For a noise burdened urban district, surrounded by road and rail traffic, the traffic noise as well as the annoyance has been measured. The size of the district is approximately one square km. With the help of 35 microphones, applied in a scalable sensor network, the .

Additional Physical Format: Online version: Effects of time-varying noise annoyance, a review. Washington, DC: U.S. Dept. of Commerce, National Bureau of Standards. Sound annoyance is a subjective matter and cannot be covered by law.
In the Netherlands the government set up laws to protect households and other noise-sensitive buildings like hospitals and schools from noise pollution. Annoyance is particularly focused on, which is considered to Effects of time-varying noise annoyance one of the first and most widespread reactions to environmental noise.
The nonauditory effects of noise on humans Effects of time-varying noise annoyance viewed as being generally stress-related, following observations that noise exposures engender physiological reactions typical to those of by: This paper addresses the negative effects resulting from the exposure to road traffic noise on people's well being with a focus on annoyance.
Following the observations that noise exposures engender physiological reactions typical of stress, the non-auditory effects of noise on humans are generally viewed as being stress-related, and annoyance is one of the first and most direct.
The effects of some temporal factors of nonsteady noise on annoyance was investigated by means of six experiments. The factors are rising speed. Introduction. The number Effects of time-varying noise annoyance complaints Effects of time-varying noise annoyance to environmental noise issues has gradually increased in recent years because the acoustic environment is a critical environmental factor affecting quality of e Effects of time-varying noise annoyance of environmental noise on physical and health include hearing impairment, various physiological effects (e.g., stress, cardiovascular effects, and Cited by: Short-term annoyance reactions to stationary and time-varying wind turbine and road traffic noise: A laboratory study Article in The Journal of Effects of time-varying noise annoyance Acoustical Society of America (5) “A theory-based model for estimating the prevalence of annoyance with aircraft noise exposure.” J.

Sound pressure level is crucial to annoyance (e.g., [5,6]) and, accordingly, the major variable in environmental noise impact assessment (e.g., [2,7]).Moreover, studies on the association of annoyance with spectral shape revealed that both low [8,9] and mid a review book high frequencies  may be r, studies comparing the effects of mid and high frequencies with those of Cited by: 4.
It may also cause annoyance, hearing damage, and other physiological problems. Although it is possible to study these effects on people on an average or statistical basis, all the stated effects of noise on people vary greatly with the individual. Several noise scales and rating methods are used to quantify the effects of noise on people.

These scales and methods consider such factors as loudness, duration, time of occurrence, and changes in noise level with time.
The effects of sound don’t stop with the ears. Nonauditory effects of noise exposure a review book those effects that don’t cause hearing loss but still can be measured, such as elevated blood pressure, loss of sleep, increased heart rate, cardiovascular constriction, labored breathing, and changes in brain by: Overall noise.
Knopper and Ollson reviewed a number of studies that examined the noise levels produced by wind turbines, perception of wind turbine noise, and/or responses to wind turbine noise [e.g., (4, 5, 10, 12, 13, 15–18, 21)].The results of more recent studies that investigated wind turbine noise with respect to potential human health effects are summarized Cited by: Quantitative information on the effects of airborne noise on people is well-documented.
If sufficiently loud, noise may interfere with human activities such as sleep, speech communication, and tasks requiring concentration or coordination. It may also cause annoyance, hearing damage, and other physiological problems. A laboratory study was designed in which the annoyance was investigated for 14 different impulse sound types produced by various firearms ranging in caliber from to mm.
Sixteen subjects rated the annoyance for the simulated conditions of (1) being outdoors, and (2) being indoors with the windows closed. In the latter case, a representative outdoor-to-indoor Cited by: 5.

It is defined in NZS as the time-average [i.e. energy-average] sound level over a hour period from midnight to midnight, with the addition of 10 dB to night-time levels, to take account of increased annoyance caused by noise at night.

Panel studies are an efficient means to assess short-term effects of air pollution and other time-varying environmental exposures. Repeated examinations of volunteers allow for an in-depth analysis of physiological responses supporting the biological interpretation of environmental impacts.

Noise exposure relates directly to Directive /49/EC and is also in line with environmental legislation in other fields. Noise exposure limits should be based on Lden contours, also advocated in the same Directive.
The objectives were: (1) determine the effects of tonal content on annoyance; and (2) compare annoyance to advanced turboprop aircraft with annoyance to conventional turboprop and jet aircraft.

McCurdy. Chapter Noise A. INTRODUCTION and annoyance, the decibel measurement is weighted to account for those frequencies most audible to the human ear. This is known as the A-weighted sound level, or “dBA,” and it is the the same sound energy as the actual time-varying sound.

Noise can be generated by fixed facilities, referred to as “stationary sources,” and by moving sources, such as vehicular traffic, referred to as “mobile sources.”. Chapter Noise A. INTRODUCTION The project site is located in a public park bordered by highways, and rail lines to the north.
When event conditions are underway, it generates crowd activity and traffic that may typically be noisy.

Several noise scales and rating methods are used to quantify the effects of noise on people. These scales and methods consider such factors as loudness, duration, time of occurrence, and changes in noise level with time.
However, it must be remembered that all the stated effects of noise on people vary greatly with each individual. The primary effects of workplace noise exposure include noise-induced temporary threshold shift, noise-induced permanent threshold shift, acoustic trauma, and tinnitus.
A noise-induced temporary threshold shift is a short-term decrease in hearing sensitivity that displays as a downward shift in the audiogram output. Page 2 of 7 Inter-noise Page 2 of 7 Inter-noise specific loudness (block N’ in Figure 1).
For time-varying sounds, the nonlinear decay of the human hearing system has to be modeled in detail. Furthermore, effects of the temporal summation and forward-masking must be taken into account (block NL in Figure 1).File Size: KB.
This paper investigates noise annoyance from wind turbines of different sizes and in different acoustic surroundings. A listening test was conducted where wind turbine noises were rated alone and together with background sounds from a deciduous forest, a busy city and road traffic.
It may also cause annoyance, hearing damage, and other physiological problems. Several noise scales and rating methods are used to quantify the effects of noise on people. These scales and methods consider such factors as loudness, duration, time of occurrence, and changes in noise level with time.
However, all the stated effects of noise on. Annoyance, effects on work performance or sleep and relaxation, and nonauditory effects may be equally important to noise control. Annoyance in particular is influenced by intervening (moderator or conditioning) variables about as much as by the physical characteristics of the noise.

Sound varies with distance. For example, highway traffic 50 feet away from a receptor (such as a person listening to the noise) typically produces sound levels of approximately 70 dBA.
