Single Carrot Theatre, Baltimore, MD
Client: Seawall Development
Contractor: Hencken & Gaines
When the Carrots first occupied their space there were some acoustical issues due to the budget constraints most small theatre companies face.
Featured Service: Sound Insulation Acoustical Imaging
Of particular concern was the partition demising the Rehearsal Studio and the main Theater. The partition as-built was not performing as expected even after remedial sound isolation measures were carried out.
Bay Acoustics provided extensive acoustical imaging to identify sound flanking for the sound rated. Acoustical imaging analysis is a relatively new technology allowing a full 360-degree overview sound field map of the partitions and floor/ceiling assemblies without making any assumptions about the sound field. Data is acquired by scanning a disc along the partition or assembly. The disc has hundreds of microphones and cameras distributed on the surface allowing a full sound map. Noise sources are mapped by differentiating sound levels based upon the direction from which they originate. The method is very quick, allowing a full map to be calculated from a single-shot measurement and very useful in isolating individual noise sources, deficiencies through penetrations like outlets, missing insulation, structural issues, unsealed windows, etc.
Featured Service: Remedial Noise Control Roof Top HVAC Units (RTU’s)
We performed noise testing and modelling of the mechanical systems and provided recommendations to reduce the noise from rooftop mounted equipment in the Rehearsal Hall and Main Theatre.
Both RTU’s serving the most critical spaces were mounted directly above the spaces with no ceiling. Levels were measured as high as NC-60, 35 points over the recommended level. Bay Acoustics carried out extensive computer modeling of the systems and provided recommendations for sound reducing plenums, ductwork and silencers that significantly reduced the noise.
