regular exposure to elevated sound levels that may lead to adverse effects
in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is.

What are the two types of noise?
Sound has two basic forms:
acoustic energy and mechanical energy
. Each type of sound has to be tackled in their own way. Acoustic energy or sound is what we experience every day. It is in fact vibration of air (sound waves) which is transformed by the tympanic membrane in the ear of human to audible sounds.
What are different types of noise?
All these elements factor into the pressure waves that vibrate our inner ear. Through this vibration, we hear the sensation of sound. Noises are categorized in four different ways. The things you hear throughout the day can be either a
continuous noise, intermittent noise, impulsive noise, or low frequency noise
.
