The SteinMusic H-Pro Acoustic System is a very efficient system for optimizing room acoustics. It is specially designed for use in concert halls and consists of active and passive components. Their interaction optimizes the acoustic conditions, for the musician as well as for the listener. For the former, it is easier to express their playing, and the listener can follow the musical events better. Because the sound carries better and is thereby also more understandably perceived. The SteinMusic Hpro Raum Acoustic System consists of active and passive elements, which have a positive influence on the acoustics.
Air as a medium of sound transmission The basic requirement for the transmission of sound waves is a medium that can transport them. When playing music, this medium is air. Air is known to have a multitude of properties: Pressure, compressibility, temperature, humidity, oxygen content, charge, odorous substances, or other suspended matter. But above all, air has one thing: mass. More precisely, 1.293 kilograms per cubic metre.
A concert hall such as the Elbphilharmonie Concert Hall with 2100 seats and a volume of 23,000m3 thus comes to about 30 tons of room air. These air masses do not have to be moved completely to transmit sound, but their inertia is still involved.
On the other hand, the vibrating components of the instruments, some of which have masses of only a few grams, have to transport their vibrations through the large air volumes.
The Hpro system in comparison to classic acoustic solutions The Hpro system is designed to complement classic acoustic solutions. However, it is also an effective alternative where the use of damping elements and diffusers is not possible for structural or optical reasons.
Why does the SteinMusic Hpro system work in large halls as well as in small rooms, where the air mass is much smaller? Experience shows that two phenomena occur when using the SteinMusic Hpro system: First, the air “carries” the sound better, which also leads to the common statement from musicians that it is easier for them to play or sing their instrument.
The direct feedback of one’s actions via the auditory system is more direct, as is the perception of this by the audience. On the other hand, the reflection behavior at the interfaces changes.
Small rooms and even cars are acoustically perceived as much more spacious when using the Hpro system. Which significantly increases the general well-being.
