Typical noise suppression eliminates low-frequency steady-hums like droning fans and idling freezers. Attune™ II suppresses all of those plus sounds across the spectrum, including sounds that change in pitch and volume like sirens, beeping horns, and kitchen chaos. With Attune II your staff members can speak with customers in a digitally-enhanced quiet zone where they can communicate efficiently and get orders right the first time. Noise doesn't have to be deafening to be distracting. We designed Attune II to reduce the low and mid volume sounds that are a constant of restaurant life by up to 4 times. Attune II can even reduce the loudest sounds encountered in a restaurant by a factor of 2.
