My goal is to provide unique solutions for your acoustical and audiovisual needs. As a consultant I am looking for opportunities where I can assist you in solving your acoustical issues, while building a solid client relationship based on trust and high design standards.
During my career of over 40 years in acoustics and sound system design, I have provided acoustical consulting services on over 1000 projects. These projects range from sports facilities, worship spaces, and corporate board rooms to k-12 schools, high school performing arts centers, and community colleges and university facilities. You can view detailed descriptions of these project types on my company website at www.rgdlacoustics.com.
My consulting services include sound system design and specification, installation supervision, acceptance testing, and instruction. A few of my specialty areas include environmental noise work, design, measurement, and control for a wide variety of acoustical environments. I enjoy lecturing and publishing on all types of acoustical design, performance and applications.
