She has over 16 years of project / program management and principle investigator experience involving the impacts
of noise sources on marine animals.
There is no evidence that health or health - related effects from wind turbine noise would be any different to those from other
noise sources at similar levels.
Background noise resulting from local winds and
other noise sources, was shown to contribute to increases in low frequency noise that were comparable with, or higher than contributions from the wind farm.
In addition, seat her so that her better ear is closer to you, and avoid placing her near such
noise sources in the classroom as the doorway or the heater.
These other two
main noise sources are well controlled though, aided by the previously mentioned low - rolling resistance tyres and aerodynamic shape.
Therefore people are exposed to higher levels of wind farm noise than they would expect from other new
industrial noise sources.
«We need to be much more aware of the impact that this noise might have on children,» Newman said, «and make a point of trying to turn off background television, background radio, background
noise sources for at least some of the time when we're interacting with our children, to give them the best opportunity to learn from that input.»
Such an instrument performance budget is a necessity for both identifying the variety of
noise sources currently limiting Doppler measurements, and estimating the achievable performance of next generatio... ▽ More We describe a detailed radial velocity error budget for the NASA - NSF Extreme Precision Doppler Spectrometer instrument concept NEID (NN - explore Exoplanet Investigations with Doppler spectroscopy).
The point of the «Stadium Wave» is that there is a somewhat predictable relationship
between noise sources.
As a result, strategically placed seals, barriers and insulation material are used to eliminate noise paths and insulate passengers
from noise sources.
The task of
eliminating noise sources is sure to take several months, says Lisa Barsotti of the Massachusetts Institute of Technology in Cambridge, co-chair of the LIGO - Virgo Joint Run Planning Committee.
«The challenge here is
managing noise sources that are coming from outside the protected area... however, our paper provides some really valuable information and options for managing noise and also enhancing opportunities to enjoy natural quiet.»
Here, we made the assumption of conditional independence for two reasons: (1) since our AN model had no
correlated noise source, we wished to put the decoders from the three locations on an equal footing; (2) more importantly, ignoring noise correlations rendered inference far more tractable.
It was not until almost a decade later, however, that physicist Rainer Weiss of the Massachusetts Institute of Technology calculated in detail how interferometer - based detectors would perform, given all of the
various noise sources they would have to overcome.
While military sonar systems and seismic airguns used in oil / gas exploration and scientific research have received considerable attention in the overall issue of noise impacts on marine life, less intense but far more widespread and chronically -
present noise sources, particularly large commercial ships, have only recently begun to be specifically considered.
We first generate a stellar field with planetary companions based on radial velocity discoveries, use a planetary evolution model assuming a variable fraction of heavy elements to compute the characteristics of transit events, then apply a detection criterion that includes both statistical and
red noise sources.
And according to a study, one in five US schools has poor indoor environmental quality including high temperatures and humidity, air quality with high concentrations of various pollutants, exposure to
loud noise sources, and inadequate lighting, all of which have been shown to negatively affect children's health and behaviour, and in turn, their academic performance.
These disturbances can be reduced if new schools are located away from permanent
external noise sources, and by optimising insulation in existing schools to reduce noise levels.
«School facilities should be sited and designed to isolate inside learning spaces from outdoor
transportation noise sources,» the guide says.
Aerodynamic work was conducted with both computational fluid dynamic (CFD) analysis and wind tunnel evaluation to
identify noise sources, assist designers to create appropriate design elements and prove countermeasures.
NVH performance, especially the exterior drive - by noise, is dramatically improved by using experimental methods such as Reciprocal Holography (to visualise noise reduction levels at certain frequency) and ADNA (Advanced Diagnostic Network Algorithm) to
rank noise sources in the order of their identified transfer paths.
The new acoustic package in i40 utilises materials such as air permeable carpet, sound absorbing layers for engine - room encapsulation, and textile wheel - arch liners to
absorb noise sources from engine, road, and muffler, providing a 20 % improvement in interior noise levels and a reduction in outside engine noise when idling (compared to an i40 without these features).
Dr Laurie then collects and collates pieces of information given to her by people reporting changes to their health after wind turbines and other industrial
noise sources begin operating in their vicinity, looking for similarities and patterns which give important clues as to direct causation.
The simplest is simply to scale a
known noise source, time - shift it by N months (or M years for annual data), and minimize the resulting residuals.
Be sure to place the
white noise source at a distance from the crib and ensure that it's around 50 - 60 dB (the latter is the level considered safe for nurseries in hospitals).
Expecting a person to investigate every possibility
of noise sources is not a requirement to protect a person.
What are the best white
noise sources?
«Although mitigation measures would be investigated and provided based on final site and equipment design, the addition of
the noise source at pump stations would be an unavoidable adverse impact,» Pilgrim officials wrote.
I left the original post intact, because it may still be worthwhile to eliminate the serpentine belt and pulleys as
a noise source.
Already lauded for its quiet ride, the Legacy moves another step up in cabin comfort for 2018 with further reductions from
all noise sources.
As a scientist or engineer, I wouldn't measure an electrical signal that was connected to a capacitor and
noise source.
However, the pendulum driven by the airflow is not an oscillator (assuming the swing of the pendulum doesn't change the coupling of the paddle to the airflow); it's
a noise source, with the high and low frequency components filtered out by the pendulum.
A few extracts give the flavour: «the degree of annoyance is only slightly related to noise level»; «the fact that someone was complaining was mainly determined by the personality of the individual»; «fear of
the noise source can increase annoyance»; and «adverse feelings... were influenced by feelings of lacking control, being subjected to injustice, lacking influence, and not being believed».
Responsibilities include site surveys for ventilation, air quality,
noise sources / personal dosimetry, and DOEHRS data entry.
