Several components go into the holistic creation of a world-class building project. Besides the design of indoor and outdoor spaces, ventilation flows, built-in parking, aesthetic landscapes, and lighting frameworks, an ergonomic approach to acoustics is equally important. Multiple sources of noise and vibrations impact the overall quality of the acoustics of a building and can result in unlivable conditions.
However, with proper attention to noise and vibration control, the acoustics of buildings can be transformed to offer optimal comfort to the occupants, in line with global and local design standards. It can also reduce the contribution to environmental noise pollution levels.

Top Sources of Noise And Vibration

Today, any contemporary building complex is a comprehensive, self-sustaining ecosystem. Here is a snapshot of various sources of increased noise and vibration levels:

1. Equipment noises

Modern building complexes have a comprehensive framework of centralized heating and cooling systems, water pumps, generators, and fresh air and smoke extract fans. The various equipment installed as part of mechanical, electrical, and plumbing (MEP) systems collectively raise noise and vibration levels.

2. Noise Pollution

When apartments are located too close to the source of road and air pollution, or any other source of external noise pollution, it can be a possible sound hazard for the occupants.

3. Inefficient Architecture

Another source of unpleasant sounds is the architectural aspects, such as the poorly designed rooms and internal spaces that increase reverberation. Spaces’ size, shape, and finish contribute to reducing reverberation.

4. Surrounding Noise

Another noise source is the ability to overhear conversations and sounds from surrounding apartments.

Hence, in the design and construction phase, attention must be paid to the acoustics as much as any other functionality.

A High-Quality Acoustic Environment

Acoustic quality is integral to performance spaces. The acoustic environment is an essential contributing factor to the overall livability quotient of the building. Advanced noise and vibration control expertise is required to address the problem at scale. This professional intervention leverages technology and science to deliver a sustainable solution towards increased acoustic integrity of any building space.

Relevance to a Wide Range of Projects 

Acoustics play a role in various kinds of large-scale building complexes. Projects span a wide range of categories. They include residential complexes, malls, large shopping hubs, office complexes, educational institutions, hospital and medical environments, conference centers, and complexes occupied by government bodies.

Some projects, such as sound studios, entertainment complexes, theme parks, museums, and theatres, come with more specific acoustics requirements. Though the needs vary, the basic principles remain the same. The noise and vibration levels must be managed, and a high-quality acoustics environment must be delivered.

A Specialized Function  

Today, the responsibility of ensuring a high-quality acoustical environment lies with the team behind building design and construction. It is considered a key aspect of quality indoor design guidelines of global design certifications. However, acoustic analysis is a very specialized intervention, and many design teams need the know-how to address it. They may need to outsource this specific aspect to a specialist aware of international and local guidelines for various building categories.

Not an Afterthought 

The intervention of your acoustics analysis partner needs to start along with the project when the various functionalities of the building are still being determined. It is an integral part of the foundation of the building and cannot be viewed as an add-on functionality or an intervention brought in as an afterthought. Delays can lead to extensive challenges in the future.

A Systematic Approach

Your acoustics analysis partner will adopt a systematic approach toward the noise and vibration control for the project.

The first step is to categorize various systems and sources of noise and vibration in the building. They will do an in-depth study and analysis of how these sources will impact the occupants and activities of the building. Next, they will develop comprehensive solutions for the design and implementation of controls. Acoustics analysis partners work closely with the core design team to ensure a collaborative and coherent approach to acoustics functionality and its relationship to other functionalities.

Noise And Vibration Control Design 

Once the key sources, systems, and challenges have been identified, your acoustics analysis partner will work on a comprehensive end-to-end design solution that adheres to the necessary standards and guidelines. Building contractors or real estate developers must understand this is an iterative and interactive process. It does not stop once the design concepts are complete, and it is a partnership that continues until the construction and quality testing of the complex is thorough.

The intervention, of course, comes at a cost. However, the prices are much higher when the intervention is piecemeal, delayed, or executed as a damage-control or corrective measure.

Parting Notes 

In 2019, the global acoustics market share was valued at $ 1.22 Billion. As newer building complexes emerge or older ones are redeveloped, the acoustics market size is estimated to grow at a compound annual growth rate of 5.58% to $ 17.30 Billion by 2027.

The acoustics management equipment pivotal in noise and vibration control is becoming more sophisticated and, at the same time, more affordable. Many specialized acoustical analysis services leverage advances in methods, simulation algorithms, and computing power to simulate complex systems with remarkable ease. These interventions are revolutionizing efficient sound transmission in our homes and workspaces.
