AGI’s
acoustical consultants have extensive experience evaluating the effects of
aircraft noise and its associated problems on surrounding communities at
several commercial and military facilities. AGI consultants have previously
provided consulting services to airport and heliport operators, government
agencies, and a number of aviation planners in the areas of aircraft noise
evaluation, environmental studies, and land use planning. The impact of aircraft
noise on surrounding communities is evaluated in a timely and economical manner
utilizing noise survey data, flight and aircraft operations information, and
our professional teams knowledge of current aircraft noise rating techniques
including sound exposure level (SEL), day-night noise level (Ldn), and
community noise equivalent level (CNEL). These services are available for
projects involving noise modeling studies, master plan updates, new site
selection, expansion alternatives analysis, AICUZ, Part 150, and land use
studies.
AGI’s
professional staff effectively utilizes their research modeling resources in
preparing airport environmental assessments and compatible airport vicinity
land use plans. AGI’s staff has extensive experience in airport noise monitoring,
computer modeling environmental assessment of airport expansion programs, and
heliport/helistop citing duties.

As
the demand for large multi-family housing or transient lodging developments
increases, there is a heightened awareness of the seriousness of space-to-space
intrusion of noise and vibration. Achieving appropriate transmission loss
characteristics of common-wall building designs becomes paramount to developers,
regulatory agencies, and residential/lodging stakeholders. AGI Consultants have
provided consulting services to architects, builders, home owners’
associations, law firms (both plaintiffs’ and defendants’ parties), and
engineering firms in the areas of project planning and design, partition
isolation evaluations, transmission loss predictions, sound and vibration
intrusion measurements, mitigation measures, and litigation support.
AGI’s
staff members have over 20 years of experience in conducting noise studies for
architects, condominiums, developers, hotels, and attorneys. Our staff’s
experience includes supervision of acoustical studies involving party wall and
floor/ceiling designs, investigation of HVAC, plumbing and mechanical noise,
and field testing of party walls and floor/ceiling assemblies (FSTC, FIIC,
NNIC, NIC, NR). Expert Witness participation in destructive tests with forensic
architects, field observations & testing, and mediation are just one
example of our services in this sector.
Our recommendations have included the repair of defects in order to meet
state standards, industry standards of care, and court decisions. We have the
expertise to technically assess each project and recognize the sensitivity to
the social, economic, legal and political influences on building acoustics
issues.

Noise and vibration studies are among
the technical services provided by AGI for the design and construction of rail
lines and rail terminals. The prediction of excessive noise levels and their
results are used to recommend noise and vibration mitigation measurements
during the design process. Methods for
reducing construction noise, such as the use of less intrusive equipment and
the benefits of topography are frequently recommended where feasibly effective
and practical. AGI staff also provides support to community involvement
programs that facilitates the identification of noise concerns at an early
stage in the project and enhance the acceptability of proposed mitigation
measures.

Analyses & Design
Vehicular noise from automobiles and
truck traffic are ever increasing. AGI’s staff is well versed in the process of
noise control. We are experts in traffic
noise analysis, modeling, community interface, noise abatement design.
Federal and state transportation noise
models have been developed and modified to predict the effect of noise on
neighboring communities. AGI staff members have extensive experience with these
models and can assist designers of transportation systems, including highways,
rapid transit terminals, and automotive tunnels, in minimizing the affect of
future traffic noise levels. AGI’s staff utilizes the latest version of the
Federal Highway Administration’s Traffic Noise Model (TNM) as well as other in
house models for predictive analyses. In conjunction with traffic flow rates,
vehicular speed, vehicle percentage mix, roadway geometry, natural sound
barriers, and other significant sound inputs, this library of computer programs
is used to provide predictions of highway-generated noise at sensitive
receptors in the project area. AGI can also generate noise contours to show
noise levels in communities adjacent to roadways. Contours can also be used to
determine environmental noise. The combination of these tools and resources
provide for effective, timely, and economical completion of surface
transportation noise projects.

AGI’s technical services include
vibration studies for the construction of roadways and rail lines.
Recommendations for vibration mitigation measures during the design process are
based on predicted vibration levels. Methods for reducing construction
vibration, including the use of less intrusive equipment, scheduling, and
construction methodology are recommended wherever their effectiveness and
practicality are feasible. AGI staff also provides support to community
involvement programs that facilitates the identification of vibration concerns
at an early stage in the project and enhance the acceptability of proposed
mitigation measures.
AGI’s staff has extensive working
knowledge of seismometers, analyzers, accelometers, and geophones. Timely field
monitoring of existing conditions and sampling of representative future
conditions for impact assessment are well within our capabilities. Our staff has a thorough understanding of
Federal and Local transportation vibration regulations and guidelines as well
as industry standards for vibration sensitive facilities.
