Repeated exposure to loud noise, such as gun shots, will cause permanent hearing loss. This damage is not immediately apparent but accumulates over time. Normally, you can hear sounds from 20 to 20,000 cycles per second. After shooting weekends, you may suffer hearing loss above 8000 cycles.
Most clubs and shooting ranges require eye and ear protection. Sold in one pair of rubber ear plugs with a bright cord to prevent loss. Includes a plastic storage case. Ready for use.
