Noise Noise affects many people together. In addition to the already established that. Enjoy a sound like music, then the other, there is much more that that. The Noise Caused by various mechanisms, including the engine. It is for this reason that Noise is an explanation. As a species we do not want to sound like we do not have a very wide range. The less interference Until that is harmful to health. For the general public, it can be judged subjectively oriented toward the sounds. The impact has But scholars must find a way to measure without tools. To be result-oriented, subjective, these indices nuisance of noise nuisance caused by the heaving with examples such as noise from traffic on the road. The construction area of the factory or the audio from the event. In general We explain the decibels only one not. In addition, the level is changed. Levels also vary by quite a lot of time with. It has developed indices on the basis of the volume decibels, then consider including a variation on time with the noise from the construction , we might look at that. Noise from the construction area. Make temporary outages But in areas with highly developed core could take years. Noise from the project Often the problem is strictly stressful. The impact on housing COMMERCIAL AREAS And industrial zones In residential areas Noise from construction May cause disruption to communications in the office. And other commercial environments, especially when they are open. In industrial environments Noise may be added to the existing problems more quickly. Thus increasing the risk to lose more ears. About this topic Contractors should have noticed that. Limit noise levels The edge of the construction area There should be much According to standards set by the government and the need for sound measurement. Including analysis, accurate sound with noise from road traffic , traffic seemed to be the sound source. That constitutes a nuisance as possible. And affect as many people as possible. The development of new roads and railways, it is better Expressway. It means that More people It has been affected by high noise level with the noise from the traffic is spread into most environments. And make a nuisance continued. Log houses, shopping centers, offices and other workplaces. Development indices such as the index of traffic noise. Noise pollution index To deal with the problem of noise from transport. A key aspect is common. Want to measure noise accurately. And reliable, the study found. The nuisance caused by noise from road traffic. Correlated best with the volume LA10 is a statistical value, volume one. That is 10 percent of the time limit, the volume will be higher than this value, for example, if the volume of one hour 75 LA10 means that during that hour. The volume is greater than 75 decibels for 6 minutes and less than or equal to 75 decibels in the remaining 54 minutes , we could define the statistical else like LA90 level, which in time. The volume level is 90 percent higher than the (LA90), which is comparable to the sound gradually over time aircraft noise , the growth of air transport. Makes the issue of noise from the airport. And aircraft Add fiercer Many citizens have been affected. The airport is located just off the city much. And routes The plane passed over the place, it is often said the sound of an airplane during the day may be distracting in the classroom. Night Flight May interfere with sleep So, in that it describes a nuisance. Arising from the plane I have attempted to develop an index to measure aircraft noise up to such a unit called Percy May Neuss [Perceived Noise (PN dB)] for jets PN dB is approximately equivalent dB (A) +. 13 PN dB to measure suffered. Nuisance caused by a single aircraft. If the place is near the airport. Must take into account the number and type of aircraft, with rail traffic noise from the trains that come intermittently. Determined by using an average sound level LAeq energy. Then converted to a constant volume during the period. You could say that Such volume Power packed votes During the same period, the volume of industrial noise levels in industrial areas. Creating the risk of a significant deterioration of the ear. If the sound level is long due. Doing Job Make it dangerous for the deaf hear, much less have a relationship with. Sound energy into the ear. So if Fewer Sound energy into it, it will reduce the risk. Cumulative damage to hearing due to noise from industrial plants. Change it up Criteria for the Protection of the hearing. Considering the limit of the average noise level. And the time of the hearing. As well as the amount set For noise Lets get that day. If to withstand higher volume. It's time to drop Rating Comp The industrial action Use the volume From the industrial point near the residence. Then be compared with the existing volume. First there was the factory sound in offices Sound in office bother. And fielded Communications words. This may sound like printers, office equipments. Or can be caused by external noise such as traffic and the road was level background noise background noise levels defined. The volume statistical LA90 British Standards BS 4142 which does not meet the International Organization for Standardization ISO 1996-based LA95 sound in discos the noise in discos is a problem mainly at night.
