Understanding and Reducing Noise in Buildings

Comfort and functionality are essential in design—so is effectively managing noise pollution. Below are the three main types of building noise and targeted strategies to control each one:

1. Airborne Noise

Airborne noise travels through air—think voices, music, TV, or traffic—often passing through walls, ceilings, and openings.

Characteristics

• Transmitted through vibrating air molecules.
• Common sources: conversations, media, traffic, appliances.
• Enters via gaps, thin walls, and poorly sealed openings.

Effects

• Disrupts sleep and lowers productivity.
• Causes stress, irritation, and loss of concentration.
• Compromises privacy with overheard conversations.
• Long-term exposure can impact mental health.

Solutions

• Soundproofing materials: acoustic panels, carpets, heavy curtains.
• Sealing gaps: improve door and window insulation.
• Structural upgrades: thicker walls, double glazing, insulated floors/ceilings.
• Acoustic barriers: partition systems like Biwall or Trywall.

2. Impact Noise

Impact noise (or structure-borne noise) occurs when objects strike surfaces, sending vibrations through the building’s structure.

Characteristics

• Comes from actions like footsteps, moving furniture, or slamming doors.
• Travels through solid materials: floors, walls, ceilings.

Effects

• Interrupts daily life and sleep.
• Reduces focus and productivity.
• Causes general discomfort and stress.

Solutions

• Floating floors with resilient underlayers.
• Acoustic underlays, like Basewood, Grei, or Upgrei.
• Carpets/rugs on hard flooring.
• Resilient mounts for equipment (e.g. Megafoot).
• Sound panels such as Rewall or Mustwall in partitions.

3. Vibration Noise

Vibration noise stems from mechanical vibrations (like HVAC systems or pumps) transmitted through structural elements and radiating as sound.

Characteristics

• Originates from vibrating equipment or structural components.
• Propagates through materials like steel, wood, or concrete.

Effects

• Potential structural fatigue or damage over time.
• Causes occupant discomfort and distraction.
• May affect sensitive equipment and concentration.
• Persistent issues can reduce property value.

Solutions

• Vibration isolators: pads or mounts such as Megamat or Megafoot.
• Damping materials: rubber, cork, or specialized compounds.
• Proper installation of mechanical systems.
• Floating structures to isolate vibrations.
• Decoupled design or added mass for vibration mitigation.
