This is the sixth and final post in a series of blogs to teach you about the key things we have done to make sure the music recording and rehearsal studios at Royal City Studios are completely isolated from each other. We have invested heavily to make sure both sound waves and sound vibrations stay where they belong. The six major aspects to control this are:
Part 5: The Ducts
The Problem
In our last post, we taught you about how we built the studios to keep sound from escaping through ceiling fixtures. But what about the big holes in the ceiling that allow fresh air in, and let stale air out?
The Solution
There are two key components to control sound in the ductwork. This time, both help to manage the actual sound waves, not the vibrations
The first thing we did was add acoustic insulation inside the ducts. With two inches of insulation around the inside of the vents – sound gets absorbed quickly. Check out the photo below to see what this insulation looks like.
In addition to this insulation, we learned something very interesting. For every right angle turn in a vent, you can achieve a 20-decibel reduction in sound! This happens as there is enough straight vent on either side (2 times the diameter), with 10% acoustic lining, you maximize the sound reduction. So, we have introduced multiple “elbows” in the ductwork at every entry and exit point.
Thank You!
This has been a great trip! We have shown you how the music rehearsal and recording studio floors, walls, doors, ceilings, vents, and ducts are designed to keep sound where it belongs. In the future, we’ll share how we keep audio awesome inside the studio while you are rehearsing and recording.
