Waterford Unified School District
The Waterford Unified School District is a K through 12 public school district in Stanislaus County, California, United States. (Waterford, 2006) As early as 1989, students attending Waterford schools were bussed if they needed to cross State Route 132 to reach school. Noise issues Sound levels at the Waterford Junior High School have been determined to be approximately 64 DbA, primarily due to roadway noise from State Route 132. This sound level is considered generally unacceptable from the standpoint of speech interference, safety and health effects Health effects (or health impacts) are changes in health resulting from exposure to a source. Health effects are an important consideration in many areas, such as hygiene, pollution studies, occupational safety and health, ( utrition and health sc ....Earth Metrics Incorporated, "Waterford Junior High School, California Environmental Quality Act, Environmental Assessment", Waterford School District, prepared for the State of ...

Full-time Equivalent
Full-time equivalent (FTE), or whole time equivalent (WTE), is a unit that indicates the workload of an employee, employed person (or student) in a way that makes workloads or class loads comparable across various contexts. FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load. United States According to the Federal government of the United States, FTE is defined by the Government Accountability Office (GAO) as the number of total hours worked divided by the maximum number of compensable hours in a full-time schedule as defined by law. For example, if the normal schedule for a quarter is defined as 411.25 hours ([35 hours per week * (52 weeks per year – 5 weeks' regulatory vacation)] / 4), then someone working 100 hours during that quarter represents 100/411.25 = 0.24 FTE.

California State Route 132
State Route 132 (SR 132) is a state highway in the U.S. state of California that connects the Central Valley with the Sierra Nevada foothills and the California Gold Country. Its western segment also connects the city of Modesto with the San Francisco Bay Area via I-580, although this route is discouraged due to it being a two-lane road between Modesto and Interstate 5 (motorists are instead encouraged to take SR 120 in Manteca to I-5 and I-205 to I-580). East of Modesto, the road climbs the foothills and eventually ends at SR 49 at Coulterville. Portions between I-580 and I-5 are a four-lane freeway, and there are plans to upgrade the portion between I-5 and SR 99 in Modesto to an expressway, with west of SR 99 currently open. Route 132 is a two-lane road important to recreational travelers en route to Modesto Reservoir, Turlock Reservoir, Don Pedro Reservoir and the Sierra Nevada foothills.

A-weighting
A-weighting is the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. A-weighting is applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies. It is employed by arithmetically adding a table of values, listed by octave or third-octave bands, to the measured sound pressure levels in dB. The resulting octave band measurements are usually added (logarithmic method) to provide a single A-weighted value describing the sound; the units are written as dB(A). Other weighting sets of values – B, C, D and now Z – are discussed below. The curves were originally defined for use at different average sound levels, but A-weighting, though originally intended only for the measurement of low-level sounds (around 40 phon), is now commonly used for ...

Roadway Noise
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. In developed and developing countries, roadway noise contributes a proportionately large share of the total societal noise pollution. In the U.S., it contributes more to environmental noise exposure than any other noise source. History Roadway noise began to be measured in a widespread manner in the 1960s, as computer modeling of this phenomenon began to become meaningful. After passage of the National Environmental Policy Act and Noise Control Act, the demand for detailed analysis soared, and decision makers began to look to acoustical scientists for answers regarding the planning of new roadways and the design of noise mitigation. Partial bans on motor vehic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise Health Effects
Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance. Changes in the immune system and birth defects have been also attributed to noise exposure. Although age-related health effects (presbycusis) occur naturally with age, in many countries the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime. Noise exposure has been known to induce noise-induced hearing loss, tinnitus, hypertension, vasoconstriction, and other cardiovascular adverse effects. Chronic noise exposure has been associated with sleep disturban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterford High School (California)
Waterford High School is a public comprehensive high school in Waterford, California, United States. Opened in 2001, it is the only high school in Waterford Unified School District. History The school began being planned after voters approved a school bond in 1994. Before Waterford High School was built, students were bussed to Hughson Union High School, Hughson, Oakdale High School (California), Oakdale, or Riverbank High School. Waterford High School opened in fall 2001. After initial low test scores, the teaching staff took on the challenge of improving the delivery of teacher-directed instruction. The motto was "student achievement rises as instruction improves." Student test scores came up 105 points in 2003. The school ranked first among Stanislaus County high schools on the index in 2006. Waterford High School earned a Title I Academic Achievement Award and was named as a California Distinguished School in 2007. Campus Waterford High is located on the southwest corner ...
