U.K. Maritime Museum Equipped With Solid Drive Transducers

Interior of the Mary Rose Museum

MSE Audio distributor Sound Directions U.K. recently completed an audiovisual installation in the newly reopened Mary Rose Museum, with SolidDrive units comprising an important part of the AV experience.

The Mary Rose, a Tudor warship built for the English navy of King Henry VIII in 1510, sank in 1545. Rediscovered in 1971, the wreck of the Mary Rose was raised in 1982 and towed into her home port in Portsmouth, England into a covered dry dock to begin conservation. More than 34 years of conservation work ensued, where for more than 30 years the ship was sprayed with fresh water and wax to preserve the timbers. A permanent museum building was constructed over the ship and in 2013 the sprays were finally turned off. The ship was controlled air dried over the next three years and on July 20, 2016, she was revealed to the public to allow it a completely clear and uninterrupted view.

Originally opening doors to visitors in May 2013, the museum was closed for most of the year while the latest development works were undertaken, to allow full height viewing of the ship from three separate viewing angles. The updated Mary Rose Museum now provides panoramic views of the ship from all nine galleries through floor-to-ceiling glass on the lower and main decks. On the upper deck, visitors enter the Weston Ship Hall via an airlock and are separated from the ship only by a glass balcony.

The latest phase of work included an audiovisual installation to enhance interpretation and visitor experiences; a creative team led by exhibition designers Real Studios was brought in to tell the story of the ship’s crew going about its daily routines both at war and peace.

Projections on the remnants of the Mary Rose

More than 60 short scenes were filmed and produced by Graham English and Company and projection mapped by Sysco AV into the relevant cabins on the ship’s hull. Together with lighting design from Adam Grater of DHA Designs and an accompanying atmospheric soundscape produced by Peter Key Sound Design and Production, the ship is brought to life for the visitor at intervals throughout the day.

Tasked with providing a discreet and unobtrusive audio solution, Peter Key chose to enhance the existing sound installation of overhead loudspeakers in the two enclosed viewing walkways along the main and lower decks. With the ship now in full view, Peter Key said, “I felt that sound should not all be heard from above but should also appear to play from in front of the visitor, in line with the projected images. This meant we needed to excite individual glass panels of the viewing corridor for the entire length. This was quite a tall order; not only was the laminated glass more than 25 millimeters thick, but the solution had to be invisible, so that it did not obscure the view of the Mary Rose.”

Key sought the expertise of MSE Audio distributor Sound Directions, which recommended the use of SolidDrive SD1g units. “Extensive tests proved that such a mass of glass could be excited by a relatively small transducer device to provide good-quality and distortion-free audio,” Key said. “The small form factor and clean cylindrical lines of the devices enabled them to blend into the glazed environment.”

“The SolidDrive SD1 surface exciters provide a very discreet solution for visitor attractions including museums, as they provide excellent quality audio while being almost invisible, particularly when glass surfaces are used for encasing the exhibit,” said Stanislas Boivin-Champeaux, managing director for Sound Directions.

In total, four SolidDrive SD1g units were installed along each deck level over a distance of 40 meters, with each SD1g driven by a separate audio channel of a SolidDrive SD-250 Mini amplifier. Audio reflections from the opposite side of the corridor, behind the visitors’ viewing area, fills in the sound and enables the use of fewer units and amplifier channels than might otherwise be required.

“We are delighted that the combination of sound and projection not only brings the ship to life, but also re-establishes the relationship between the ship and the thousands of real objects in the context gallery walkways,” said Robert Lapraik, deputy chief executive for the Mary Rose Museum.

“I am very impressed with the audio quality from such a small and compact unit,” Key said. “It provides another layer of loudspeaker playback to enable a truly immersive soundscape to be created within the viewing galleries.”
