Product Sound Quality

Acentech’s RH Lyon Division encourages our clients to consider the quality of a product’s sound, not limited to its loudness but also the character of its sound. Through statistically designed jury studies, we measure the perception of the product based on its sound. We correlate that perception to those components of the product that contribute to its sound. Then we offer concrete methods to modify the sound, moving it into the realm of greater acceptability.

If a product is noisy or vibrates beyond acceptable limits, we work to ensure a quiet product by focusing on noise and vibration during the design process whenever possible. 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 called the noise audit. During the noise audit, the sources, paths and radiators of noise (and/or vibration) are identified and quantified. 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. Using engineering principles, rather than just adding absorbing material, 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.
