Meyer Sound Presents Three Technical Papers on Active Acoustics at Montreal ICA

At the 21st International Congress on Acoustics (ICA) in Montreal, Meyer

Sound led three technical paper presentations focusing on the latest

advances and applications of active acoustics, a field that has garnered
widespread interest amongst multipurpose venues and the acoustics community.

All three papers are publicly available on the Acoustical Society of America

"Optimizing Acoustics for Spoken Word Using Active Acoustics" was
co-authored by Steve Ellison, Meyer Sound's applications director for
digital products, and Pierre Germain, senior acoustic engineer. The paper
discusses the theoretical and practical issues involved in designing room
acoustics for optimum intelligibility across various uses, and describes an
active acoustic system capable of optimizing early reflections in different
scenarios. Download the full paper here:

In addition, "Electronically Variable Room Acoustics-Motivations and
Challenges" was written and presented by K. Anthony Hoover, FASA, principal
at McKay Conant Hoover Inc. in Westlake Village, Calif., and Ellison. The
authors presented a case study including both passive and active acoustic
treatment for a proposed renovation of the Santa Monica Civic Auditorium
that would enable the historic preservation of the venue while supporting a
wide range of uses, including conferences, rock and pop shows, and
orchestral performances. Download the full paper here:

Lastly, Roger Schwenke, Ph.D., staff scientist at Meyer Sound, presented his
paper at ICA entitled "Active Acoustics and Sound Reinforcement at TUI
Operettenhaus, Hamburg." Schwenke's case study examines the unique
integration of active acoustics and sound reinforcement system design in a
theatrical space. This combination allows the same system components to be
utilized for both extension of room reverberation and creative applications
of spatial surround effects. Download the full paper here:

The 2013 ICA was held in June at Montreal's Palais des congrès jointly with
the 165th meeting of the Acoustical Society of America and the 52nd Meeting
of the Canadian Acoustical Association.

In addition to the ICA conference, Schwenke and Ellison also presented their
paper "Active Acoustics in Physically Variable Spaces" at the International
Symposium on Room Acoustics in Toronto, a satellite conference of the ICA.

The paper offers an overview of venues that use active acoustic systems as
they alter room size or arrangement through subdivisions or other methods.

The paper is available in the proceedings document of the conference.
Meyer Sound officially launched its active acoustic system, Constellation®,
in 2006. Since then, Constellation has been installed in more than 50 sites
worldwide, including performing arts centers, concert halls, universities,
secondary schools, houses of worship, conference facilities, theatres, and
entertainment spectacles.

Family owned and operated since 1979, Meyer Sound Laboratories, Inc. designs
and manufactures high-quality, self-powered sound reinforcement
loudspeakers, digital audio systems, active acoustic systems, cinema sound
systems, and sound measurement tools for the professional audio industry.
