Impact and Airborne Noise Explained
When soundproofing your West Sussex home or office, it’s essential to understand the distinction between airborne noise and impact noise. Although both types of noise are disruptive, they behave differently and, as a result, require specific treatment methods. By identifying the source of the sound, you can choose the most effective solution. Therefore, understanding the basics is the first step toward a quieter environment.
Airborne Sound: What Is It and How Does It Travel?
Definition:
Airborne sound moves through the air in the form of pressure waves. These waves originate from the source and travel freely unless blocked or absorbed. As a result, they can easily pass through poorly insulated spaces.
Sources:
Typical sources include human voices, television audio, barking dogs, and household appliances like blenders or vacuum cleaners. Additionally, music systems or loudspeakers contribute significantly to airborne noise.
Transmission:
Sound enters adjacent spaces through doors, walls, ceilings, or floors. Thin building materials or gaps around fixtures allow these waves to spread quickly. Because of this, airborne noise often travels farther than expected.
Measurement:
To evaluate airborne sound insulation, experts compare the decibel level in the source room with the receiving room. A larger drop indicates better performance. Moreover, this helps determine where improvements are most needed.
What Is Impact Sound and How Does It Travel?
Definition:
Impact sound occurs when one object hits another, transferring vibrations through a solid structure. Unlike airborne noise, it does not move through air—it travels directly through materials.
Sources:
Footsteps, dragging furniture, dropped items, and slammed doors are all common causes. Furthermore, these sounds are particularly noticeable in multi-storey homes and apartment buildings.
Transmission:
Vibrations spread through walls, floors, and ceilings, reaching neighbouring rooms. Because the structure carries the sound, standard insulation isn’t always enough. Therefore, specific decoupling methods are necessary.
Measurement:
Specialists use a tapping machine to simulate repeated impact on a floor. The noise level recorded in the room below determines insulation quality. In addition, ongoing testing helps ensure compliance and consistency.
How to Soundproof Against Airborne and Impact Noise in West Sussex
To reduce noise effectively, tailor your approach to the specific problem. Fortunately, West Sussex Soundproofing offers expert solutions for both airborne and impact noise.
To reduce airborne noise:
-
Increase the mass of walls, ceilings, and floors using mass-loaded vinyl, acoustic plasterboard, or soundproof panels.
-
Fill wall cavities with acoustic mineral wool to absorb sound energy.
-
Additionally, seal all cracks and joints using acoustic sealants to prevent sound leakage.
-
For external noise, install soundproof windows and doors that block outside disturbances.
To reduce impact noise:
-
Install floating floors to isolate vibration and reduce sound transfer.
-
Use resilient underlays, rubber mats, or thick carpets with underpadding for effective shock absorption.
-
Moreover, apply resilient channels and decoupling clips to walls and ceilings to break the path of vibration.
Although each noise type requires different techniques, a combined solution often works best. Not only does this improve comfort, but it also adds long-term value to your property.
