On the industrial front, Euronoisecontrol - GEIE has investigated several sites affected by industrial soundproofing to determine their potential impact on the neighborhood. We have provided predictions and noise abatement guidance for roof top air conditioner units, gas turbines, chain lines, and exhaust hoods for laboratories. Euronoisecontrol - GEIE has also participated in "quiet" product development programs. Room acoustic characteristics have been improved in road tunnels and bridges, offices and at industrial sites.

Soundproofing
- INDUSTRIAL ACOUSTICS
To prevent hearing loss and produce an acceptable acoustic environment
at industrial sites, Euronoisecontrol - GEIE can assist in determining
the appropriate noise controls - whether they be administrative or involve
the selection of the proper treatments. Our engineers can assist in the
design or layout of a factory to minimize the workers' exposure, can survey
a site to determine compliance with ISO-9000 requirements, diagnose which
units and transmission paths dominate the noise, and determine the optimum
abatement techniques. These treatments must consider cooling, access,
maintenance, regulatory requirements, the nature of the noise - tonal
versus broadband, continuous versus intermittent. In once recent case,
Euronoisecontrol - GEIE has provided a passive silencer for an exhaust
system that replaced an active system. A greater noise reduction was achieved
at one-tenth the cost.
Euronoisecontrol - GEIE can has the experience and know-how needed to
address all these facets.
Soundproofing
- ENVIRONMENTAL
Site surveys can
be performed to determine the noise level at boundaries. Diagnostic tests can
be conducted to determine the primary source(s) of noise or vibrations. Resulting
noise levels can be compared to local, state, or European requirements. Euronoisecontrol
- GEIE can help evaluate whether the noise could or should be considered annoying.
Predictions can be carried out to determine if the noise radiated from stacks,
openings, or external equipment can contribute to excessive noise. For construction
sites or outdoor activities, Euronoisecontrol - GEIE can assist in determining
the noise levels resulting from the operation of various construction equipment
and supply guidance on the optimum noise control approach. Controls can be applied
to the construction equipment or by means of barriers.
Soundproofing - ARCHITECTURAL
The background
noise inside rooms, gyms, auditoriums, or studios should not interfere with
effective speech. Theaters or concert halls require the correct reverberation
time to enhance listening to music. The "room constant" can be adjusted
to achieve the correct balance of speech and music in any location. Euronoisecontrol
- GEIE can assist in determining the proper room acoustic characteristics and
advise on the materials to be used to achieve this characteristic.
Soundproofing
- TRANSPORTATION
Noise from planes,
trains, traffic can be abated to minimize its impact on the environment. As
necessary, treatments can be added to structures to increase their transmission
loss and decrease the impact from transportation noise.
Euronoisecontrol - GEIE
can evaluate whether source, path, or receiver treatments provide the optimal
abatement approach.
Soundproofing - NOISE & VIBRATION ANALYSIS
Euronoisecontrol
- GEIE uses modern tools for analysis and control of noise and vibration.
This is essential for the construction of new buildings or marine vessels that
must meet stringent noise and vibration limits. For shipboard predictions, Euronoisecontrol
- GEIE employs methods outlined in ISO-9000.
Euronoisecontrol - GEIE engineers also use advanced prediction tools,
including Finite Element (FE) and Statistical Energy Analysis (SEA) methods.
Euronoisecontrol - GEIE maintains a database of noise and vibration source
levels for various types of mechanical equipment, such as pumps, motors,
fans, diesel engines, and many others. Euronoisecontrol - GEIE has verified
many of the prediction noise models it developed by either full or model
scale tests.
Our engineers develop transfer functions for structural losses and radiation
models for various constructions and machinery casings
Soundproofing
- TREATMENT DETAIL DESIGN
Noise and
vibration treatment design details need to be provided in order to achieve the
required acoustic performance.
Euronoisecontrol - GEIE
engineers provide material specifications and potential vendors, detail areas
of coverage, supply installation guidelines and performance estimates.
Treatments are tailored to suit non-acoustic restraints and comply with regulatory
criteria. Design guidance is also provided for HVAC or piping systems to avoid
the need for add-on noise controls.
Our engineers can also perform on-site inspections of treatment installations
to ensure their effectiveness is not compromised.
Euronoisecontrol - GEIE measurement and analysis capabilities provide an excellent
foundation for the design of successful noise and vibration control treatments.
Our experience allows Euronoisecontrol - GEIE to engineer optimal and cost effective
solutions to excessive noise and vibration problems. Euronoisecontrol - GEIE’s
library includes a database on noise & vibration control treatments.
We have recommended both traditional and novel noise control treatments for
vessels of all sizes, factories, vehicles, construction sites, test labs, and
communities.
Soundproofing
- STRUCTURAL ANALYSIS
Euronoisecontrol
- GEIE uses Finite Element Analysis (FEA) software to model structures such
as large ship hulls or machinery foundations. The FEA models are used to predict
structural natural frequency to determine if a resonant condition could occur.
To assist in designing proper mount isolation systems, Euronoisecontrol - GEIE
analyzes foundation impedances by this method.
Euronoisecontrol - GEIE also employs forced harmonic analysis to predict responses
of a structure to know vibration source levels. Design modifications can be
developed to reduce vibration and stresses on the structure.
PREDICTIVE
MAINTENANCE / CONDITION MONITORING
Euronoisecontrol - GEIE's expertise in machinery vibration is the key
advantage to our noise-proofing services.
Euronoisecontrol - GEIE implements noise-proofing programs on various
levels. Our services include setting up noise-proofing programs and/or
performing the measurement surveys for you.
In setting up the noise-proofing programs, Euronoisecontrol - GEIE will
evaluate which plant equipment should be monitored and configure the noise-proofing
database to "see" the critical vibration signatures.
Euronoisecontrol - GEIE can assist in selecting the type of monitoring
equipment, from basic to sophisticated. We can help determine the frequency
of monitoring, and the level of the noise-proofing program to ensure the
system can effectively detect machinery failures.
Euronoisecontrol - GEIE can assist company employees to understand the
vibration analysis and provide training, or we can turnkey the entire
noise-proofing operation. This would include taking measurements, managing
the noise-proofing database and reporting to the client.
MACHINERY
ISOLATION DESIGN
Machinery structureborne vibration is one of the biggest sources of received
noise in factories and buildings.
One of Euronoisecontrol - GEIE’s
noise reduction approaches is to vibration isolate offending equipment.
Novel and innovative isolation designs have been developed to overcome
system restraints on space, weight, cost, and operations. To achieve optimal
reductions, Euronoisecontrol - GEIE reviews proper equipment mounting
points, isolator parameters, and performs 360-degree-of-freedom calculations.
Our empirical and analytical tools allow correlation of vibration reduction
to noise reduction.
MEASUREMENT
