An in-ear hearing protection device is provided. The in-ear hearing protection device includes a microphone (410) configured to receive an ambient sound. The in-ear hearing protection device also includes a processor (420) configured to perform an attenuation function on the received ambient sound to provide an attenuated sound. The in-ear hearing protection device also includes a speaker (440) configured to broadcast the attenuated sound. The in-ear hearing protection device also includes a communication module (430) configured to receive a second attenuation function detail from a second in-ear protection device. The processor is configured to calculate a first attenuation function detail and compare the first and second attenuation function details. The performed attenuation function is based on one of the first and second attenuation function details.
