Loud noise is not only featuring Damaged Hearing

Listening to loud music is one form of exposure to noise pollution . Therefore , in general the main concern of the negative impact was loud in their ears .
However, these negative effects may not only for the health of the ear . A new study found that the effects of damage from loud noise can even spread to other parts of the body thereby increasing the risk of cardiovascular disease and sleep disorders .
" In everyday life , a loud noise is unavoidable and availability is rarely a quiet place . That is why , we must better understand the noise exposure to our overall health , " said study co-author Dr. Mathias Basner , assistant professor of sleep and chronobiology at the Perelman School of Medicine , University of Pennsylvania .
Loud voice , he added , can stem from many things , such as listening to music too loud , the vehicle horn sound , alarm , or machines . Without conscious these voices can have adverse effect for many parts of the body .



The research team analyzed observational and experimental studies for five years . They found that exposure to loud noise can cause greater impact than just hearing problems , such as sleep disorders .
The impact is then known to be associated also with increased risk of hypertension , ischemic heart disease , stroke , and decreased cognitive abilities in children .
Unfortunately , until now researchers have not been able to determine the loudness limit considered safe .
Two studies in October found that the loud noise from aircraft have a negative impact for people who live in Area airports . The researchers found the risk of heart disease participants 10-20 percent higher than those who stay away from the airport .
