Acoustic Insulation

Protect against noise and extra acoustic energy

Quick Request

Consumers want to use quiet devices that do not make unwanted or unintentional sounds. Engine or motor sounds, squeaks or rattles from vibrating components, power generation, compressors, leaking air and other environmental factors create unintentional noise that decrease customers’ perception of quality, reliability, functionality and overall satisfaction with a device. To proactively manage and improve unwanted acoustics, it is ideal to engage acoustic damping and absorption engineers early in your design phase. Early acoustic intervention allows Boyd’s engineers to predict, test, and address optimal acoustic solutions most efficiently and effectively. We can also analyze existing or late cycle designs to solve unwanted noise challenges with fix-it parts, often by adding acoustic insulation to a product to absorb or block the transmission of sound waves. Fix-it acoustic insulative solutions can act as a barrier for noise, dampen vibration to reduce excessive resonant behavior, absorb noise before it reaches the user, or isolate the source of unwanted noise before it can propagate to other areas of a device. Boyd Corporation has expert acoustic damping and treatment engineers with years of experience designing noise, vibration and harshness solutions for the most demanding, sensitive end device applications that heavily rely on quiet, stable, controlled performance.
