In order to acoustically isolate this type of source, high transmission loss walls, windows and doors are required. The laws of physics favor mass in this situation requiring multiple layers of gypsum board, double walls and steel doors. This level of attenuation is beyond the capabilities of wood doors. Engineered products are designed to minimize weight and deliver high in-field noise reduction. Since 1949 IAC has installed more than 100,000 acoustic doors in a wide variety of applications with STC ratings up to STC-70.
Acoustic doors come in many shapes and sizes and varying degrees of assembly.
The IAC Noise-Lock Wood Veneer door is factory veneered with more than 50 species of real wood. The door is field sanded, stained and sealed to match the existing wood finish and architecture. Frames are field cased with wood mouldings to complete the picture. Of course, if the traditional look is not yours, the metal door will provide the high tech look giving the theatre designer a full range of decorative options in between. The IAC Noise-Lock series is a fully factory assembled Access System and is shipped complete with leaf, split frame, seals, hinges and finish hardware.
