Comparison of Audio Spotlight and Hypersonic Sound to a sound arrays such as the Dakota Array
| Audio Spotlight and Hypersonic Sound System | Dakota Sound Array | |
| Aesthetics | The Audio Spotlight transducer is easier to hide than Hypersonic Sound or the Dakota Array. Hypersonic Sound is 3.5" thick and considerably smaller than the Dakota. | The Dakota Array is 3" thick x 36" x 36". While considerably harder to hide than the Audio Spotlight and impossible to "flush" mount, it should blend in as well as Hypersonic Sound. |
| Ease of Installation | Audio Spotlight should be the easiest to mount of the group. Separate amplifier yields a lighter weight and well thought out system for flush mounting. Hypersonic Sound is considerably smaller and lighter than Dakota Array. Flush mounting is a good option. |
Dakota Array is much larger and heavier at 75 lbs. than either of the other products. Because the array is built with standard style speakers, there must be some distance behind the array, so flush mounting is not possible. |
| Directionality of Sound Emitted | Audio Spotlight and Hypersonic Sound emit a "beam of sound" that is 95+% directional. The beam is very narrow, so units can be placed within inches of each other, to create the effect of multiple zones of sound just inches apart. The ultrasound does not add to the overall sound volume (level of noise) within a room. | When heard side by side with an Audio Spotlight or Hypersonic Sound, the Dakota Array appears to be about 60-70% directional. The standard sound emitted from several arrays will add together to make the background audio level or noise level in a room much louder. |
| Sound Quality | Frequency Response - 600 Hz - 22 KHz for HSS or 18" Audio Spotlight. 300 Hz - 22KHz for 24" Audio Spotlight. With the Audio Spotlight 18" or Hypersonic Sound there is little perceptible Bass below 600 Hz (below 300 Hz for Audio Spotlight 24"). Both of these units emit treble signals to the highest part of the perceptible human hearing range (through 22 mHz). |
Frequency Response - 80 Hz - 15 KHz. The Dakota Array has a fuller, more natural sound than either of the ultrasonic sound systems. However, the frequency response of the Dakota may seem a little flat as the high end of the range is 15 KHz and the average human hears sounds beyond 20 KHz. |
| Cost |
For creating a small zone of sound, as small as 18" x 18", near a kiosk for instance, or in a very quiet area of a museum, we think that the clear choice is the Audio Spotlight or Hypersonic Sound System. The beam is very small and directable. In addition the sound from the beams will not add to the background noise within the rest of the environment, raising the overall noise level of the room.
For areas where a larger zone of sound is required and background noise levels are considerably higher, the Dakota Array may be a good choice.
