To our valued clients, partners, and community: for over 30 years, Patching Associates Acoustical Engineering has provided trusted expertise in acoustics, noise, and emissions management. We are proud to announce the next step in our evolution: Patching Associates is now operating as OpenCycle Technologies

This name change reflects a bold new chapter—one where we expand our capabilities beyond traditional consulting and embrace a platform-based, technology-enabled approach. OpenCycle is designed to meet the growing complexity of environmental challenges with speed, scalability, and precision.

While our name has changed, what has not changed is our commitment to you. All existing contracts, proposals, and ongoing projects remain in place, and you will continue working with the same professionals you know and trust.

We remain dedicated to technical excellence, regulatory alignment, and responsive service. Whether we are supporting you with building acoustics, energy and resources, transportation and traffic, regulatory guidance, or community engagement, you can expect the same high standards and access to our team of experts—now with enhanced tools and reach. Thank you for being part of our journey. We’re proud of our roots as Patching Associates, and we’re excited about where we’re headed as OpenCycle Technologies.
