Introduction to hybracoustic
(Hybrid-acoustic organ reflector)As an organist and organ player I always enjoyed the living sound of a church organ.
This living and energetic world of sound used to be impossible to imitate with the use of electronics and loudspeakers.
In 1993 we in Skandinavisk Orgelcentrum started developing a brand new organ concept, where we sort of ”started from behind”.
Both in the US and in Europe there had for years been companies, who produced electronic church organs of unique electronic quality, and which became better year after year.
These organ producers all used ordinary loudspeakers with pressure chamber. For this reason the living sound of the pipe organ could only almost be reproduced.
32 feet hybracoustic cabinet in full length of approximately 10 meters
As a sound reflector an organ pipe has two openings each with a certain spreading:
In the upper end of an open pipe the spread is 360 degrades (totally diffuse), at the labial opening it is approximately 120 degrades. When one or more pipes in an organ house are sounding at the same time, you will get a number of pure physiologic natural interferences, contributing to a tonal movement in the entire sound.
This living and pure acoustic experience can not be achieved with the help of ordinary loudspeaker technology, because the pressure chamber loudspeaker gives a totally ”pure”, but also ”dead” sound. With the development of the hybracoustic sound reflector we have created a concept, making this living organ sound possible!
Each individual sound reflector may be build in sizes from 2 to 32 feet, each with two showing the spread from the well-known organ pipe.
Combined with a special electronic sound creator, where each stop and each tone may be adjusted (intoned), very precisely according to the acoustic peculiarity of the room, the electro – acoustic church organ is now a reality!
The basic tone and ALL overtones are created in the same pipe - exactly as with the model, the organ pipe.
