According to Stratistics MRC, the Global Round Sound Attenuators Market is accounted for $468 million in 2023 and is expected to reach $694.5 million by 2030 growing at a CAGR of 5.8% during the forecast period. Round sound attenuators are acoustic devices designed to reduce or control the level of noise or sound within a specific space by attenuating and dampening sound waves. Round sound attenuators are designed to optimize airflow within ventilation systems, promoting energy efficiency. By minimizing pressure drops and resistance to airflow, these attenuators contribute to the overall efficiency of HVAC systems.

Market Dynamics:

Driver:

Rising focus on energy efficiency

As energy conservation and sustainability become major priorities across industries, round sound attenuators play an important role in achieving energy-efficient operations in ventilation and air conditioning systems. Round sound attenuators are designed to minimize noise transmission while maintaining optimal airflow performance. Additionally, by optimizing airflow, these attenuators help reduce the energy consumption of HVAC systems. As a result, the rising focus on energy efficiency is a significant factor propelling market growth.

Restraint:

Maintenance challenges

Maintenance challenges pose a significant restraint in the round-sound attenuator market. Round sound attenuators, with their intricate internal structures designed for effective sound absorption, may require regular maintenance to ensure optimal performance. Accessing and cleaning the internal components of round sound attenuators can be a complex and labor-intensive process, especially when installed in spaces that are challenging to reach.

Opportunity:

Technological advancements

Continuous innovation and development in materials, manufacturing techniques, and acoustic engineering have led to improved performance and efficiency of round sound attenuators, driving their demand in various applications. Advanced manufacturing techniques, such as computer-aided design (CAD) and computer numerical control (CNC) machining, enable the production of round sound attenuators with precise dimensions, complex geometries, and improved performance. Therefore, technological advancements play a significant role in accelerating market demand.

Threat:

Availability of alternative noise control solutions

As industries and construction projects struggle with noise mitigation challenges, a variety of alternative technologies and materials emerge as contenders against round sound attenuators. These alternatives, including soundproofing materials, acoustic panels, and other noise reduction techniques, may be perceived as more versatile, cost-effective, or aesthetically appealing in specific applications, diverting demand from round sound attenuators. Therefore, the availability of alternative noise control solutions is a significant restraint hampering market expansion.

COVID-19 Impact

The global economic slowdown, disruptions in construction activities, and shifts in spending priorities influenced the demand for round-sound attenuators. Construction projects faced delays or cancellations due to lockdowns, supply chain disruptions, and workforce challenges, directly affected the installation of sound control solutions. Moreover, the heightened focus on health and safety during the pandemic led to changes in workspace design and a reassessment of ventilation systems.

The circular splitters segment is expected to be the largest during the forecast period

The circular splitters segment is estimated to hold the largest share. These devices are designed to evenly distribute airflow within circular attenuators, ensuring optimal sound attenuation performance. The primary function of circular splitters is to redirect and regulate the flow of air through the attenuator, facilitating effective noise reduction. Circular splitters are strategically placed within the round sound attenuators to create turbulence in the airflow, breaking down sound waves and dissipating acoustic energy.

The fiber glass round attenuators segment is expected to have the highest CAGR during the forecast period

The fiber glass round attenuators segment is anticipated to have lucrative growth during the forecast period. These round attenuators with fiber glass linings act as sound absorbers, capturing and dampening sound waves as they pass through the system. The porous nature of fiber glass enhances its sound-absorbing capabilities, contributing to a quieter and more comfortable environment in various industrial and commercial settings. Additionally, fiber glass round attenuators often come with a smooth internal surface, minimizing airflow resistance and optimizing the overall efficiency of ventilation systems.

Region with largest share:

Asia Pacific commanded the largest market share during the extrapolated period owing to rapid industrialization, urbanization, and infrastructure development. As industries expand and urban areas become more densely populated, the awareness and importance of mitigating noise pollution have escalated. Moreover, the construction boom in emerging economies, coupled with the increasing focus on sustainable building practices, has further augmented the market in this region.

Region with highest CAGR:

North America is expected to witness profitable growth over the projection period, due to increased infrastructural development, particularly in HVAC systems across commercial and industrial sectors. The region's focus on energy efficiency, stringent noise regulations, and the demand for improved indoor air quality contribute to market expansion. Major construction activities in the United States and Canada drive the adoption of round sound attenuators. Furthermore, innovations in acoustics and ventilation technologies, coupled with a growing emphasis on green building practices, position North America as a key market for round sound attenuators, fostering competitive dynamics and technological advancements.
