Welcome to Sound Performance Engineering, LLC

Sound Performance Engineering, LLC is comprised of member engineers, associate technicians, and other associate professionals, dedicated to solving a very diverse spectrum of engineering related issues.  We are principally located in the Seattle, Washington metro area, but have worked engineering problems all over the world.

Like the issues we have solved, our engineers have very diverse backgrounds with unequalled capabilities for providing quality flight test solutions from turn-key to partial assistance in cooperation with your own professionals, but our experience and capabilities are by no means limited to aircraft related testing.

We are also able to provide other research, analysis, and testing services as well as unbiased independent research for litigation purposes with reports and/or depositions as necessitated by our clients.
