Appendix E Review of Effects of Aircraft Noise, Chaff, and Flares on Biological Resources

چکیده
The review of the noise effects literature shows that the most documented reaction of animals newly or infrequently exposed to low-altitude aircraft and sonic booms is the “startle effect.” Although an observer’s interpretation of the startle effect is behavioral (e.g., the animal runs in response to the sound or flinches and remains in place), it does have a physiological basis. The startle effect is a reflex; it is an autonomic reaction to loud, sudden noise (Westman and Walters 1981, Harrington and Veitch 1991). Increased heart rate and muscle flexion are the typical physiological responses.

Introduction: Persecutors of aircraft noise at an airport has a close relationship with the alternate of landing and take-off weight of the aircraft and operations planning during the night. Now aircraft that spill in Yazd airport and take-off of aircraft is of jet engines or so-turbofan mean that the resulting sound will be very high. Methods: In this descriptive, cross-sectional me...
متن کاملAdaptive Optimum Notch Filter for Periodic Noise Reduction in Digital Images
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
