We’re on a mission.

Erik Miller-Klein, PE, INCE Board Certified, started Tenor Engineering Group to bring evidence-based design to your project’s acoustical performance goals. We envision a collaborative design process that utilizes the science of acoustic design to achieve measurable high-performance results. Our team strives to be a leader in educating the design community on the applied science of acoustics to empower designers, contractors, and users to really “hear” their space. Tenor’s team of engineers leverages research to optimize noise and vibration control solutions for your building and occupants. We volunteer to assist in the writing and development for standards organizations such as ASHRAE, ASTM, ANSI, FGI, WELL Building, and Green Building Initiative. Tenor is ready to elevate acoustic design to fit your needs.

Hospitality projects are judged by each guest and the acoustic performance’s impact on patrons’ ability to sleep can impact the bottom line.

We work with national chains and boutique proprietors on new facilities and the remediation of existing buildings/issues. Our team will review your performance specifications and your facility goals to develop a holistic acoustic design or remediation plan for your facility. This often includes a review of environmental noise from traffic and airports, noise and vibration impacts from fitness facilities, sound isolation between rooms, and optimizing the function of amenity spaces.

Worship spaces seek to connect people to connect a larger community through spoken word and music.

These spaces can be some of the most challenging for acoustical design because they require a careful balance for both speech and music. Developing a plan that respects the acoustical needs of the community, the history of the faith community and their aesthetic vision requires collaboration to develop a unified solution that balances these elements
