Abstract:
In this job a hypothesis of descriptive mathematical model is described that permits to characterize the destined areas to the conservation of the nature and the life places ("biotope"), to the aim to define the degree of existing problems, from the acoustic point of view. In agreement with European Directive 2002/49/CE (Attached I), the additional acoustic indications more adapted to the characterization of "silent zones in opened campain" have been characterized. Primary purpose of the present study is to recognize and to characterize single present sources of noise in a life place, distinguishing living natural sources from those unliving ones, and anthropic technological ones from those anthropic social ones, concentrating the attention on the definition of a weighting criterion for the produced acoustic impact from several elements of pressure that interact on a protected natural area. The data collection is in course; the result will serve to define the intervals of the acceptability classes.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...

The Cochlea
Perception of Sound Waves
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...
Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...
Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...
