Also, the closer you are to the source of intense noise, the more damaging it is. Every gunshot produces a noise that could damage the ears of anyone in close hearing range. Large bore guns and artillery are the worse because they are the loudest. But even cap guns and firecrackers can damage your hearing if the explosion is close to your ear. Anyone who uses firearms without some form of ear protection risks hearing loss.
Recent studies show an alarming increase in hearing loss in youngsters.
Evidence suggests that loud rock music along with increased use of portable radios with earphones may be responsible for this phenomenon. A ringing in the ears, called tinnitus , commonly occurs after noise exposure, and it often becomes permanent. Some people react to loud noise with anxiety and irritability, an increase in pulse rate and blood pressure, or an increase in stomach acid. Very loud noise can reduce efficiency in performing difficult tasks by diverting attention from the job. If you must work in an excessively noisy environment, you should wear protectors.
