Sweet spot (sports)

The term sweet spot sweet spot sweet area or a type is called effective zone. If there is something in the sweet spot, it has or does it get the optimum effect.

The term comes from English and means " sweet spot ". Similarly as in German, the word is used here in the broad sense sweet, so as a loving or friendly. A possible free translation is optimal for point ideal point or optimum range.

Music

In the Hi-Fi range, it is the optimum listening position, the listening position at the so-called stereo triangle, an equilateral triangle, which is always displayed in the two-dimensional images as upside-down triangle. The tip is below the optimum listening position and the overhead peaks represent the position of the speakers. By adhering to this "sweet spot", so there should have the best stereo effect, the music being heard. Depending on the design and quality of the speakers in this sweet spot can be moved away from them even closer to the speakers or farther. This helps to experiment with his own equipment in order to achieve the optimum.

In the home theater area still hold the side or side - rear mounted effect speakers (rear speakers ) to appear in the calculation. Since Dolby Digital 6.1 and 7.1 complemented the whole thing with one or two rear center speakers. If you want here achieve the optimum theater effect, you have to sit in the sweet spot. This is achieved in addition to the stereo triangle by reasonable arrangement of the rear speakers to the seat or concurrent modification of the latter. Furthermore, it must, of course, the whole setup can be configured via the AV receiver, so not the case arises that some speakers too loud and others are too quiet. As a rule can be set to the listening position and also the volume level to be adjusted individually for each speaker in order to avoid run-time differences the distance.

The sweet spot is called in an audio system the spatial region in which the sound playback reaches the desired optimum sound. In a single reproduction varies, for example, with the distance to the speakers, the volume and the frequency spectrum of the sound.

For a stereo sound system, however, when listening to the same distance from both speakers is important so that the spatial position of the sound sources is again properly experienced. In addition, the sound should come " concert -like" from the front ( the theoretical stage ). The stereo sweet spot is quite small, it is in accordance with a rule of thumb on the third point of an equilateral triangle whose other points are the speakers.

When surround sound (multi -channel systems, such as five-or seven -channel surround sound in cinema), the size of the sentient Playback sweet spots on the type of recording and the intelligent mixing of the mixer is connected. Sound field microphone recordings and other coincident one-point shots always result in a very small "sweet spot".

The sound in the cinema equivalent (if any ) usually only a few places in the exact idea of the sound producers of the film. A wider exact reproduction can be achieved with the wave field synthesis.

Several static approaches exist to increase the sweet spot. A discussion can et.al. in Merchel be found. Alternatively, the optimal listening area can be also tracked the listening position dynamically. Thereby a stable phantom source location for a single receiver can be achieved. This approach is taken in the project Sweet Potter. Program and open source code can be downloaded from http://www.sweetspotter.de.

Sports

In racquet sports such as tennis, badminton, etc., an area in the string bed of the racquet is called sweet spot. This area does not necessarily lie in the geometric center, but can vary depending on the construction of the racquet also closer to the neck or closer to the head. Also, the size and shape of its extension must not round but can be oval. If the ball is hit with the sweet spot, you can reach maximum acceleration and accuracy. At the same impact shock and vibration are optimally damped, which is not the case with hits outside of the sweet spot.

Sweet spot is also in May 2005 for a large-scale tennis initiative to help the German tennis in the coming years to a renaissance. It was founded on the initiative of the Association of German Sports Retailers Association ( vds ) and unites multiple partners from the tennis associations, media, trade associations, industry, and trade shows. The stated goal of the initiative is to bring the sport of tennis in Germany again forward and reverse suffered in the course of the past decade Members and image loss.

In golf, the sweet spot is the point on the clubface where the golf ball is hit perfectly. The same is true in baseball.

When the setting of the inline regulator paintball a marker is referred to the optimum value as the sweet spot. In this case, the working pressure of the marker is set so that the speed of the ball do not exceed the maximum permitted speed of the field operator.

When riding the "sweet spot" is reached when the right combination of relaxation, energy and balance is achieved within a lesson. The "Sweet Spot " stands for the harmony within the body.

Physics

In physics, the sweet spot is the point can be received perfectly to the electromagnetic waves. In RFID, for example, the sweet spot is the area in which a RFID tag can be best read out.

Camera Lenses

When a camera lens sweet spot is that aperture, wherein a lens reaches its best sharpness and optimum contrast. With zoom lenses, the optimum focal length is designated by the same term, ie how far the lens must be extended in order to achieve maximum sharpness.
