Dear Friends and Clients,

I’m excited to share this announcement with you! SIA Acoustics is becoming part of a larger engineering firm, joining Robert Derector Associates Consulting Engineers. We will be adding SIA Acoustics’ acoustical design and consulting to the services offered by RDA’s engineering practice.

With SIA Acoustics joining forces with RDA, new resources will be available to current SIA Acoustic clients, and acoustical consulting services will be offered to RDA clients. As part of RDA, the SIA Acoustics team will strive to maintain the high level of attention, expertise, and constructive engagement that both SIA and RDA have always worked to achieve.

The team at RDA offers a comprehensive range of mechanical, electrical, and plumbing engineering to meet the increasingly complex challenges and goals of building design and construction. Our new ability to coordinate acoustical issues in-house with these disciplines will provide RDA’s clients with a wider range of services and better communication.

Most important, through their dedication and focus on service to their clients, RDA has earned their reputation as one of the top go-to firms in the field of engineering for 38 years. With quality engineering and acoustical design services all under one roof, SIA and RDA will work together efficiently to deliver exceptional finished projects, providing practical solutions, on schedule and budget.

To make this union official, SIA Acoustics will now be known as SIA Acoustics - A Division of RDA.

I encourage you to visit RDA’s website to learn more about the firm’s wealth of expertise, and staff of almost 150. I look forward to beginning this new chapter for myself and the SIA Acoustics team, alongside RDA’s talented team, led by partners Robert Derector, Marc Feldman, and Anthony Lonigro.

Please get in touch if we can be of help to you, or if you have any questions.

Looking forward!

Sam Berkow, Principal
SIA Acoustics - A Division of Robert Derector Associates

Design Services

  • As experienced acousticians, sound system designers, and mix/recording engineers, our consultants help determine the programmatic requirements of a project and translate them to specific design goals.
  • We work with the design team continuously from the start of the project through facility commissioning to ensure that acoustic and technical system design parameters are met.
  • We provide drawings and detailing to address space planning, room acoustics, sound isolation, HVAC noise control, and technical systems.
  • Based on modeling, prediction calculations, and analysis, we specify finish treatment types and quantities.

Consulting Services

  • We address a specific problem of an existing facility and provide a set of practical schematic recommendations.
  • The level of detail we provide is adequate to understand the issues and basic costs.
  • Does not include construction-level detail.
  • Includes follow up correspondence as needed. Our goal is to be sure this process is helpful.

Advisory Services

  • We present a list of identified issues and provide general direction for improvement in a concise document.
  • Can serve as the basis for further involvement and discussion.
  • May be used for general review of existing design (by others) with minimal investment.
  • Lowest cost and risk. If we don't think any serious issues exist, we will tell you!
