The Role of an Acoustic Consultant in Infrastructure Projects

With increasing air, rail and road traffic, the creation of uninhabitable areas due to noise has become a critical concern. Noise management is now an integral part of transport infrastructure investments. 

This is where acoustic consultants come in. Their expertise and advanced technology minimise noise disturbances, creating a harmonious environment for both the infrastructure and nearby communities. By offering their services, acoustic consultants contribute to sustainable and livable urban spaces, being an essential part of large transport infrastructure projects. In this article, we will explore the vital role of acoustic consultants in transport infrastructure projects and the services they provide.

Acoustic Consultant’s Primary Responsibilities

 The primary role of an acoustic consultant is to supervise the investment process, specifically overseeing the acoustics for all components of the project. In conjunction with selecting the designer, main contractor, and design office, it is essential to engage an acoustic consultant to provide comprehensive oversight and develop acoustic guidelines for various industries.

Thorough acoustic supervision is crucial for projects situated in specific locations, as it allows for the minimization of risks associated with noise emissions. Furthermore, it serves as a vital element in determining the guaranteed technical parameters outlined in contracts and agreements.

Given the scale of large projects, it is highly recommended to work within an integrated acoustic model. This approach involves the coordination and management of individual components of the investment, such as road, railway, and air segments, through one unified model. The acoustic consultant is responsible for overseeing and managing all integrated models, ensuring they function harmoniously within the larger framework.

During collaboration with individual contractors, contractors submit their respective acoustic models in the form of program source files once their work is completed. The consultant then meticulously examines the settings and assumptions of each model and integrates them with the overarching acoustic model.

To facilitate an efficient process, it is essential that all work is conducted within a single acoustic calculation program. This streamlined approach is similarly employed for investments in industrial plants within the petrochemical industry, enhancing the management of the acoustic model.

By adhering to these practices and leveraging the expertise of an acoustic consultant, construction companies, state administration, and authorities can ensure comprehensive acoustic supervision, minimise noise-related risks, and achieve desired technical parameters in infrastructure investments.

Secondary Responsibilities of an Acoustic Consultant

In addition to overseeing the acoustics of an investment, an acoustic consultant takes on various secondary responsibilities. These tasks contribute to the project’s success and ensure effective noise management throughout the construction process, while also meeting the specifications outlined by the CEO, directors of construction companies, state administration, and authorities.

One significant secondary responsibility is the determination of design requirements for infrastructure, buildings, and devices, as well as the selection of appropriate acoustic solutions. Working closely with the investor, designer, and acoustics specialist, the consultant defines the acoustic requirements for each project element, thereby establishing the guaranteed technical parameters outlined in contracts and agreements.

To support this process, the acoustic consultant expands the database of examples and concepts of acoustic protection for various types of noise sources. This aids in defining the minimum acoustic requirements for individual components of the project, progressing from a general overview to detailed large-area and local acoustic analyses, which may include auralization capabilities.

Preparing concise and accessible documents and presentations that address various acoustic issues related to the project is another crucial responsibility. These materials facilitate effective communication with stakeholders, including the local and national society, during public consultations and educational activities. By presenting noise-related information in an understandable manner, the acoustic consultant ensures proper engagement and addresses public comments regarding noise concerns.

Monitoring noise levels at designated reference points throughout the investment process is also essential. This provides ongoing knowledge about the acoustic climate, allowing for the assessment of the impact of individual components and the identification of necessary changes. Understanding the existing acoustic background level for the investment site is crucial, as it serves as a baseline to evaluate additional noise impact.

Additionally, conducting noise workshops for project teams and providing training in acoustics to management staff are vital components. These initiatives ensure that relevant personnel, from various departments such as legal, engineering, purchasing, quality, and marketing, understand the intricacies of noise assessment and management. Specifically, the training materials address the assessment of nuisance using High Annoyance (HA) indicators, as people may express complaints about excessive noise, even when sound levels remain within permissible limits, particularly in rural areas.

By fulfilling these secondary responsibilities, an acoustic consultant enhances the overall project implementation, maintains effective communication, and ensures compliance with noise regulations and community expectations.


In conclusion, the role of an acoustic consultant in transport infrastructure projects is crucial for effective noise management and ensuring a harmonious environment for both the infrastructure and surrounding communities. Through their primary and secondary responsibilities, acoustic consultants provide valuable services that contribute to the success of the investment.

By engaging the services of an acoustic consultant, authorities and management can rely on their expertise to navigate complex noise challenges, meet technical parameters, and foster positive community relationships. Ultimately, the involvement of an acoustic consultant is essential for the successful implementation of transport infrastructure projects and the creation of a noise-conscious and enjoyable built environment.
