The ALFTECH Pink Noise Generator offers reliable and programmable "Pink Noise" audio output for Sound Masking in environments that needs to "cover up" unwanted sound by using acoustic masking. The ALFTECH Pink Noise Generator reduces or eliminates awareness of unwanted and distracting sounds with a more soothing and less intrusive sound masking existing sounds.

Optional RS-232 serial communications (PING-RM1 +S model) allow external triggers to activate pink noise output and ramp-up/down durations.

The ALFTECH PING-RM1 is used in enclosed public spaces, shop fronts and malls, auditoriums, reception areas, hospitals, waiting rooms, and restaurants to masks unwanted noise.
