Soundproofing and sound isolation in Kenya

Sound isolation (soundproofing) stops sound travelling from one space to another: from a church into the homes next door, from a club into a hotel room, or between two events running side by side. It is different from acoustic treatment, which controls echo inside a room. Most noise complaints need isolation, not more panels on the wall. Sound Creations designs and installs both, and we will tell you which one your problem actually needs.

Isolation or treatment: which do you need?

• Neighbours can hear you, or you can hear them – that is an isolation problem. Sound is escaping through walls, roofs, doors, windows, floors or ventilation.
• The room itself sounds echoey, boomy or unclear – that is a treatment problem. See Acoustics and Acoustic panels and ceilings.

Acoustic foam and wall panels absorb sound inside a room, but they do very little to stop it passing through a wall. Many spaces need both, designed together.

How sound isolation is done

Sound finds the weakest path. Good isolation deals with every path, not only the obvious wall.

• Mass. Heavier, denser constructions block more sound. Adding layers of dense board or masonry raises the isolation of a wall or ceiling.
• Decoupling. Separating the two sides of a wall or ceiling (resilient mounts, independent stud frames, a room-within-a-room) stops vibration travelling straight through the structure. This matters most for bass from music and sound systems.
• Sealing air gaps. Even a small gap leaks a surprising amount of sound. Gaps around doors, service penetrations, cable routes and the tops of partitions must be sealed with suitable acoustic sealants and details.
• Doors and windows. These are usually the weakest elements. Acoustic doors with proper seals, lobbies (two doors in series) and laminated or double glazing make a large difference.
• Floating floors. Where impact noise or heavy bass reaches the rooms below (gyms, clubs, studios on upper floors), a floor built on resilient isolators breaks the path into the structure.
• Ventilation and air-conditioning (HVAC) paths. Ducts and open vents are direct sound paths. Lined ducts, silencers and acoustic louvres let air through while limiting sound.
• Dividing doors and operable walls. Large halls can be split into separate rooms with acoustic dividing doors, so several events can run at once.

Typical situations we see in Kenya

• Churches close to homes. Worship music and amplified sermons reaching neighbours, often through open windows, roof sheeting and gaps under eaves.
• Clubs, bars and restaurants. Noise complaints from residents or nearby hotel rooms, especially low-frequency bass at night.
• Recording and rehearsal studios. Keeping traffic and neighbours out and the music in, so recordings stay clean.
• Offices and boardrooms. Speech privacy between meeting rooms, executive offices and open-plan areas.
• Hotels and event venues. Quiet guest rooms near function halls, and halls that divide into smaller rooms.

How Sound Creations approaches an isolation project

1. Site survey. We visit, listen to the problem at the times it happens, and identify the sound paths: walls, roof, doors, windows, floors and ventilation.
2. Measurement. Using acoustic test equipment, we measure the noise levels involved so the design targets a real figure rather than a guess.
3. Design. We specify the constructions, doors, glazing, seals and HVAC measures needed, and explain the trade-offs in cost and space.
4. Installation and verification. Our team installs or supervises the works, then checks the result.

Our approach treats acoustics as an engineering discipline: measure, analyse, design, treat and verify.

Project example: Sarit Expo Centre, Westlands, Nairobi

The Sarit Expo Centre is a 3,300-square-metre, column-free venue that needed to host several concurrent events, with an exhibition room seating up to 7,000 and a meeting area for up to 500 working side by side. Sound Creations supplied acoustic wall panels, acoustical ceilings and specialised acoustical dividing doors that subdivide the exhibition hall into separate rooms, so concurrent events can run with distinct audio requirements and no sound spilling between them.
