For extremely demanding noise exposure
A brand new technology of hearing protection, with dual cup shells minimizes and provides optimum attenuation at higher cup resonance frequencies and increases speech and signal intelligibility. The inside cavity and the cavity between the two shells are acoustically matched for optimum low frequency attenuation. Comfortable wide cushions are filled with a soft foam material for outstanding fit and reduced contact force. Additionally, an acoustically controlled super-attenuator provides effective protection and superior comfort. |
