Airport noise can be an emotionally volatile issue in municipal politics. However, Robert Grotell thinks data, not emotion, should drive decisions about airport and air route noise abatement.
Sennheiser’s updated active noise cancellation HMEC 26-2 headset adds comfort, noise protection and a higher sound pressure level to the HMEC 26. To improve the fit for a wider variety of pilots, Sennheiser redesigned the two-piece automatic headband so it can be opened another 20 degrees. Restricting folding of the ear cups to a 45-degree angle improves wearing stability. The microphone boom is made of a new steel that remains in the set position more securely, according to Sennheiser.
