RWDI is proud to announce the acquisition of Wilson Ihrig, a highly respected firm specializing in acoustics and vibration consulting. With offices in the San Francisco Bay Area (HQ), Los Angeles, Seattle, and New York City, Wilson Ihrig brings a deep bench of technical expertise and a legacy of trusted client relationships to RWDI. The expertise they bring includes: transit / transportation noise & vibration, building isolation, structure-borne noise & vibration, architectural acoustics, and construction noise and vibration.

This addition strengthens RWDI’s ability to deliver nuanced, high-performance solutions in acoustics and vibration, adding to our growing portfolio of environmental and performance engineering services.

A Shared Commitment to Excellence

Since 1966, Wilson Ihrig has built its reputation on delivering analyses that go beyond the standards found in textbooks, manuals, and handbooks. Their team is known for solving complex challenges with precision and creativity, and for cultivating long-term relationships with clients who return again and again, not just for their technical excellence, but because they enjoy working with people they trust.

These values align perfectly with RWDI’s own approach: combining deep technical knowledge with a collaborative spirit to help clients achieve their goals.

What This Means for RWDI Clients:

• Expanded Expertise: Our clients now have even more access to some of North America’s most experienced acoustics and vibration specialists.
• Broader Reach: With Wilson Ihrig’s offices across key U.S. cities, RWDI’s footprint in North America is stronger than ever.
• Integrated Solutions: This partnership enhances our ability to deliver holistic, multidisciplinary solutions, whether it’s optimizing building performance, mitigating environmental impacts, or enhancing occupant comfort.

Looking Ahead

As RWDI continues to grow, we remain focused on what matters most: delivering exceptional service, innovative solutions, and trusted partnerships. Welcoming Wilson Ihrig into the RWDI family is a natural step forward in that journey.

RWDI has a long history of strategic growth and a commitment to innovation. With the addition of Newson Brown Acoustics in 2024 and now Wilson Ihrig, RWDI has firmly established itself as one of North America’s leading teams in acoustics and vibration consulting. These acquisitions build on our global momentum, following the integration of Wilkinson Murray in Australia and Southdowns Environmental Consultants in the U.K.

Together, these partnerships position RWDI as a world leader in noise, acoustics, and vibration services, serving industries ranging from entertainment and performance venues to rail and transportation, healthcare, education, and beyond.

This expansion strengthens our ability to deliver exceptional, integrated solutions that meet our clients’ evolving needs and support their broader business goals. It’s another step forward in our mission to redefine what’s possible.

We’re excited about what we can achieve together, and we look forward to continuing to serve our clients with even greater capabilities.
