SOUND MODELING & STUDIES

At Metropolitan Acoustics, we are experts in acoustic simulation software. One of the tools we use is EASE (Enhanced Acoustic Simulator for Engineers) to accurately depict the sound characteristics of auditoriums, concert venues, ballrooms, outdoor theaters, or any space where acoustics and audio are important. We can simulate both amplified and non-amplified sound and accurately predict the sound system coverage, reverberation, and various types of echo that will occur depending upon the characteristics of the room and the materials chosen to address the acoustics of the particular space.

The animation below shows the sound pressure levels (SPL) at 800 Hz from the loudspeaker arrays as it propagates throughout a uniquely shaped performance venue. As the SPL turns gray, it is inconsequential to the sound under the canopy. The important items to note are the surfaces that the sound hits when it is magenta, red, light blue or light green. These are the areas which will require sound-absorptive materials to correct the unsatisfactory acoustics in the arena.

Sound modeling allows us to accurately design the most effective combinations of acoustic treatment in the space in combination with individual loudspeaker type and placement. Software like EASE saves time and money by allowing accurate and proven troubleshooting before construction begins and before the real audio system is installed on site.

For outdoor venues, our modeling capabilities will determine the amount of sound energy at the property lines of the venue. This is important for outdoor theaters that are close to residential properties. We can work with the design team to reduce propagation of sound into the neighborhoods.

For existing spaces with sound issues, our team has the latest in measurement instrumentation and can assess the acoustics and sound systems in rooms with sound issues including speech intelligibility problems, hot spots and dead spots, and lackluster sounding music. We conduct testing, audition the systems, and provide feedback as to the current state of the room, desired goals for improvement, and steps to get to those goals.
