Noise Pollution Noise pollution is not a necessary price to pay for living in an industrial society. Much can be done to reduce the severity of the problem. For example‚ vehicles and other machines can be built to produce less noise. Four-cycle engines can replace much noisier two-cycle engines in such products as lawnmowers‚ motorboats‚ and jet skis. Labels that indicate the noise levels of appliances and tools can help consumers avoid noisy products and choose quieter alternatives. Even

Abstract. Traffic related noise pollution accounts for nearly two-third of the total noise pollution in an urban area. Noise‚ a by product of urbanization‚ industrialization and motorization‚ is increasingly recognized as an environmental nuisance that effects human health and wellbeing. Traffic noise on existing urban road- ways lowers the quality of life and property values for persons residing near these urban corridors Surat is now the tenth largest city of India having an estimated population

Noise Barriers By: Daniel Dick In the studio‚ in any live performance‚ basically anywhere music is being played‚ how the music sounds is the most important thing. Sure‚ the way they artists are dressed might be cool to see‚ and sure‚ the way they strut around stage might grab your attention‚ but the way they sound is definitely the most important component of the performance or recording. Part of the sound that they produce that is so essential to artists is the noise barrier that they use

Psychological noise is mental interference that prevents you from listening. If your mind is wandering when someone is speaking to you‚ the noise in your head is preventing communication. This is due to things like day dreaming. This was perhaps‚ what happened to me a few days ago. I was in the English class all lost in thinking of my home. I had my sister’s marriage in my home country and I suddenly started thinking of what is to be happening in my sister’s marriage. I was even very depressed because

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

UNDERSTANDING NOISE POLLUTION Most of us are very used to the sounds we hear in everyday life. Loud music‚ the television‚ people talking on their phone‚ the traffic and even pets barking in the middle of the night. All of these have become a part of the urban culture and rarely disturb us. However‚ when the sound of the television keeps you from sleeping all night or the traffic starts to give you a headache‚ it stops becoming just noise and start turning into noise pollution. For many of us
