But concerts have high acoustic demands. Open side, back and upper stages are not advantageous – the solution: mobile concert rooms! With towers and ceiling sails, an enclosed space is created on stage which reflects the orchestral sound and diffuses it differently. The result is an unadulterated sound that is conducted naturally into the auditorium.

Then the individual towers are moved to their place with a special manual mover and the wings of the towers are unfolded – finished. The concert hall is now ready for the concert performance.

Just one person can quickly set up the acoustic walls. After the performance, the Legacy is dismantled just as quickly as it is erected and can be stored compactly folded away – until the next use. ![Set up of mobile acoustic walls as an acoustic support for a performance](https:// www.hoac.com/wp-content/uploads/sites/6795/2022/04/05_Lagacy.jpg) ![Mobile acoustic walls hanging from the ceiling ](https://www.hoac.com/wp-content/ uploads/sites/6795/2022/04/06_Kundenprojekte-1.jpg) ## **HOAC^(®)** projects worldwide [Our projects ](https://www.hoac.com/projects/acoustic-shell/?output_format=md) ## Let’s talk about your ideas!
