The Sound of Silence.

A good recording isn’t just about having the right kind of microphone, although it does play an important part. Getting the right sound depends greatly on the acoustic of the room that you are recording in. Once we cracked the set up that would give us the best chances for a great recording we began trialing and recording some initial takes. Upon listening back, we realised that the microphones were picking up reflected sound of the voice bouncing off the walls in our home studio. This caused the recordings to sound boomy and the overall balance felt at odds with what we wanted to achieve.

We realised that we needed to find a way to soundproof the room and absorb some of the reflected sound. We knew from our shared experience of recording in professional studios that they manage this challenge through the use of carefully placed acoustic panels, curtains, and carpet. When done correctly this can absorb sound and provide a dry acoustic needed for recording. But how on earth do you soundproof a room during Lockdown using only household items?

Luckily before we were housebound, George alongside his brother created some homemade acoustic panels during his last trip to Romania. These were originally intended to absorb sound so that the noise pollution to our neighbours was lessened. They are made from fabric, plywood, and mineral wool. I’ll share with you the method they undertook. After deciding what size you want the panels to be, we chose 25cm2, Step One is to create a wooden frame which is as deep as your pieces of mineral wool. Step Two is to cut the mineral wool so that it fits snuggly inside the frame.

SIDE NOTE: please make sure that you are using gloves when handling mineral wool as it has small bits of fiberglass that can scratch the skin. We bought 50cm x 100cm piece of mineral wool, which was enough for all four frames. Step Three is to measure out your fabric so that it covers the front and the sides of the frame, with a bit of extra material so that it can be secured to the back. Step Four is to secure your fabric to the frame using your method of choice, George used nails but staples or a strong glue would also suffice. Step 5, once you are happy with the position of the fabric, place a square of plywood, a little smaller than the frame, on to the back for a clean finish. This piece of plywood can be attached with nails, staple gun or glue. An Ikea hack if you do not have access to saw or spare plywood, would be to use a RIBBA frame from Ikea without the glass. I think these will be perfect as they are about the right thickness and you will not need to worry about endless measuring as they will all be uniform. Hooray for symmetry! If we make more in the future I will try this method and make an instruction video.

So back to Sound Proofing the room! We stuck these panels above the keyboard as that is where my voice would normally hit when practicing. However, we didn’t make enough of them to cover the entire wall of the studio. This meant that we had to improvise and create a little vocal booth.

We had the perfect space in mind, as the entrance to our home studio forms a little square alcove. We wanted to enclose this space and so our minds began-a-turning. I personally love having small spaces well organised and in our utility closet, we made use of Telescopic Garment Racks so that we can hang our clean clothes above the washer/dryer. One afternoon we decided to take the racks down and create a scaffolding effect to aid the vocal booth. We hung a suspension rail above the door, from which we hung one blanket. Then we assembled two vertical poles, which supported a horizontal rail, from which we hung a thicker throw. Between the two assembled structures we carefully balanced a spare rail and a final blanket. Each blanket was secured using bulldog clips and hairdresser sectioning clips.

Voila! The booth was born.

Out of excitement we began recording and found that the difference was tremendous. The voice no longer sounded like it was recorded in a bathroom and the balance was clean and had clarity. We were really thrilled!

Next Week we will share with you the next step of process – THE RECORDINGS, which I will title “Getting it done!”
