Characteristics of noise
What are the 5 characteristics of sound?
There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself.
What are the characteristics of noise pollution?

What are the 2 basic properties of noise?
The two most important characteristics which must be known in order to evaluate the sound or noise are it’s amplitude and frequency. The amplitude or height of the sound wave from peak to valley determines the loudness or intensity. The wave length determines the frequency, pitch or tone of the sound.
What are the classification of noise?
Classification of Noise
External noise may be classified into the following three types: Atmospheric noises. Extraterrestrial noises. Man-made noises or industrial noises.

What is noise pollution explain?
Noise pollution can be defined as any disturbing or unwanted noise that interferes or harms humans or wildlife. Although noise constantly surrounds us, noise pollution generally receives less attention than water quality and air quality issues because it cannot be seen, tasted, or smelled.
What is sound caused by?
Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.
What is the effect of noise?
However, repeated exposures to loud noise can lead to permanent tinnitus and/or hearing loss. Loud noise can create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals.
