My name is Austin Chase and I’m a new sound editor here at Transported Audio! Eric brought me aboard in August and it’s been a wonderful first few months. I’ve already had the pleasure of working on numerous exciting and unique projects during my time here. These include over a dozen Star Wars Battlefront II videos, some intense repairing of dialogue recorded in the 1960s and, more recently, designing and building a custom projector hush box for our studio! This blog post will primarily focus on the hush box project.
The purpose of this project was twofold: to keep the client projector at a low temperature, and to prevent the noise of the projector from becoming a distraction in our studio.
Projectors are essentially big lights that create a ton of heat and, in turn, need big fans to keep them cool. The easiest way to minimize this fan noise is to contain the projector inside a sound-insulated box. However, enclosing the projector also insulates heat, so it’s necessary to create an intake/exhaust airflow system using computer fans. The bigger the fan blade, the slower and quieter you can run the fan. The downside to this is that it creates bigger holes in the box itself, allowing more of the projector’s fan noise to escape. To solve this, airflow channels must be created to keep air moving in the right direction and contain the noise where it belongs: inside the box and away from the ears of anyone in the studio.
