This article examines the use of acoustic panels as wall coverings in the television series Star Trek: The Next Generation (TNG), also noting their appearance in the movie "Star Trek: The Undiscovered Country" due to reused sets. Authored by Frank Bitterhof, Jörg Hillebrand, and Bernd Schneider, it provides an overview and detailed analysis of different types of SONEX® and CONTOUR® acoustic panels seen in various TNG locations. Key discussed panel types include: 1. SONEX® One: - Dimensions: 24x48x2 inches (North America), 62.5x125x5 cm (Europe). - Features alternating rows of protruding ("male") and subsiding ("female") elements. - Colors: white, grey, charcoal; transporter room walls painted greenish. - Use: Recommended for larger surfaces, provides uniform wall covering. - Locations: USS Enterprise-D transporter room walls (until season 5), USS Yosemite transporter room, Type-7 shuttle back compartment, Varro ship in Star Trek Voyager. 2. SONEX® Classic: - Dimensions: 24x48 inches (North America). - Available as polyurethane (2-4 inch thickness) or melamine foam (2 inch). - Colors: Polyurethane in charcoal or brown; melamine in white, light grey, black. - Panels split into protruding ("male") and subsiding ("female") pieces. - Use: Suitable for checkerboard or uniform patterns on large surfaces. - Locations: USS Enterprise-D battle bridge ready room, cryogenic Earth vessel "Birdseye". 3. SONEX® Junior: - Dimensions: 24x24 inches (North America). - Melamine foam in white and light gray. - Panels split into "male" and "female" forms. - Use: Best for small surfaces like windows and doors. - Locations: USS Enterprise-D transporter room side wall, USS Enterprise-A transporter room wall. 4. CONTOUR® Spectrum: - Dimensions: 24x24 inches (North America), approx. 59-62 cm square in Europe. - Standard colors in North America include Almond, Arctic White, Black Onyx, Grey Mist; Europe offers white and grey. - Recommended for larger ceilings and surfaces; combinable with other Contour tiles for custom patterns. - Locations: USS Enterprise-D Ten Forward side walls and bar area, USS Yamato ready room, Federation President's office (set reused in "The Undiscovered Country"). - Notable: The starboard Ten Forward panels rotated 90° in season five due to set reuse; this caused continuity errors in the Enterprise series episode "These Are The Voyages." - Also seen in later series like Voyager on Banean homeworld and Hazari ship. 5. CONTOUR® Vision: - Locations: USS Enterprise-D Guinan’s office, Ten Forward bar area, gymnasium; Galileo 5 shuttle lateral wall; USS Enterprise-A sickbay. 6. CONTOUR® Panorama: - Locations: USS Enterprise-D interrogation room (only in episode "The Defector"), holographic dance studio. - Not used in subsequent episodes despite set reuse. The article explains that different sizes correspond to regional standards (U.S. vs Europe), affecting pattern assembly.
