Learning Objectives:

  1. Develop a basic understanding of acoustic metrics.
  2. Describe the general acoustic performance goals of the projects presented in this course.
  3. State one acoustical challenge and its resolution presented in this course.
  4. Explain the value of a balanced acoustical design in commercial spaces.

This course is part of the Acoustics Academy

The acoustical quality of commercial spaces is impacted by many factors, and ensuring adequate speech reception and speech intelligibility is a common challenge. In this course, you will learn about basic metrics used in acoustic design and how specific architectural and acoustic parameters can be used during the design process. Through example, you will learn about the factors that lead to increased acoustical performance and comfort in commercial projects.

Eric Lambiaso, LEED AP BD+C, Eric is a senior associate and LEED AP architectural designer in Sasaki’s interiors group with expertise in all phases of design, from programming through construction administration. With over 20 years of experience as both a project manager and project architect, Eric has led several large commercial design teams. Eric also has a passion for sustainability and is involved in environmental endeavors both within Sasaki and the larger community.

Eric holds a Bachelor of Architecture and a Bachelor of Science in Building Science from Rensselaer Polytechnic Institute. He also completed an International Design Program in Architecture at Ecoles D’Beaux Art Americaines de Fontainbleau. He has served as a member of the Programming Committee for CoreNet Global and is a member of the National Association of Office and Industrial Properties.


Benjamin Markham brings this passion for acoustics to his role as principal consultant and director of Acentech’s Architectural Acoustics group. His projects involve architectural acoustics, mechanical systems noise and vibration control, and environmental acoustics consulting for performance spaces and other commercial, residential, and civic facilities, and he has an avid interest in acoustical models and 3DListening (computer simulations of acoustic environments). He has consulted on projects related to room acoustics, sound isolation, auditorium and concert hall acoustics, music rehearsal spaces, acoustics of worship spaces, classroom and lecture hall acoustics, environmental noise control, condominium sound isolation, and other aspects of acoustical design. A LEED accredited professional, Ben is a member of the Acoustical Society of America, was awarded the Robert B. Newman Medal for Architectural Acoustics in 2002, and honored as one of Engineering News Record’s Top Young Professionals in the United States in 2019.
