Figures & data
Figure 1. The cumulative number of participating countries or regions implementing newborn hearing screening (NHS) and universal childhood hearing screening (CHS) with pure-tone audiometry screening (PTS) according to the reported year of implementation. Information on implementation year was available for 28 NHS and 11 universal CHS programmes. All programmes with universal CHS used PTS. PTS started as early as 1950 with a slow spread across participating countries or regions. Only four implemented new programmes since 2000. Two programmes implemented PTS after NHS. No information was included about the use of other methods for CHS (e.g. the distraction test) in these countries. The first NHS programme was implemented in 1994 with a rapid increase from 1995 to 2010.
