Anyone who’s experienced unwanted or uncontrolled sound in a home, apartment, business, school, or theater environment knows how annoying it can be. But uncontrolled sound can do more than grate on your nerves; some noises can actually damage your hearing.
High-intensity and high-frequency sounds, are the most dangerous to your ears because of the number and force of the sound waves being transmitted. Even a small increase or decrease in the decibel level has a significant impact on how you hear the sound; a difference as small as 3 decibels is significant because a small increase or decrease in decibel level makes a substantial difference in how listeners perceive the sound. An increase of only 10 decibels actually makes a sound seem twice as loud to the ear–a 100-percent increase.
