Airborne Sound Insulation Testing: Ensuring Acoustic Comfort & Compliance

Building Acoustics measurements Thailand

Thansmission of sound from a source room to adjacent rooms and to the outdoor environment (or vice versa) is a major concern in the design and planning of industrial premises and residential properties alike.

Air-borne transmission has been studied extensively at Geonoise Thailand. We have performed many studies, managed the implementation of the measures and performed noise control measurements afterwards to check the results and get the optimum correlation between calculations and results.

From this practical approach we can predict very accurate what the outcome will be of the building acoustical projects that we handle.

If you want to consider improving noise control of a single room in a house or in a hospital, hotel, residential (mixed with offices, parking, shopping etc.), we are the right consultants for you.

Airborne Sound Insulation Testing: Ensuring Acoustic Comfort & Compliance


In today’s bustling world, noise pollution has become a significant concern for many. Whether it’s the hustle and bustle of city streets or the hum of machinery in industrial areas, unwanted noise can disrupt peace and tranquility. This is where airborne sound insulation testing becomes invaluable. Not only does it ensure acoustic comfort, but it also plays a pivotal role in meeting regulatory standards.

What is Airborne Sound Insulation Testing?

Airborne sound insulation testing assesses the effectiveness of partitions, walls, floors, and ceilings in preventing the transmission of airborne noise from one space to another. This type of noise includes conversations, TV sounds, or music – sounds that travel through the air and can penetrate building elements.

Why is Airborne Sound Insulation Testing Essential?

  1. Regulatory Compliance: Many jurisdictions mandate specific sound insulation levels for residential, commercial, and industrial properties. Regular testing ensures that these standards are consistently met, safeguarding property developers from potential legal complications.
  2. Enhanced Living and Working Conditions: Effective sound insulation promotes a healthier living and working environment, reducing stress levels and improving overall well-being.
  3. Property Value: Good sound insulation can enhance a property’s market value, making it more appealing to potential buyers or renters.

The Testing Process

The airborne sound insulation test is a comparative process that measures:

  1. Background Noise: This is the noise present without any additional source of sound.
  2. Sound Levels: Using specialized equipment, sound levels are measured in both the source and receiving rooms.
  3. Sound Difference: The difference in sound levels between the two rooms provides a clear understanding of the insulation’s effectiveness.
  4.  Reverberation time: we have to correct the acoustic state of each room to compare it with a standard room

After the data is collected, the results are compared to regulatory standards to ascertain compliance. We measure and comply with international standards for airborne sound insulation measurements such as ASTM, ISO,DIN, JS, etc.

Improving Airborne Sound Insulation

If a property fails to meet the required sound insulation standards, various interventions can be employed:

  1. Adding Mass: Increasing the weight of the partition, often through additional layers of materials like drywall or acoustic panels, can help reduce sound transmission.
  2. Sealing Gaps: Even minor gaps or cracks can significantly compromise sound insulation. Ensuring that all joints, edges, and penetrations are sealed can dramatically improve performance.
  3. Acoustic Isolation: Introducing materials that can absorb sound, like acoustic foams or rubber, can help in minimizing sound bridges.

The Role of Professionals

Employing professionals for airborne sound insulation testing is paramount. These experts not only possess the necessary equipment but also bring with them years of experience and a deep understanding of acoustics. Their insights can help property owners and developers make informed decisions about improving sound insulation.


Airborne sound insulation testing is more than just a regulatory requirement. It’s about creating environments where people can live, work, and play without the constant interruption of unwanted noise. As cities grow and spaces come closer together, the importance of sound insulation cannot be overstated.

Whether you’re a property developer, an architect, or a homeowner, understanding the intricacies of airborne sound insulation testing can make a world of difference. The investment not only ensures compliance but also contributes to the overall quality of life for occupants.
