Focused Sound Technologyhot!
12/12/2008
Its safe to say that none of the focusing devices available today can create sound at only one spot and absolutely nothing elsewhere. All have a certain amount of spillover beyond the target area. This at first seems disappointing, but spillover can be beneficial because it gives a hint that the display actually carries a soundtrack... (download file to read more)

Many of the inquiries we receive are from facilities looking for a magic solution to a difficult audio problem. Usually they have already tried several types of speakers for the exhibits with unsatisfactory results. Rather than face the real problem, which is the acoustics of the space, they continue to look for the magic loudspeaker which will solve the problem...(download file to read more)
Evaluating Mini Arrayshot!

The distance to the focal point is set at the factory. Typically it is set for three feet from the center of the array. Set the listening level at the focal point. The purpose of the focused array is to concentrate the sound in a specific area. Set the level in the listening area, not outside of it...(download file to read more)
Evaluating Audio Arrayshot!

We receive comments on our demonstration arrays that range from fantastic to it doesn't work, I can hear it all over the room. It's best to evaluate the arrays in the application where they will be used. A small quiet office is quite different than an open noisy exhibit area... (download file to read more)

How Dakota Audio Speakers Work:If two or more sound waves arrive at the same place at the same time, they add and produce a sound wave that is the sum of all of the incoming sound waves.
When multiple sound waves arrive at random times, some waves cancel, producing a sound wave that is less than the sum of the incoming waves.
If several speakers are mounted equal distance from the listener, the sound from each of the speakers arrives at the listener's ears at the same time. The resulting sound is considerably louder than the sound from each individual speaker.
While it wouldn't be practical to mount the speakers in a spherical array, we can achieve the same results by delaying the launch time from the speakers. |
