Doctors believe that exposure to loud sounds is one of the main factors that contributes to hearing loss as you age.

To know if a sound is loud enough to damage your ears, you need to know both the loudness level and

the length of exposure to the sound. Experts agree that if we are exposed to noise above 85dBA over time, it will

cause hearing loss. In general, the louder the noise, the less time required before hearing loss will occur.

According to the National Health Institute, the maximum exposure time at 85 dBA is 8 hours. At 110 dBA, the maximum

exposure time is one minute and 29 seconds.* required를 require의 과거 동사가 아닌 time을 꾸미는 과거분사로 보고

before hearing loss will occur할 때 will은 미래 시제를 뜻하는 will이 아니라

사물의 성향을 나타내는 will : ex) Traffic accidents will happen. 교통사고는 일어나게 마련이다.
로 보려고 하는 데 맞는 지 모르겠습니다.
