What is Soundproof and Sound Absorption


Soundproofing :

Soundprofing refers to the process of blocking external noise and preventing it from entering. It’s about creating a barrier that stops sound waves from getting through walls, floors and ceilings. Soundproofing aims to establish a calmer,more serene environment by minizing external nosie disturbance.


Sound Absorption:

Sound absorption involves managing the acoustics within an enclosed area. Rather than blocking sound, it’s about absorbing sound waves to reduce echo and reverberation. This improves the acoustics of a room making it more pleasant and clear. Sound absorption is particularly important in spaces where sound clarity is key like recording studios, theaters and auditoriums.

  • Principal distinctionsBetween Soundproofing and Sound Absorption:
Soundproofing Sound absorption
Objective Blocks external noise from getting in or out. Reduces echo and reverberation.
Material used Uses dense, heavy materials like MLV, double glazing and insulated walls. Uses porous, soft materials like acoustic foam, carpets and fabric panels.
Applications handy, if you want a bedroom, office or home theatre to stay private and quiet. Essential for spaces where sound and noise are important, such as studios, hall, and meeting rooms.

Types of Noise

Regarding soundproofing and sound absorption,a crucial aspect is comprehending the diverse categories of noise. Noise can be classified according to its source and how it spreads through various surroundings. The following are the primary forms of noise you should be aware of:

1. Airborne Noise

Noise transmitted or propagating through the air is known as airborne noise and it ranges from conversations, music, television, and traffic noise. This noise invades homes through opened windows, doors, crevices and any other possible gap. It is especially annoying in apartments where party walls are common and therefore enhances the level of disturbance.

Examples of Airborne Noise:

  • Conversations and shouting
  • Music and television sounds
  • Noise of traffic and passersby
  • Dogs barking and other animals-related noises


2. Impact Noise

Impact noise is produced in an area where one surface strikes or hits another resulting in repetitive vibrations of structures. This type of noise occurs in residential dwellings such as apartment blocks or hotels, where sound such as footsteps, movement of furniture or items falling can be heard from one floor level to another.

Examples of Impact Noise

  • Sounds of footsteps on the wooden and concrete surfaces
  • Dropping objects
  • Moving furniture
  • Slamming doors


3. Structure-Borne Noise

Structure borne noise is sound whose energy gets into a building’s fabric and propagates as structure-borne waves. This noise may come from plumbing system, AC system or elevator among others which are mechanical structures. It can also be in the form of impact noise and may at a certain time develop into structure borne noise as it passes through the structure.

Examples of Structure-Borne Noise:

  • Faucet sounds (rushing water and pipes)
  • Any external noise that originates from your HVAC system such as from the fans or compressors.
  • Such vibrations including from generators, vehicles, and other heavy appliances.
  • Elevator operations


4. Environmental Noise

The noise that enters into the enclosed space of a building from a different location is known as the environmental noise. Such sounds may include car horns, construction work, airplanes flying over heads, and noise from weather systems. Road traffic noise is still a big problem with the advancement of technology and our increasing interaction with busy environments.

Examples of Environmental Noise:

  • Traffic and roadwork
  • Airplanes and helicopters
  • Construction activities
  • Natural sounds related to the climate
