Community Sector Low Voltage and Acoustics Consulting and Design Services

Henderson Engineers offers a full suite of low voltage and acoustics consulting and design services to support a project through design and construction, as well as the full life of the building post occupancy. We have dedicated community sector staff that can provide engineered solutions, peer review, and owner representation for audio-video (AV), telecom, security, and acoustics. From project conception to our capability to sign and seal professional engineered documents, Henderson can see your project through from start to finish.

Where people gather, communication matters. Acoustical engineering helps you cut through the noise and build a space where the focus remains on the message. Our acoustics professionals set realistic sound level criteria, followed by practical sound and vibration control recommendations so you can experience your space the way it was intended. Our experts have assisted on projects across the nation.

Through collaboration with internal and external teams, he helps his clients achieve their goals through the right combination of audio-video technologies that work best for the space.

Elaina Liby
Acoustical Consultant

Elaina enjoys the diversity of community projects that she helps bring to life. Elaina reviews architectural drawings and models and gives recommendations for interior room acoustics (reverberation time and echo control) and sound isolation between vertically and horizontally adjacent spaces.

Mark Maurer
Security Technical Manager

For more than 40 years, Mark has helped transform the way we look at electronic physical security systems for sports venues, correctional facilities, educational facilities, and other structures nationwide. As an associate and professional engineer, his decades of electrical construction and engineering experience afford him unmatched insight when assisting end users to determine their physical electronic security system needs. Overall, Mark strives to design systems that are non-proprietary, reliable, intuitive to operate, and relatively easy to maintain.

Jim is committed to providing clients with the best possible design solutions. With nearly two decades of experience in the audio-video profession, he is a great asset to the team. He has worked on a variety of projects within the community sector and venue sector including K12, civic buildings and transportation and knows what it takes to make the audio-video systems in these buildings work.

Rebecca Rothermich
Telecom Technical Manager

Rebecca designs the telecommunications infrastructure that will connect all the different systems in the building. In addition to her vast experience with project types in our community sector, she’s also completed low voltage services for several venue and business sector projects.
