is near the back of a shelf, sound will reflect from any and all surfaces in front of the cone. Remember that walls reflect sound, too. Speakers should be at least 2-3 feet away from the nearest wall (especially if your speaker is in a corner).
