When Airborne Museum Hartenstein in the east of Holland got the green light to renovate and renew their exposition they decided to take the plunge and invested in an "experience". Relatively new in the museum world, this approach allows the visitor to walk through the actual collection, supported by vision and sound. For this project we recorded several native british, german and polish speakers to ensure every detail was correct and believable. The challenge then was to blend these voices with the intense battle sounds we created. In some cases, this required some heavy post-production and testing on site at the musuem.
