Due to a closed canopy as well as an enclosed engine and exhaust system ArrowCopter has noticeably the quietest noise level of any gyrocopter on the market.
Flying ArrowCopter makes only 65.1dBA which is for comparison less then vacuum cleaner that is on 70dBA or just 5dBA more then restaurant/office conversation between few people
