The term "noise and vibration" refers to unwanted sounds or movements that can disrupt a person's environment, activities or peace. Noise is defined as any sound that is not wanted or needed while vibration is described as an oscillating movement of the particles of an elastic solid in contact with another solid object. Both noise and vibrations are often caused by external factors such as traffic, machinery, construction work, etc., but can also be generated internally from activities within a person's home or workplace. Noise pollution is a major concern for many people living in urban areas where loud sounds from vehicles, factories, and other sources can cause stress, sleep disturbances, hearing loss, and other health problems. Similarly, vibrations caused by heavy machinery, construction equipment, or even nearby traffic can disrupt daily activities such as reading, writing, watching TV, or having conversations. In summary, "noise and vibration" refers to unwanted sounds or movements that can negatively impact a person's environment, health, and well-being.
