Currently, there are two different types of technology used in today's electronic ear protection:
Peak Clipping, is used by manufacturers such as Peltor and Remington. When an unsafe sound is detected, the unit actually shuts itself off and clips the sound. The electronics rely on the NRR of the cup and revert the unit back to a passive level of protection for a split second until the noise passes and the unit turns back to amplification mode. The second technology used in hearing protection is
Compression Technology, this technology takes an unsafe sound and reduces it to a safe level. The electronics in the unit provide an environment where the user can always hear their surroundings. Many shooters prefer this type of ear protection as it allows them to hear range commands and game as well as their shooting partners.
While each is different in application, both offer more than adequate protection to the average user.
