Acoustics in Aerospace Engineering

Aero-acoustics is becoming increasingly important in the aerospace industry due to the growing concern over the noise generated by various engineering applications, such as propellers, rotors, aircraft engines, and nozzles. This is particularly important in urban and suburban areas where aircraft noise can be a significant source of disturbance and can negatively impact the quality of life for people living near airports.

Aero-acoustics involves the study of the generation, propagation, and radiation of sound in the context of aerodynamic flows. It is used to analyze and optimize the design of aerospace vehicles to reduce noise levels and improve their acoustic performance.

Aero-acoustic simulations can be used to predict the noise generated by different components of an aircraft, such as engines and propellers, and to evaluate the effectiveness of different noise reduction strategies. These simulations can also help engineers to identify potential noise problems early in the design process and make changes to reduce noise levels before a physical prototype is built.

At the same time, aero-acoustics is essential for ensuring that aerospace vehicles meet regulatory noise standards and regulations. For example, the Federal Aviation Administration (FAA) in the United States sets noise standards for aircraft operations, and aero-acoustics simulations can be used to demonstrate compliance with these standards.

Our cutting-edge Artificial Intelligence & Machine Learning integrated development solutions combine technical excellence with business insight to deliver exceptional digital experiences.

We leverage modern frameworks with CFD & FEA solvers and cloud infrastructure to build applications that scale seamlessly with your industrial needs.

Acoustics in Automotive Industry

The noise generated by turbulent flows can come from various sources, including air conditioning systems, rotating fans, and other devices that create turbulence in the airflow.

In order to design quiet car interiors, it's important to understand the sound generation and propagation mechanisms that occur when air flows over and around various surfaces inside the car.

Aeroacoustics simulations can be used to analyze and optimize the design of car interiors, including the shape and positioning of various components, such as the seats, dashboard, and air conditioning ducts. By using advanced numerical methods and acoustic solvers, engineers can accurately predict noise levels and identify potential noise problems early in the design process, allowing for design changes to be made to reduce noise levels and improve the overall acoustic performance of the car.

NVH for Hybrid & Electric Vehicles

Our engineers provide solutions to optimize electric motor noise behavior while leaving electromagnetic performance unchanged. This involves analyzing the acoustic and vibration behavior of the motor, identifying the sources of unwanted noise and vibration, and implementing design modifications to mitigate these issues.

In addition, our engineers can help integrate electric power sources in the driveline while ensuring smooth operation with minimum NVH impact. This may involve analyzing the vibration behavior of the powertrain, optimizing the design of components such as bearings and dampers, and implementing control strategies to reduce NVH levels.

Our computational tools and services can also help balance NVH and ride comfort with body weight. This involves evaluating the NVH performance of different design options, optimizing the design of components and systems to reduce NVH levels, and balancing the trade-offs between NVH and other performance factors such as weight and ride comfort.

Shipbuilding Noise Engineering

Accurate noise prediction models are crucial for designing marine applications that meet customer expectations for on-board noise levels. Whether it's a large cruise ship or a small yacht, noise is a critical factor that must be addressed during the design phase.

Exterior noise generated by propellers, hull radiation, or mufflers can be a major challenge for marine applications. This noise must be limited for discretion or environmental reasons. Designers must use advanced modeling and simulation tools to accurately predict the exterior noise levels and identify design modifications to reduce noise levels.

Interior noise is also a major concern for crew and passenger comfort. The interior noise is typically a result of engine and machinery noise, as well as noise from water and air flow around the hull. The interior noise levels must be controlled to ensure a comfortable environment for the crew and passengers.

We use advanced modeling and simulation tools to predict noise levels for different operating conditions and identify design modifications to reduce noise levels. Our engineers can also design noise control solutions to address interior noise challenges, including noise barriers, damping materials, and noise-cancelling technologies.

Audio & Consumer Electronic Device Design

The engineering process of audio devices is unique because the complete audio system must be tested, taking into account various factors such as the acoustic properties of the surrounding environment, vibration and resonance of components, and the overall sound quality. This is particularly true for audio systems installed in cars, where the acoustic properties of the car interior can significantly affect the sound quality and engineers need to consider the complete system and take into account the acoustic properties of the car interior, as well as the interaction between different components. For example, the placement of the loudspeaker in the car door and the acoustic cavity behind the loudspeaker can significantly affect the sound quality.

To mitigate these problems and reduce the number of physical tests, engineers in the audio industry are increasingly turning to acoustic simulation. By using advanced acoustic simulation tools, our engineers can accurately predict the acoustic performance of different components and the complete system, including the effects of vibration, resonance, and the acoustic properties of the car interior. Acoustic simulation can be used to optimize the design of audio systems, including the placement and orientation of different components, to achieve the desired sound quality and reduce noise and vibration levels.
