Throughout 25 years of being a drummer and musician, I have seen many attempts to build soundproofed rooms in order to isolate the leakage of sound from one room to another. The vast majority have been unsuccessful. This is mainly due to the complex nature of the way sound transmits through adjoining and partition walls. From a general contractors point of view, if you ask for a soundproofed partition what you get may in reality only be good enough to stop the transmission of sound from general classroom activities such as banging chairs, footsteps and chatter (around 70-80db). Musical instruments on the other hand are a great deal louder. In particular the drum kit which produces around 95dB - 100dB of sound – this is similar to the noise produced from a pneumatic jack hammer.
Such is the complicated nature of the technical aspect of creating a sound proofed space, I fear that a general builder will not be able to provide the specialist requirements needed for this job, and complete this work to the necessary technical specification.
Being a drummer myself I have always been faced with the problem of being able to practice at home. For this reason, I decided to study the building techniques and materials required to isolate sound from loud sources. A great deal of knowledge on this subject came from a past college lecturer of mine. In 2005 I constructed a drum booth in a single brick garage, which was 100% effective and fully sound proofed. This enabled me to practice anytime of the day or night without disturbing neighbours or people in my own house.
I have been involved with various projects over the past 15 years which have involved designing and building rooms where sound isolation was the primary goal. This has ranged from building a fully bespoke drum studio for ADC drums in Liverpool to private clients who wished to build a ‘room within a room’ configuration enabling them to play loud musical instruments at home.
