Unlike the Paleolithic, when more than one human species existed, only one human species (Homo sapiens sapiens) reached the Neolithic. The term Neolithic derives from the Greek Î½ÎµÎ¿Î»Î¹Î¸Î¹ÎºÏÏ, neolithikos, from Î½Î­Î¿Ï neos, new + Î»Î¯Î¸Î¿Ï lithos, stone, literally meaning New Stone Age.
Tinnitus is ringing, buzzing, or other sounds in the ear. Loud noise can also cause other physical problems, such as: 1  High blood pressure. 2  Increased or abnormal heart rate. 3  Upset stomach. 4  Insomnia or difficulty sleeping (even after the noise stops).oise. Loud noise can be very damaging to hearing. Both the level of noise and the length of time you listen to the noise can put you at risk for noise-induced hearing loss. Noise levels are measured in decibels, or dB for short.
Anything in the range of 140 decibels, like a jet engine, is an immediate danger to your hearing. Exposure could create acoustic trama resulting in immediate deafness. Around 125 decibels, roughly as loud as a firecracker, is refered to as the pain threshold. It's the point where your ear interpert the level of sound as physically painful. Prolonged exposure at this level is very dangerous. The average rock concert is 120 decibels. At that volume hearing damage occurs in 7.5 minutes.
