Some of its major causes are vehicles, aircraft, industrial machines, loudspeakers, crackers, etc. Some other appliances also contribute to noise pollution like television, transistor, radio, etc. when used at high volume.

Noise pollution can come from a variety of sources, but three of the most damaging sources come from: Industrial Machinery. Vehicles. Commercial Construction Projects.

Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.

Noise pollution can be defined as any disturbing or unwanted noise that interferes or harms humans or wildlife. Noise pollution has a negative impact on wildlife species by reducing habitat quality, increasing stress levels, and masking other sounds. …

CAUSES OF NOISE POLLUTION

• Traffic noise.
• Air traffic noise.
• Construction sites.
• Catering and night life.
• Animals.
• Physical.
• Psychological.
• Sleep and behavioural disorders.

Exposure to prolonged or excessive noise has been shown to cause a range of health problems ranging from stress, poor concentration, productivity losses in the workplace, and communication difficulties and fatigue from lack of sleep, to more serious issues such as cardiovascular disease, cognitive impairment, tinnitus …

What are the common types of environmental noise?

Things to Do if You live in a Noisy Environment

1. You can go and speak with your neighbors, and ask them to be a little quiet.
2. You can also visualize yourself living in a quiet and happy environment.
3. There must be times during the day or night that are quieter.

These six entrepreneurs share their tried-and-true tactics for staying focused no matter where they are — or how loud the volume.

1. Tune out distractions.
2. Practice meditation in a noisy environment.
3. Pair over-ear headphones with music.
4. Move to an area with constant, rather than intermittent, noise.

Noise creates distortions of the message and prevents it from being understood the way it was intended. Comprehension usually deteriorates when there is loud, intrusive noise which interferes with the communication assimilation process.

If sounds are loud, they move the fluid in the inner ear more, and that can damage the hair cells. Hair cells that are damaged by loud sounds do not send signals to the brain as well as they should.

A noisy person or thing makes a lot of loud or unpleasant noise. A noisy place is full of a lot of loud or unpleasant noise. …

Noise is a loud or unpleasant sound. A noise is a sound that someone or something makes. Sir Gerald made a small noise in his throat. birdsong and other animal noises.

A cacophony is a mishmash of unpleasant sounds, often at loud volume.

Krakatoa

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

We are exposed daily to 50–60 Hz ELF-EMFs produced by most electrical home appliances [1, 2]. Several epidemiological studies have suggested that ELF-EMF increases the risk of developing cancer, including leukemia, brain, and breast cancers [3–5].

The current flowing through a high resistance such as the human body is therefore about twice the number of milliAmps at 230 Volts than at 115 Volts. This dependence on current strength which, in its turn is determined by the voltage available makes 230 Volt lines at 50 Hz more dangerous than 120 Volts at 60 Hz.

60Hz

The primary difference between 50 Hz (Hertz) and 60 Hz (Hertz) is simply that 60 Hz is 20% higher in frequency. Lower the frequency, speed of induction motor and generator will be lower. For example with 50 Hz, generator will be running at 3,000 RPM against 3,600 RPM with 60 Hz.

It will run with following problems for a 50Hz motor running on 60Hz: The core loss will increase and cause over heating of core. As the core loss will increase, the Power Factor of motor will reduce. The motor speed will be higher, so shaft load will increase.

This is because impedance of 50Hz machines increases if operate in 60Hz supply which also lowers the running ampere, while if 60Hz machine run in 50Hz power system will experience increase in running ampere & overheating that will result to reduced life expectancy of the equipment.

For a generic answer: yes you can, IF: you reduce the voltage by 50/60, the equipment doesn’t care, you don’t care about potentially overheating the motor, the process/load can tolerate the lower speed/torque, etc.

There is little real difference between 50 Hertz and 60 Hertz systems, as long as the equipment is designed appropriately for the frequency. The more significant difference is that 60Hz systems usually use 110V (120V) or thereabouts for the domestic power supply, while 50Hz systems tend to use 220V, 230V etc.

No. In fact you can not even connect two 230 V 50Hz together unless they are in phase synchronisation. Try connecting two phases of a three phase supply together to power a common load and see what happens.

230 to 220 will not hurt the machine at all. If the welder’s plug matches the outlet you should be fine. Receptacle configuration indicates amperage as well as voltage.
