1. Turnoffyourelectronics. Computers, game systems, televisions and the like all make noise when they’re not in use—whether it’s a fan spinning or that high-pitched, barely-audible screech some TVs make in standby. Over time, all of these sounds cause stress on the ears. Turn them off when you are not using them. A little extra effort is worth it; as a bonus, you’ll save some money on electricity.
2. Soundproofyourspace. There are a lot of things you can do to reduce the sound at home (or perhaps your workplace).
If you have hard floors, rugs will go a long way in the fight to dampen sound.
Windows are a known weak point in many structures. Installing better windows, sealing window frames, or hanging curtains (even thin ones) will help reduce the sound coming from outside.
If you have noisy neighbors on one side of you, put furniture or a big bookshelf (preferably full of books) against that wall.
If you have laundry machines in a separate room, shut the door. Also try running appliances like dishwashers and bread machines when you’re getting ready to leave the house for a bit. When you’re gone they can make as much noise as they want.
3. Maskorcancelyournoise. Several options are available for you here. Some people like to create peaceful sounds around them. You can do this by hanging wind chimes, turning on a fan, or running a small water feature. It may seem paradoxical because you’re creating more noise, however these things help mask the more unpleasant sounds that may otherwise bother you.
People who really need help tuning sounds out could opt for a white noise machine. White noise consists of sounds of all audible frequencies (the same way white light is a combination of all visible wavelengths). White noise is able to effectively mask most outside sounds. Many people who use such machines frequently report ‘not hearing anything at all’ including the noise machine.
“Noise canceling” devices are also available. These devices use a microphone to intercept incoming sounds. Then they send out “anti-noise” signals to cancel the noise. Noise canceling headphones or smartphone apps are among the cheaper noise canceling options. Hearing aid type devices are also available, but are much more expensive
4. Earplugs. Sometimes the simplest solutions are the most effective. If nighttime noise keeps you awake, earplugs could be your ticket to sweet slumber. Just make sure you set your alarm loud enough. Earplugs can also be great if you are going to a noisy event or concert. They don’t block out all the noise; rather, they bring sounds down to a manageable level.
5. Move. This one sounds drastic, but it may be worth it. Sometimes barrier walls and thick curtains can only do so much (and we’re not about to line our walls with egg carton foam). While moving outside the city (or perhaps suburbs) will reduce your sound levels greatly, it is not possible for everyone. However, be aware that sound levels can vary quite a bit even within a city. You may not have to move very far to experience a significant drop in noise. Choosing a home away from aircraft paths, trains, highways, or industrial districts is your best bet. Several cities (such as San Francisco) have even published noise maps showing which streets and areas are the loudest.

5 Ways to Reduce Noise Pollution
1. Turn off your electronics. Computers, game systems, televisions and the like all make noise when they’re not in use—whether it’s a fan spinning or that high-pitched, barely-audible screech some TVs make in standby. Over time, all of these sounds cause stress on the ears. Turn them off when you are not using them. A little extra effort is worth it; as a bonus, you’ll save some money on electricity.

Answer:
1. identify the sound sources
vibrating sources and aerodynamic flow.
2.identify the path of the noise from the
source to the worker.
3.determine the sound level of each source.
4.identify solutions by taking into consideration
the degree of sound attenuation,operation and
productivity restraints and cost.
5.know the acceptable exposure limits identified in the health and safety legislation and quantify the necessary sound reduction
