45dB Acoustics is Now Part of MD Acoustics

In the summer of 2026, 45dB Acoustics joined MD Acoustics, a full-service acoustical engineering firm founded by Mike Dickerson in 2012. MD Acoustics has grown to a team of more than 30 professionals holding INCE, ASME, ASA, and LEED AP credentials, with a track record of over 3,200 completed acoustical, air quality, and design projects, including a longstanding presence right here in Central California through our Los Angeles office and team members already living and working across the region. That means the Central Coast clients 45dB has always served now have a much larger team, deeper technical resources, and broader in-house testing capabilities behind every project, without losing the personal, responsive approach this practice was built on.

I was in the almost-completed Sixmilebridge Winery tasting room yesterday and the acoustics were wonderful. The sound attenuation details you designed work and look great.

Noise Management

Beyond Prescriptive Requirements

At 45dB Acoustics, we go beyond prescriptive requirements. Our Compliant/Better/Best recommendations ensure your project meets all applicable codes and requirements, allowing you to make an informed decision through actionable advice. We determine the minimum Sound Transmission Class (STC) needed for various building components by analyzing each component and each room for a tailored result.

“Do it nice, or do it twice!” Acoustics may be overlooked or priced out of initial designs, but this is to the detriment of the project and everyone who will utilize the space. Fixing bad acoustics after completing construction costs many more times what it would have initially.
