Noise can be defined as unwanted or excessive sound that can cause disturbance, discomfort, or harm to human beings and other living creatures.
Types of Noise:
- a. Continuous Noise: Continuous noise is a type of noise that occurs for a long duration without interruption. Examples of continuous noise include traffic noise, construction noise, and industrial noise.
- b. Intermittent Noise: Intermittent noise is a type of noise that occurs periodically or with breaks in between. Examples of intermittent noise include car horns, sirens, and barking dogs.
- c. Impulsive Noise: Impulsive noise is a type of noise that occurs as a sudden and brief burst of sound. Examples of impulsive noise include explosions, fireworks, and gunfire.
- d. Low-Frequency Noise: Low-frequency noise is a type of noise that has a low frequency, typically below 20 Hz. This type of noise can cause discomfort, disturbance, and even health problems, especially for those who are sensitive to it. Examples of low-frequency noise include engine noise from ships and trains, and wind turbines.
