Active noise reduction is a successful addition to passive ear-defenders for improvement of the sound attenuation at low frequencies. Design and assessment methods are discussed, focused on subjective and objective attenuation measurements, stability, and high noise level applications. Active noise reduction systems are suitable for integration...

A laboratory model of the wireless "Communications EarPlug" (w-CEP) was developed. Standard communication earplugs (using wires) are known to offer relatively good intelligibility of intercom speech at high ambient noise levels. The intercom sound is produced by means of a commercially available miniature transducer, integrated in the earplug....
