Moving power generation on campus.
Both the National Institute of
Standards and Technology (NIST) and the Naval Station Norfolk have
recently completed design projects to increase on-site power
co-generation capabilities. The NIST campus in Gaithersburg,
Maryland, is adding a
new plant building
containing an 8 MW Solar Taurus T70 gas turbine, a Heat Recovery Steam Generator (HRSG), and ancillary system
equipment. An air-cooled fuel
gas compressor will be located outdoors in a sound attenuated enclosure. Additionally,
JMS Acoustics measured the existing daytime and nighttime sound levels, to
quantify the potential acoustical impact of the proposed combined heat and power
(CHP) plant at the
nearest adjacent residential properties, and in the vicinity of the new plant
on the NIST campus. The Naval Station Norfolk in Norfolk, Virginia, is adding
a new co-generation
plant consisting of a 15 MW Solar Titan T130 gas turbine, a Heat Recovery Steam Generator (HRSG), and ancillary system
equipment. Additionally, two
2.5 MW natural gas generators, and two 2.5 MW
diesel generators, will be installed to bring the total plant
capacity to 25 MW. An air-cooled fuel
gas compressor will be located outdoors in a sound attenuated enclosure. JMS Acoustics worked with the design
teams for both projects to provide full service acoustical
consulting for the development of comprehensive sound mitigation
measures for both sites.
Improving education through better classroom
The New Jersey School
Development Authority (NJSDA) awarded Terminal Construction the
design/build contract for the
Gloucester Elementary/Middle School in Gloucester City, NJ. JMS
Acoustics is proud to be part of the design team. The NJSDA is using
the ANSI/ASA S12.60-2010 Acoustical Performance Criteria,
Design Requirements, and Guidelines for Schools as the guideline for
the project, in addition to seeking LEED certification. As part of
the project, JMS Acoustics will be consulting on the interior
acoustics for core learning spaces, acoustical design of exterior
building envelope for sound mitigation of aircraft noise, control of
classroom mechanical system noise, and exterior community noise due

JMS Acoustics completed
measurements of the sound associated with the aeration operations at
the Pleasant Valley School District's water treatment lagoons
located at the Pleasant Valley Middle School in Brodheadsville,
Pennsylvania. J. Michael Spencer provided expert testimony in
acoustics during the trial, which contributed to the school district's successful
sees continued growth in the rental design market.
The new year has brought
continued growth in the number of rental projects currently under
design at JMS Acoustics. Exciting projects include the acoustical
design for several new open-web truss wood-framed communities, with
retail components; two mid-rise luxury rental communities; and new
modular wood-framed apartment building located near Temple University.
Additional services on these projects include the mitigation of
outdoor sound sources, sound and vibration recommendations for
mechanical and plumbing systems, and noise control for back-up
provides custom acoustical designs for new residential communities.
JMS Acoustics has assisted
numerous developers, architects and engineers with the acoustical
design of apartments, condominiums and mixed-use developments. JMS
Acoustics provides solutions for the sound isolation and impact isolation (STC and IIC) in all levels
of multi-family communities. JMS Acoustics has specific experience in sound and
impact isolation for both new and existing wood, concrete and
metal-framed projects, including open web trusses, composite metal
joists, plate concrete systems, and others. We provide the expert
guidance to select the sound and vibration design and products appropriate for
JMS Acoustics assists in selecting
locations for buildings, which reduce the noise exposure from nearby noise
sources, and reduce the cost of exterior wall sound isolation. For areas were
additional sound isolation is necessary, JMS Acoustics develops recommendations for façade
sound isolation design, including walls,
windows, and the roof, to achieve acceptable interior sound levels.
Acoustics has recently provided acoustical design and testing services for numerous
multifamily communities throughout New Jersey, Pennsylvania, New York, Connecticut,
Massachusetts and Maryland. Our Bethlehem, Pennsylvania, office consults
JMS Acoustics can meet your challenging project
needs using our unique acoustical assessment and modeling tools.
JMS Acoustics uses modern instrumentation, such as Brüel
Type 2270 portable sound level analyzer. In addition to advanced
sound pressure level measurement and analysis, the Type 2270 can be
used to perform narrow band FFT measurements, building acoustics
measurements to quantify reverberation times (RT60), sound
transmission class (STC) and
impact insulation class (IIC), and can be used for short and long duration
indoor or outdoor sound level monitoring (LDN, DNL, Leq, SEL, CNR,
etc.). When used with JMS Acoustics' Norsonics Nor277 impact tapping
machine, impact insulation class measurements (IIC) can be performed accurately and
quickly in full accordance with the ASTM testing standards.
In addition to the Type 2270 portable sound
level analyzer, JMS Acoustics has many noise dosimeters to quantify
employee noise exposure and assess your Occupational Safety and Health Administration (OSHA) or Mine Safety and Health Administration (MSHA) compliance assessment needs.
Unlike many industrial hygiene firms, we can also design the noise
control measures to lower your employees' noise exposure, resulting
in a safer and more productive work environment.
Acoustics is an independent acoustical consulting firm specializing in sound
It is a great pleasure to share the exciting news that I have left
Lewis S. Goodfriend & Associates and started my own acoustical consulting
firm, JMS Acoustics, LLC. JMS
Acoustics looks to continue and build upon the relationships forged with developers, builders, architects,
engineers and other design
professionals throughout the Northeast.
