![]() Relaxed conversation, ordinary suburban activityĪ busy office or restaurant noise, loud conversation Library noises, quiet urban background noise To measure the sound level, there are three main methods:ġ. Typically, the higher the pressure a sound has, the less the time duration that would be required for damage to occur.Ī sound at 120 dBA can begin to damage your hearing after only about 20 minutes while a sound at 85 dBA could take as long as 8 hours to eventually result in permanent damage.ĭecibels are a base 10 logarithmic unit which implies that sound intensity would double if it is increased by 10 decibels. ![]() Also, the intensity of pressure accompanying a sound determines the duration it would take to cause damage. Loud sounds as high as 85 dBA could lead to permanent ear damage. ![]() Some musical concerts such as a rock concert can make sounds as loud as 120 dBA. Research has shown that the softest sound level that can be heard by humans is 0 dBA and a normal speaking voice is around 65 dBA. Amplitude refers to the force of a sound wave, and it is usually measured in dBA which implies decibels of sound pressure. The energy in a sound wave is measured in units called decibels. The ability to measure sound level is essential to help determine the fine line between the sound that can be accommodated by human ears and that which would most likely cause damage of some kind. ![]() We receive a commission on purchases made from our chosen links (at no extra cost to you). ![]()
