Maskers can be a wearable small electronic device that fits in the ear or a tabletop masker device that can be placed at bedside to help people with sonus complete to relax or fall asleep. I remember myself one day eating a bag of chips from the 'chippy' - those of you who are from the UK will know what I mean. Sometimes this type of sonus complete may seem like the sound is coming from inside the head.
