is all among us and but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue. Automobiles are undeniable the greatest source of pollution. The noise pollution created by cars is immense. Another polluting effect of cars is the heat it creates. This heat makes it unpleasant to be near the car while its running. And of course the most famous of the automobiles evils is the exhaust. The toxic

Noise Pollution The nature of sound Sound‚ a manifestation of vibration‚ travels in wave patterns through solids‚ liquids and gases. The waves‚ caused by vibration of the molecules‚ follow sine functions‚ typified by the amplitude and wavelength (or frequency) Sound waves of equal amplitude with increasing frequency from top to bottom Reflecting on noise “Noise" derived from "nausea‚" meaning seasickness Noise is among the most pervasive pollutants today Noise is unavoidable for many

The actual transmission then follows‚ with further processing and filtering of noise. Finally we have reception‚ which may include processing steps such as decoding‚ storage and interpretation.

In Seneca’s essay “On Noise” the reader initially encounters a hypothetical array of distractions that the speaker has set forth in order to prove a point. In this essay‚ the speaker discusses two types of distractions: external distractions that detract from one’s senses‚ and internal distractions that detract from one’s sense of reason. The speaker goes back and forth between the distractions discussing the various effects of each type. In “On Noise” Seneca illustrates that in order for one

Figure 1.1 illustrates discrete data transmission‚ which is the transmission of one message from a finite set of messages through a communication channel. A message sender at the transmitter communicates with a message receiver. The sender selects one message from the finite set‚ and the transmitter sends a corresponding signal (or “waveform”) that represents this message through the communication channel. The receiver decides the message sent by observing the channel output. Successive transmission
