Tenor Engineering Group

What Tenor Engineering Group does

Tenor Engineering Group is a privately held acoustical engineering consulting firm headquartered in Washington State with offices in Seattle and Portland, serving clients across the Pacific Northwest. Founded by Erik Miller-Klein, PE, INCE Board Certified, the firm applies evidence-based design to building acoustics for commercial, healthcare, education, multi-family residential, government, industrial, hospitality, and worship spaces, with services spanning sound isolation, room acoustics, building systems noise and vibration control, industrial noise control, and acoustic testing (including commissioning, footfall noise, sound power, and noise code compliance).

The firm's core technical offering is See Acoustics™, a proprietary visualization service that translates acoustical testing — sound transmission, sound absorption, environmental noise, and sound power/emission — into visual artifacts accessible to design teams and building owners. This is complemented by acoustic performance commissioning, in-situ sound power measurement, photo-enabled sound intensity analysis, and field testing. The firm maintains active volunteer roles in ASHRAE, ASTM, ANSI, FGI, WELL Building Standard, and Green Building Initiative, which it uses both to influence standards and to maintain a regulatory edge in compliance-heavy engagements.

Tenor operates a sales-led, project-based B2B professional services model. Engagements originate through direct outreach, RFPs, and quote requests, with pricing structured on a custom per-project basis. Marquee clients include Apple, Google, Microsoft, Amazon, Adobe, T-Mobile, JPMorgan Chase, Kaiser Permanente, Providence, the U.S. Army Corps of Engineers, the GSA, Costco, Georgia Pacific, and Stanford University. The firm is founder-owned, with no disclosed institutional investors, parent company, or public listing.
