Product Noise and Sound Quality
Acentech's RH Lyon division is one of the most experienced groups of product noise specialists in the US. Whether you are designing a new product, or want to improve the sound of an existing product to make it more competitive in the marketplace, we can assist you with an array of services including:
Product Noise
"The RH Lyon Division's engineering staff helped us focus our design efforts on the areas that had the greatest impact on noise reduction. Their suggestions were easily implemented into our low cost product re-design, and their staff was truly pleasant to work with. I look forward to another opportunity to engage the RH Lyon Division."

Using engineering principles we are able to provide expert consultation in the design of a product that is quieter, operates more efficiently, and is often less costly to produce. A quiet product will be well positioned to compete in the global marketplace. This is true for consumer appliances, office equipment, medical devices, power tools, and lawn and garden equipment. For certain classes of products, the European Union is imposing increasingly strict noise standards. For other products, consumers are demanding the same. Products can be quieted by adding sound absorbing materials (at an added cost/per unit) or, more efficiently, by using engineering principles to reduce the source of the noise or vibration.
The most effective way to ensure a quiet product is to focus on noise and vibration during the design process. We can assist by providing design guidelines, analyzing design choices and evaluating and/or specifying layouts and components. With an existing product, the "quieting" process begins with a method we call the noise audit. During the noise audit, we identify and quantify the sources, paths and radiators of noise (and/or vibration). Armed with this information, we can offer cost/benefit scenarios based on the relevant noise sources. With close client interaction, and with sensitivity to manufacturability and cost/per unit, we can then implement and test these solutions. Our engineering expertise extends to heat transfer, fluid flow, and electrodynamics, giving us the breadth to design mufflers and impellers, determine heat loss, or modify noise inducing electrical circuitry.
We consult on consumer products, medical devices, power tools, office equipment, lawn/garden equipment, and more.

Product Sound Quality
- Sound source identification
- Product sound perception
- Jury studies
- Data processing and analysis
- Sound modification
- Design intervention for noisy products
Acentech’s RH Lyon Division specializes in product noise and vibration reduction, product sound quality improvement, and machine condition monitoring. We offer strengths in acoustics, vibration, active noise and vibration control, dynamics, structural design and signal processing. Our experience in noise control and quiet product design over the past 30 years has proven that a multi-disciplinary approach yields creative, successful solutions. As a project develops, the broad background of staff skills allows us to work directly with representatives from product planning and design, marketing, engineering, and other specialty areas.

Analytical Modeling and Simulation
- Process evaluation
- Acoustic simulation
- Transmission of noise and/or vibration
- Mitigation recommendations
We offer comprehensive consulting in the analytical modeling of sound and vibration generation and transmission and in the simulation of dynamical processes. We often use modeling and simulation techniques, both purely analytical as well as numerical, to evaluate the role that various mechanisms play in determining the sound and vibration characteristics of a particular device and to establish their relative importance. These techniques complement our own fundamental understanding of mechanics, dynamics, acoustics and wave propagation and our expertise in experimental design, measurements, and signal processing. Some of the numerical methods we employ for predicting sound and/or vibration response include Statistical Energy Analysis, Finite Element Analysis, Boundary Element Methods, block diagram modeling, and motion simulation.
