Studies carried out at the University of Munich showed that, with the same stroke impulse, the isolated tuning frame (in this case, with a synthetic skin and a basic tone of 90hz), can generate a higher loudness (volume perceived by the human ear) (solid line) than a classic tuning frame. The diagram shows five individual strokes for the same drumskin, the same basic tone, and the same stroke impulse.
In addition to the isolated, rubber-coated pressure point, each isolatHED tuning frame also has a regular, traditional pressure point (the second, small black point next to it). When the tuning frame is entirely relieved and can be loosely rotated, it can be isolated either completely or partly by shifting to the relevant pressure point.
This gives (experienced) players the opportunity to experience the different sound/vibration behaviour of each pressure point.
In both cases, the tuning frame remains separated from the outer drum frame. Only for the traditional pressure point, there is a higher level of structure-borne sound transmission due to the tuning mechanics, which is prevented for the rubber-coated pressure point.
A traditional pressure point can, for example, be useful if the drumskins are very uneven or thick. Since, however, most players perceive the entirely isolated pressure point as a considerable sound improvement, our drums are delivered with the isolatHED pressure point position.
Players who aren’t that experienced don’t have to worry about the second pressure point.
"I am always looking for a clear and defined tone in my drum. When Christian first told me about IsolatHED tuning rim, I was intrigued: could this be the next big thing? And it proved to be the next big thing, both in the laboratory testing but also when I tested it in person."
"From improved accuracy and ease of tuning to overall improvement of sound from my existing skins, the IsolatHED tuning rim has taken a great drum and made it better. This is an excellent addition to the ChangeHED system."
"Drum is very good. At first I didn't like it as it was almost too bright and didn't feel as controlled but as soon as I went into the studio it was instantly better. Open notes sound mega!! Night and day compared to the drum I was playing. I used it for 3 days in the studio and couldn't go back to the other one. So that's a clear thumbs-up from me!"
"I was instantly convinced! The skins react even more sensitively now, tone modulation is even more precise, and the sound is even louder and clearer, too! With the new technology, I’ll be able to play even more dynamically, and as a bonus, the drum will be better heard when I’m playing with the band. All of these improvements also make a considerable difference when using a microphone. Even our sound engineer is a fan of isolatHED!"
