DESCRIPTION
Digital noise reduction that removes intermittent sounds like barking dogs and passing vehicles. DNR-18: the advanced digital CPU eliminates intermittent interfering noises, like passing vehicles, people talking, and pedestrian footsteps.
Traditional band-pass filters filter continuous noises, such as A/C hum, idling motors, and wind. While traditional filters are very useful, they are not able to filter out the common, intermittent noises with broad frequency ranges.
DNR-18 has optional accessories for water leak “pinpointing” and water leak “surveying”.
Graph the leak sound levels at 5-10 spots directly over the pipe. Let the DNR-18’s amplifier pinpoint the leak’s location for you instead of relying upon your hearing.
