Several months ago I started work on a project to contain the sound of a drummer in a residential home. This type of project is pretty typical. The part of the project that wasn’t typical was that the drum isolation needed to be removable in a couple of hours so that the space could be used for other purposes.
Detail of the latch and edge of the isolation acoustic door. We laminated the acoustic doors from scratch with 5 layers of MDF damped with Green Glue and bonded with polyurethane glue. The outer frame of the door is laminated poplar using floating tenon joinery for maximum strength and stability. The door is 2 1/4″ thick requiring both specialized hinges and a custom leverset. The weight, feel and sound of the door is perfectly satisfying. The door weighs enough to stop sound, but it’s light enough to be easily moved by two people.
The view from inside the booth looking at the second wall of gobos with the second acoustic door closed.
A detail of the inside top of a gobo. The 4 inch broadband absorber stops just below the bolts that press against the ceiling and push the gobo into the floor. The bolts are 5/16th that require a 1/2″ hex driver or socket.
A detail of the four gobos that make up the second wall from the outside. The gobos have been printed with a high quality oil based primer to minimize moisture effects on the MDF (medium density fiberboard.)
A view of the track lighting, the music stand and the structural pillar to which the gobos bolt.
The view from outside the second wall back through the booth into the joined storage closet.
A detail of the threshold. The entire for frame attached the the gobos on either side and is pressure fit against the ceiling. The entire door, frame and all is removable.
This is the same perspective with the door open.
This is the view of the ISO both coming down the basement stairs. You can see the array of gobos and the heavy acoustic door with 4 heavy duty EMTEK hinges.
Looking into the ISO booth from the basement floor. You can see the drums set up with a music stand.
