Helping Our Clients Hear the Value of Acoustics

The value of sound is difficult to see but not difficult to hear. Our acoustical specialists utilize innovative modeling techniques to aid in the design of building structures and allow clients to hear a space before it is constructed. Enhanced Acoustic Simulator for Engineers (EASE) is a software platform that incorporates the size, shape, finishes, furnishings and audio system in a space to create 3-D models of rooms.

Using EASE, our acousticians evaluate the acoustical performance of a space such as reverberation, sound pressure level and intelligibility for comparison with applicable building standards and project requirements. EASE can also produce audio simulations, or auralizations, allowing the client to hear how changing elements in a room will be heard by audiences in the space. HDR acoustical specialists used the EASE platform to model hundreds of spaces on a variety of projects.

The P114 Walter Reed National Military Medical Center (WRNMMC) Addition/Alteration project in Bethesda, Maryland, included acoustical design of an auditorium, chapel, broadcast studio, MRI suite and hundreds of medical spaces and offices. The new WRNMMC Memorial Auditorium will be used for live broadcast of conferences, naval award ceremonies and cinema.

Using EASE, Gina Jarta placed and aimed acoustical reflectors over the stage area to reflect sound from the stage to audience areas and increase speech intelligibility. Gina also optimized room shape and finishes during the design phase to create a multipurpose space. EASE modeling isn’t just for performance spaces. Madeline Davidson recently utilized EASE to simulate the acoustics of dayrooms in the Franklin County Correction Facility. Good acoustics help to facilitate communication within the space, control inmate noise and increase speech intelligibility at the guard station that is located within the room.
