Projector Noise Box
The idea for Stouenborg's projector noise box was born out of a desire to minimize the noise from projectors in an auditorium located in the Mærsk Tower. The noise reduction boxes for projectors available on the market at the time were large and visually dominated too much of the room. At the same time, they required a continuous supply of large amounts of fresh air, which made their use difficult.
Based on the acoustic reflection effect that occurs within a box, Stouenborg's technicians sought to determine the ideal shape that would achieve the most significant possible attenuation of noise from the projector's fan and other mechanical components. After calculations and several prototypes, Stouenborg's projector noise box was given its final distinctive shape, which differs from similar products on the market with its compactness and angular expression. The shape helps ensure optimal airflow inside the box, preventing the projector from overheating. Depending on which projector is mounted in the box, between 10 and 18 dB of attenuation can be achieved, resulting in a significant reduction of the noise level without affecting the projector's functionality.
The projector noise boxes are particularly suitable for sound-sensitive environments such as auditoriums, conference rooms, concert halls, theatres, and churches, where even low noise levels can be distracting. The boxes can also be useful in theatres to improve the audience experience. For example, at Østre Gasværk Theater, where 25 projectors are part of the theatre's permanent TheatreMax installation, the boxes are used to ensure that the noise from the projectors does not become a disruptive element during performances.
The boxes are made of robust materials with high sound insulation and a user-friendly design that facilitates both easy installation and easy access for maintenance and adjustment.
Stouenborg himself uses projector noise boxes for live projects, including in concert halls, churches, and other acoustically sensitive environments, where maximum noise attenuation is necessary to provide the best possible experience for the audience.
Stouenborg has also designed and produced other products in connection with a project that required special solutions. You can read more about the different solutions here.
