Introduction: Elevated hearing thresholds have been documented in some astronauts after long-term spaceflights although noise levels were lower than those normally associated with noise-induced hearing loss in ground-based operations. The present study was conducted to determine whether prolonged exposure (70 h) to levels (72 dBA) recorded on...

Hearing protection with standard passive earmuffs is for many military applications insufficient. Low frequency noises (diesel engines, helicopter rotor) require increased attenuation. Active Noise Reduction (ANR) is specifically suited for reduction at low frequencies. Assessment of ANR for military applications is an important topic as the...
