1.what is vibration?
2.what are the hazards of noise pollution?
Answers
Answer:
1.Vibration is the mechanical oscillations of an object about an equilibrium point. The oscillations may be regular such as the motion of a pendulum or random such as the movement of a tire on a gravel road. ... Vibration enters the body from the part of the body or organ in contact with vibrating equipment.
2.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

1. The periodic back and forth motion of the particles of an elastic substance or medium is characterized as vibration.
2. Noise is a disruptive sound that is unwanted or unpleasant. The presence of numerous undesirable sounds disrupts the environment, resulting in noise pollution.
Explanation: 1. The frequency or frequencies at which an object tends to vibrate when touched, struck, plucked, strummed, or otherwise disturbed are known as the object's natural frequency.
- Everything vibrates at a natural frequency or a set of frequencies. The inherent frequencies of the sound waves created by vibrating objects determine the quality of the sound produced.
- The influence within or upon an oscillatory system that has the effect of decreasing, restricting, or preventing its oscillation occurs owing to damping force, which is defined as the influence that reduces, restricts, or prevents its oscillation.
2. Pollution of the environment is one of the most serious hazards to human health.
- Traffic, people talking on their phones for 1-2 hours, loud music, driving horns, and other issues have all become part of metropolitan life.
- Noise pollution can induce hypertension, sleeping disturbances, and even health problems due to the abundance of sounds in the surroundings.
